EPL-4000 Planet GEPON OLT

 Perfectly Designed for FTTx Applications

PLANET EPL-4000 GEPON Optical Line Terminal (OLT) consists of four GEPON ports, four 1G/10G shared SFP+ ports, four GbE RJ45 interfaces and one management port. It is easy to install and maintain a GEPON deployment. With PLANET GEPON Optical Network Unit (ONU) EPN series, the EPL-4000 can provide highly-effective GEPON solutions and convenient management for broadband network. PLANET GEPON technology provides a high bandwidth of up to 1.25Gbps for both upstream and downstream, long-distance coverage of up to 20km between equipment nodes, and flexibility for network deployment. It is a cost-effective access technology with reliable and scalable network for triple-play service applications.

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-4000 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-4000 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-4000 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-4000 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-4000 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-4000 has eight uplink ports. The four mini-GBIC slots of the uplink ports of the EPL-4000 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.

Applications

Cost-effective, Long-distance and High-bandwidth Triple Play or Surveillance Applications

PLANET EPL-4000 delivers high-speed voice, data and video services to residential and business subscribers. With the PON technology, the EPL-4000 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-4000 is the perfect solution for triple play or surveillance applications by offering benefits of cost-effectiveness, scalability and flexibility to network deployment.
