PLANET EPL-1000 - Manual (Page 6)

1. Introduction
EPON is a point to multipoint communications protocol based on Gigabit Ethernet. It
allows a Gigabit Ethernet communications fiber 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 traffic flows from OLT to ONU, and upstream traffic flows 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 fiber.
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 fulfill 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.
