FiberHome Technologies, the unique telecommunication system supplier that offers both optical fiber and cable as well as optical communication equipment, has over 40 years of experience in optical cable industry and more than 20 years in xPON technology R&D. Currently, FiberHome products are serving more than 20 million subscribers (including China) in Asia Pacific with its FTTH integrated solution. In Asia Pacific, FiberHome is becoming the mainstream provider of FTTH one-stop solutions – FTTH equipment, ODN products and FTTH turnkey services.
ODN construction cost accounts for more than 70% of the overall FTTH network investment. The rationality of ODN network planning and design, the reliability of the products and engineering, the efficiency of network operation and maintenance, and the capability of network evolution have become the key criteria to evaluate whether the FTTH network investment is successful or not.
With many years of experience in the telecom industry and in FTTH network construction, FiberHome is able to provide a smart, flexible, efficient and evolvable FTTH network. This helps save CAPEX and OPEX and raise customer satisfaction.

LONG HAUL MULTI-GIGABIT MICROWAVE: A NEW APPROACHAviat Networks
As the data capacity demand on mobile phone and other wireless operator networks booms, their telecom backbones, or backhaul infrastructures, have struggled to keep pace. To get high volumes of data from coast to coast, operators have in more recent times relied on fiber optic technology for their voice and data traffic. However, for these long-haul operations, fiber lacks practicality, flexibility, cost effectiveness, security and quick time-to-market. Increasingly, operators are turning to the original long-haul telco solution to meet all these needs: microwave radio.

Migration from Copper to Fiber Access Network using Passive Optical Network f...Umar Farooq
Passive Optical Networks (PON) technology
brings an evolution in the industry of Telecommunication for the
provisioning of High Speed Internet (HSI) and Triple Play
bundled Services that includes Voice, Data, and Video Streaming
throughout the world. In Pakistan most of the service providers
are offering broadband services on traditional copper OSP
(Outside Plant) network since 2000. Demand for the high speed
internet and broadband is increasing rapidly, it is desired with
great need to migrate from traditional copper based OSP network
to PON – FTTx (Fiber To The x) infrastructure. Considering the
geographical requirements in Pakistan a scalable fiber network is
required which can be optimized as per the user’s requirements
and demands with high speed bandwidth efficiency, involving the
minimum losses and with ideal capital expenditure (CAPEX). In
this work a platform for migration from copper to fiber access
network with a scalable and optimized PON – FTTx
infrastructure in green field and dry field areas of Pakistan have
been proposed using Geographic Information system (GIS). In
any developing country like Pakistan having the same cultural
and geographical topology, this platform can be used to migrate
from copper to fiber access network to provide the PON based
telecom services. The developed platform for migration from
copper to PON based fiber has been studied, planned, and then
simulated on a selected geographical area of Pakistan with
physical execution that showed better and efficient results with
reduction in capital and operational expenditures. A factual plan
without ambiguities assists the operators of Pakistan to
analyze/forecast bandwidth requirements of an area, optimized
network planning along with the in time and efficient
deployment.
FPGA Implementation of FIR Filter using Various Algorithms: A RetrospectiveIJORCS
This Paper is a review study of FPGA implementation of Finite Impulse response (FIR) with low cost and high performance. The key observation of this paper is an elaborate analysis about hardware implementations of FIR filters using different algorithm i.e., Distributed Arithmetic (DA), DA-Offset Binary Coding (DA-OBC), Common Sub-expression Elimination (CSE) and sum-of-power-of-two (SOPOT) with less resources and without affecting the performance of the original FIR Filter.
In the early days, computer networks were designed without anticipation for future expansion or upgrading. The networks during those days were very small, and the existing equipment which in most cases comprised a computer or two of them together with a printer were connected together in a random manner.

Digital Beamforming for Simultaneous Power and Information Transmission in Wi...idescitation
This paper proposes a Beamforming algorithm for
simultaneous transmission of information and power in multi-
antenna linear array system. Here we considered three node
system in which transmitter and receiver are largely separated
from each other whereas energy harvesting circuit is co-
located with the information receiver i.e. encounters the same
channel from the transmitter. Our primary motto is to
maximize the energy harvested by the harvester circuit, at
the same time maintaining the information rate above a
certain threshold level. Firstly, we used an algorithm to steer
the antenna beam in a desired direction. Secondly, we
combined this algorithm with another algorithm that
maximizes the harvested energy. The hybrid algorithm
produces an improvement in the result in terms of received
signal level and side-lobe level. Finally, simulation results
are presented to justify the effectiveness of the proposed
algorithm.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

From Gartner 2010 actual port shipments FC = 6,444,900 and 10Gb = 4,418,200FC40 and 100 Gigabit Ethernet port volume is projected to be years away and be quite small. Aggregate 40 and 100 gigabit Ethernet ports in 2015 are less than 1% of the total. This forecast will probably change as standards and alternative technologies evolve, but no one knows how.We keep an eye this space, especially for fiber test products. (Good time to whip out a QuickMap). There are too many moving parts regarding copper to make anything but an incorrect prediction today.A Medium Dependent Interface (MDI) describes the interface (both physical and electrical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Implications: It is unclear if 40/100 gigabit will ever be significantOnly FNET has the resources and market investment to “be there” if 40/100 gigabit does become significantThe role of twisted pair at these speeds is a complete guess today
802.3ba is the study group developing the standard for 40 and 100 Gigabit Ethernet
802.3ba is the IEEE standard for 40 and 100 Gigabit Ethernet. This time IEEE grouped together 40 and 100Gigabit. In order to meet the timeframes requested the in the market, when developing the Physical Layer Media Dependent transceivers, they chose to go with mostly known (10Gig) technology which is integrated into a parallel transceiver. The optical PMDs (Physical Medium Dependent [IEEE 802.3]). will be over multi-fiber ribbon fiber using MPO connectors.A short reach copper option is included over twinaxial cable assemblies which is similar to SFP+, except there are four lanes rather than 1.There is not any option for using structured copper cabling (no UTP so STP)
This chart summarizes the actual PMDs (Physical Layer Media Dependent transceivers) options included in the standard.The shorter reach options which are likely used in the data center, 7m cable assembly, and 100 or 150 m over multimode fiber utilize parallel 10Gig sigalling.
This chart represents a roadmapfor ‘current’ and ‘future’ short/longreach Ethernet transceivers.Highlighted are thosePMDs (Physical Media Dependent = Transceiver) for 40 & 100Gb/s Ethernet. Both are definedby IEEE 802.3ba as MPO/MTP form factor connectors.40G: 4 - 10Gb/s lanes of transmit and 4 – 10Gb/s lanes of receive in a 12-fibre MTP100G: 10 – 10Gb/s lanes of transmit and 10 – 10Gb/s lanes of receivetraffic in either a 24-fibre MTP or in 2 12-fibre MTP connectors.Also note thechange in reach of thefuture MM transceivertechnology (from a 300 meter solutionwith OM3 fibre to a 100 meter one & from a 550 meter solutionwith OM4 to a 150 meter solution).Note – 125m isshown in the chart sincethiswasbasedon 1.5dB of connectorinsertionloss and not 1.0dB as appears in thestandardtoday.

Duplex to paralell – is there such a thing as 40 & 100 GbE? Right now, isn’t it really aggrigation?
Currently no switch manufacturers are shipping this configuration
Now THIS is new!
Panduit’s SFQ cassette-based solution is ideal for reducing cable congestion in the Main Distribution Area. Discreet SFQ cassettes deployed for 10G applications are re-purposed elsewhere in the data center when upgrading to 40G. The MTP jumpers that connected to the read of those cassettes are joined together in a QPPABL adapter that occupies one of the panel slots in the QuickNet Patch Panel. The remaining open slots contain tethered SFQ cassettes. This is what enables a 1-to-1 migration from 10G (6 – 10G LC ports per slot) to 40G (6 – 40G MTP ports per slot). Additional slots are required when migrating from 40 to 100G. With the economic, enclosure-less, SFQ solution, Panduit delivers the highest density 40G & 100G solution on the market today.Panduit demonstrates both thought leadership and technical innovation through this system.
So what are the considerations when it come to fiber connectors? The MPO connector is the industry standard for high density fiber deployment. The MPO is used in 10G, 40G, and 100G systems. The most important things to consider when migrating from 10G to 40G or 100G on MPO are gender, polarity, and the key position.So why are these things so important?????
To understand the importance of gender, polarity, and the key position let’s first take a look at the MPO connector and how polarity is dictated by key position:Let’s familiarize ourselves with the features of existing MPO connectors.The MPO connector is a multi-piece fiber connector. It contains.A moveable outer housing that is used to push the connector into an adapter or transceiver. Pull on it to disengage the connector.A connector body housing which has the polarization key molded into itA high precision fiber ferrule which contains the multi-fiber (12 fiber) arrayThe ferrule also contains holes which contain alignment pins (for a male connector) and are left empty for a female connector.The orientation of polarization key may either be up or down with respect to fiber #1 when on a fiber assemblyThe key-up to key-down configuration is called Method (or type) AThe key-up to key-up configuration is known as Method (or type) BGender combinations also are a component of defining an MPO-MPO fiber assembly. They are:Male to Male Male to Female Female to FemaleA few of these are shown on this slide.
Reveiew Method A trunk & key positionsReview Method B trunk & key positionssReview Interconnect pinning and key positions (F/F)Review 10G trunk standard (pinned F/F)Review 40/100G standard (pinned M/M)Go through migration from 10G to 40G with an installed trunk.The potential to have a non-standard system or to be stuck using hybrid cables is very high
Panduit’s new PanMPO connector solves the issues of maintaining polarity and gender through complex fiber channels while maintaining the same high performance of an MTP connector.Explain how to change Polarity & Gender……Panduit still uses the same high precision ferrule and guide pins on this new MPO connector which allow it to deliver the same optical performance found in MTP connectors.
