High-speed and Long-distance Coverage for Triple Play Services:
With growing network services such as HDTV, IPTV, voice-over-IP (VoIP) and multimedia broadband applications, the demand for broadband use rises quickly. The present broadband environment has not accorded with needs; however, Passive Optical Network (PON) would be the most promising NGN (Next Generation Networking) technology to fulfill the demand.  High Split Ratio for a Cost-effective Network Solution:
The EPL-8000 is an ideal solution for FTTx applications. It helps to minimize the investment cost for carriers by offering a high split ratio of 1:64 per port and supporting the usage of PLANET ONUs. The EPL-8000 provides strong functionalities for Ethernet features such as VLAN, Multicast, DBA (Dynamic Bandwidth Allocation), and Access Control List. Besides GEPON, the point to multipoint communications protocol is based on Gigabit Ethernet. GEPON protocol 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 ONUs so that no collisions will occur on the common fiber. High Scalability and Flexible OLT Maintenance:
For efficient management, the EPL-8000 supports remote management functions. Via its user-friendly GUI utility, the administrators can manage and configure the OLT and ONU equipment on the central side. The GUI utility supports up to 32 EPL-8000 OLTs to be centrally managed through one control screen. The built-in Element Management System (EMS) offers an easy-to-use management and configuration facility to add to or remove PLANET OLTs and ONUs from the network architecture easily and economically. Its great flexibility is perfect for deployment among different network architectures.  Robust ONUs Management:
The EPL-8000 supports many operating and monitoring functions for efficient ONU management, such as ONU auto-detection, auto-registration, testing link connection, binding MAC address and filtration, bandwidth control, flow control, and multicast stream control. Flexible and Extendable Solution:
The EPL-8000 has 16 uplink ports. Four mini-GBIC slots of the uplink ports of the EPL-8000 are compatible with 10GBASE-SR/LR SFP+, 1000BASE-SX/LX and WDM SFP (small form factor pluggable) fiber-optic modules. The distance can be extended from 550 meters (multi-mode fiber cable) to 10/30/50/70/120 kilometers (single-mode fiber or WDM fiber cable). They are well suited for FTTx applications for distribution data link.
