Planet EPL-1000 [3/20] Introduction

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 trafc ows from OLT to ONU, and upstream

trafc 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 fulll 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.
