PLANET EPL-2220 GEPON Optical Line Terminal (OLT)

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-2220 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-2220 provides strong functionalities for Ethernet features such as VLAN, Multicast, DBA (Dynamic Bandwidth Allocation), and Access Control List besides GEPON, a point to multipoint communications protocol 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-2220 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-2220 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. The EPL-2220 also supports standard Simple Network Management Protocol (SNMP) and can be managed via any standard-based management software.

Robust ONUs Management
The EPL-2220 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-2220 has four uplink ports. The two mini-GBIC slots of the uplink ports of the EPL-2220 are compatible with 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 to distribution data link.

Applications

Cost-effective, Long-distance and High-bandwidth Triple Play or Surveillance Applications
PLANET EPL-2220 delivers high-speed voice, data and video services to residential and business subscribers. With the PON technology, the EPL-2220 offers competitive advantages including a long-term life expectancy of the fiber infrastructure, lower operating costs from the reduction of "active” components, support of up to 20km distance between equipment nodes, easy Installation and maintenance, and most importantly, offering of much greater bandwidth. The EPL-2220 is the perfect solution for Triple Play or surveillance applications by offering benefits of cost-effectiveness, scalability and flexibility to network deployment
