PLANET EPL-2000 - Manual (Page 7)

User’s Manual of EPL-2000
Robust Layer 2 Features
With a high-split ratio of 1:64 and supporting the usage of PLANET ONUs, the EPL-2000 can minimize the investment cost for
carriers. By using the advanced technology in the telecommunication industry, the EPL-2000 provides strong functionalities for
Ethernet features such as VLAN, Multicast, DBA (Dynamic Bandwidth Allocation), and Access Control List. The EPL-2000 is an
ideal solution for FTTx applications.
GEPON 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. GEPON 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.
