1. VISTA 1600C Optical Line Terminal OLT
Optical Terminal
� High-density integrated PON Service Interface
1U standard Pizza Box, compact structure achieving the industry's highest integration. Main board builts 2
PON interface and 4 PON slots together, support 4 PON CARD hot-plugging maximum (8 PON interface).
It can supply the service for 640 ONU maximum (1:64 branching ratio).
� Powerful data transmission capacity
As high as 68Gbps non-blocking full line rate for data transmition, more than twice as big as the ordinary
1U OLT. It has rich uplink interface: including 4*10/100/1000 BASE-T Ethernet interface, 4 * 1.25Gbps SFP
module slots, and 1* 10G uplink stacking interface.It can really provide service bandwidth without bottleneck.
� Advanced 2.5G Turbo EPON Technology
The use of industry-leading 2.5Gbps Turbo-EPON technology, so that each PON interface is extended
bandwidth of downstream data transmission to 2.5Gbps. In full loading, 9 PON interfaces can be extended to
2.5Gbps, so that the system downsteam bandwidth can be extended to 22.5Gbps totally, more than 4 times
as big as the bandwidth of ordinary 1U OLT.
� Dual redundant power backup and self-recovery
-48V DC and 220V AC dual power supply redundancy backup and run in load sharing mode, hot-swap
automatically without any service interruption if there is any failure with power. When the power with failure of
over-current / over-voltage is recoveried, it can resume working automatically.
� 1:128 Optical branching ratio
VISTA 1600C can be upgraded optical branching ratio to 1:128 maximum with special laster module,it means a
PON interface can provide service for 128 ONU maximum. The normal optical branching ratio is 1:64 with standard
optical modules.
� Long diatance of data transmission
The data transmission distance between OLT and ONU can be upgraded to 60 kilometers maximum, without
any transit device, beyond 3 times as far as distance of the standard EPON.
� Hot-plug components designing
Hot-plug
All the interfaces, modules, cards on front or back panel can be hot-plugged arbitraryly,such as:
-48V DC power supply module, 220V AC power supply module, uplink copper interface ,PON card and so on.
Any component has been hot-plugged without effect on system.
� Protection and swapping of optical trunk line and PON service interface
Optical trunk line and PON service interface can be set 1+1 backup protection with Suitable optical switch.
Standby one can be swapped automatically if system has some problem with master optical trunk line or master
PON service interface, and when the master one has recoveried, it will be swapped automatically again.
� Maximum throughput of PON service interface
Based on optimizing parameters, the maximum throughput of 1G PON service interface can be 990M upstream
and 998M downstream .That is much higher than other similar one.
� Stackable expansion designing
Two OLT main board can be stacked to be a device in OLT stacking mode, so that the number of system
PON interface is expaned to 18 as much as frame-type device.

2. � Virtual LAN
System supports IEEE 802.1Q,VLAN base on ONU, VLAN tag / untag, transparent VLAN, vlan translation,VLAN
priority tag, VLAN filtering. The capacity of OLT VLAN is 4094. VLAN ID range is from1 to 4094 and VLAN ID1
is reserved. OLT supports VLAN trunk and SVLAN trunk, VLAN Stacking based on IEEE 802.1ad standard.
It supports the tag is mapped to SVLAN ID based CVLAN ID or CVLAN priortiy.
� Multicast Function
system supports IGMP Proxy, implemented by SCB in pon. Each ONU supports 16 multicast groups. OLT
supports 256 multicast groups maximum. CTC controllable multicast is implemented by OLTand ONU together.
User permissions can be identified based on user label information carried in multicast protocol packetes.
Some relative OAM is available for network management system.
� Access Control List
System can filtrate and inhibit broadcast frames, multicast frames, unicast frames according to
source / destination MAC address, source / destination IP address, source / destination TCP or UDP port,
VLAN ID, specific physical ports, and protocol type. It can filtrate illegal frame and multicast source, and
prevent MAC address spoofing by discarding Ethernet frame with unknown source MAC address.
� Link Aggregation
System supports link aggregation on uplink ports, 14 link aggregation groups can be set. The service can be load
shared to each port of link aggregation groups based on source / destination MAC address, IP address and ports.
� Dynamic Bandwidth Allocation
System supports dynamic bandwidth allocation. Bandwidth allocation is implemented by SLA which is allocated to
LLID . Minimum bandwidth allocation granularity is 1Kbps. Guaranteed bandwidth、Best effort bandwidth and
priority can be set for each LLID. Fairness of bandwith allocation for LLID with the same priority can be guaranteed
by previous flows. QoS of the network is implemented by Guaranteed bandwidth.
� Quality of service
System supports flow classification, marking, queuing and scheduling based on LLID, MAC DA, MAC SA,
User Priority (IEEE802.1D), Ethernet type (such as PPPoE, PWE3, MAC Control, etc.), source / destination IP
address, IP protocol type (TCP, UDP, ICMP, IGMP, etc.), IP TOS / DSCP, L4 protocol ports and so on.
� Encryption
System supports AES-128 encryption transmission bi-directionally and triple Churning downstream for each LLID
� Spanning Tree Protocol
System supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP).
� Device management
OLT, ONU can be upgraded online remotely. All the configuration parameters of the system can be saved in
FLASH, without loss after power-off or restart.
