This document discusses five common modes of optical fiber access: 1) Optical Fiber + Ethernet Access which uses switches, photoelectric converters and Cat5e cabling for residential and commercial buildings; 2) Optical Fiber + HomePNA Access which connects to existing coaxial cables and telephone wiring using HomePNA switches and modems; 3) Optical Fiber + VDSL Access which provides data transmission over copper wires and coaxial cable using VDSL switches and equipment; 4) FTTx + LAN Access which aims to provide Gigabit Ethernet, fast Ethernet, and 10Mbps Ethernet to communities, buildings and users; and 5) Optical Fiber Access with 2-155Mb

Optical fiber broadband is a technology that converts electrical signals carrying data to optical
signals and sends the optical signals through transparent glass fibers. The signal conversion process
is completed through the optical modems installed on both ends of the optical fiber. Among various
transmission media for the broadband network, optical fiber is an ideal one, which features in large
transmission capacity, high transmission quality, long repeater spacing and low loss.
Optical fiber access technology provides users with high-speed bandwidth of 10 Mbps, 100 Mbps
and 1000 Mbps that can be directly connected with the main crunodes of the internet. With high
speed access to local area network (LAN) and high speed interconnection with internet, optical fiber
access technology is applied mainly to LANs for business groups and intelligent residences. This
article will introduce five common access modes of optical fiber.
Optical Fiber + Ethernet Access
Ethernet is a kind of technology for LANs and metropolitan area networks (MANs). When the optical
fiber is connected with Ethernet, it is necessary to use switch, photoelectric converter and Cat5e.
Applications: residential areas and commercial buildings where generic cabling and system
integration for optical fiber access are completed or easy to be implemented.
Optical Fiber + HomePNA Access
HomePNA is an industry standard for home networking over the existing coaxial cables and
telephone wiring within homes. To connected optical fiber with the HomePNA, HomePNA switch
(Hub) and HomePNA termination equipment (Modem) are important to connect optical fiber to the
HomePNA.
Applications: residential areas and hotel buildings where generic cabling and system integration are
undone or inconvenient to be done.
Optical Fiber + VDSL Access
Very-high-bit-rate digital subscriber loop (VDSL) is a technology providing data transmission over a
single flat untwisted or twisted pair of copper wires and on coaxial cable. VDSL switch and VDSL
termination equipment are essential to connect optical fiber with VDSL.

Applications: residential areas and hotel buildings where generic cabling and system integration are
undone or inconvenient to be done.
FTTx + LAN Access
FTTx stands for fiber to the x, where x stands for home, curb, neighborhood, business, etc (as shown
in the following figure). LAN refers to local area network. FTTx+LAN access aims at Gigabit Ethernet
for the community, fast Ethernet for the building and 10 Mpbs Ethernet for the user.
Applications: it is mainly applied to concentrated residential areas, enterprises and public
institutions and universities and colleges. In FTTx+LAN, generic cabling is done in residential areas,
high-class offices and student dormitories and teacher dormitories in universities and colleges.
Optical Fiber Access
Optical fiber access with transmission bandwidth from 2 Mbps to 155 Mbps is designed for
enterprises and public institutions or groups who need the independent optical fiber-optic
high-speed Internet. Since the bandwidth for upload and download is high, optical fiber access is
suitable for such activities as remote instruction, tele-medicine and video conference.
Applications: it is applied to concentrated residential areas, communities and offices where generic
cabling is done or easy to be implemented. Furthermore, it also applied to enterprises and public
institutions or groups who need the independent optical fiber-optic high-speed Internet.
Optical fiber access is expanding due to the demand for broadband in consumer environment. Thus,
products such as switches, photoelectric converters and transceivers used in optical fiber access are
various in the market. As a professional supplier of optical communication products, Fiberstore
