Introduction

Fiber-To-The-Home (FTTH) has always been an attractive option for Internet
access. It has all the benefits of optical fiber. It provides a future-proof network, in
that you do not have to go through the hassles of upgrading from ADSL to xDSL, or
digital co-ax to digital wireless. It does not have to struggle with electromagnetic
interference problems, and with no active “outside-plant” components, it offers the
highest reliability. Moreover, it does not require electric power and is immune to
lightning and other transients. These properties of fiber lead to the lowest possible
power and operational costs, such as maintenance, provisioning and facilities
planning.

The EC3802-WDM Media Converter is an ideal Customer Premises Equipment
(CPE) for an FTTH system. This CPE is a single-channel fiber-to-copper media
converter housed in a compact unit. It allows a service provider to extend an
Ethernet connection over optical fiber directly to a subscriber. The CPE has an
embedded (no external plug/socket) ITU-T G.985 full-duplex single-fiber
single-mode cable connection that runs from the service provider’s central office
(CO). The single-mode fiber connection can be run up to distances of 15 km from
the CO. The CPE also provides one standard 10/100BASE-TX RJ-45 Ethernet port
for connecting to a customer’s PC, switch, or other network device using twisted-pair
cable.
