1. Introduction
EPON is a point to multipoint communications protocol based on Gigabit Ethernet.
It allows a Gigabit Ethernet communications ber to be shared by multiple end
users using a passive optical splitter. EPON communication takes place between
an Optical Line Terminal (OLT) and multiple Optical Network Units (ONUs). Using
standard terminology, downstream trafc ows from OLT to ONU, and upstream
trafc ows from ONU to OLT. A protocol called Multi Point Control Protocol (MPCP)
is used to arbitrate the channel between the ONU’s so that no collisions will occur
on the common ber.
With growing network services such as HDTV, IPTV, voice-over-IP (VoIP) and
Multimedia broadband applications, and the demand of broadband rises quickly. The
present Broadband environment has not already accorded with needing; however,
Passive Optical Network (PON) would be the most promising NGN (Next Generation
Networking) technology to fulll the demand.
PLANET EPL-1000 is a GEPON Optical Line Terminal (OLT) which designed with
one GEPON port, one Gigabit TP / SFP Combo Interface and one management
port. It is easy installation and maintenance for GEPON deployment. Applications
with PLANET GEPON Optical Network Units (ONU) EPN series, PLANET EPL-1000
can provide highly effective GEPON solutions and convenient management for
Broadband network. PLANET GEPON technology provides the high bandwidth up to
1.25Gbps for both upstream and downstream, up to 20km Long-Distance Coverage
between equipment nodes, Scalability and Flexibility for network deployment. It is
a cost-effective access technology with reliable and scalable network for Triple-play
service applications.
With high split ratio at 1:32 and support the usage of PLANET ONUs, EPL-1000
can minimize the investment cost for carriers. By using the advanced technology
in the telecommunication industry, the EPL-1000 will provide strong functionalities
for Ethernet features such as QoS, VLAN, Multicast, DBA (Dynamic Bandwidth
Allocation), and Access Control List. The EPL-1000 is an ideal solution for FTTx
applications.
