High-performance GPON for FTTx Applications
PLANET GPL-1000 GPON Optical Line Terminal (OLT) consists of one GPON port, two Gigabit Ethernet ports, one 10G SFP+ port and one management port. It complies with ITU-T G.984 and meets the requirements about GPON OLT in network access technical requirements.
It is easy to install and maintain a GPON deployment up to 128 ONU and HGU devices, providing highly-effective GPON solutions and convenient management for fiber optic broadband network.

High-speed and Long-distance Coverage for Triple Play Services
The GPL-1000 provides a high bandwidth of up to 2.5Gbps for downstream and 1.25Gbps for upstream, 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 such as HDTV, IPTV, voice-over-IP (VoIP) and multimedia.
High Split Ratio for a Cost-effective Network Solution
The GPL-1000 is an ideal solution for FTTx applications. It helps to minimize the investment cost for carriers by offering a high split ratio of 1:128 per port and supporting the usage of PLANET ONUs. The GPL-1000 provides strong functionalities for Ethernet features such as VLAN, Dynamic Bandwidth Allocation (DBA), Service Level Agreement (SLA) and Access Control List. GPON protocol allows a Gigabit Ethernet communications fiber to be shared by multiple end users using a passive optical splitter.
Flexible and Extendable 10Gb Ethernet Solution
The GPL-1000 has one 10G SFP+ uplink port to deliver ultra-high speed networking over long distances to service providers. The 10G SFP+ slot supports dual speed and 10GBASE-SR/LR or 1000BASE-SX/LX. With its 10G Ethernet link capability and additional 2-port 1G Ethernet link capability, the administrator now can flexibly choose the suitable SFP/SFP+ transceiver according to the transmission distance or the transmission speed required to extend the network efficiently. The GPL-1000 provides broad bandwidth and powerful processing capacity for FTTx applications for distribution data link.
Extractive Power Supply Design to Increase Flexibility
The GPL-1000 is equipped with one extractive 100~240V AC power supply unit, so it is easy to replace the power for users. Besides, the GPL-1000 reserves another backup power slot on the rear panel and users can add the second AC or DC power to the redundant power supply installation. The AC power or DC power is optional. The redundant power system is specifically designed to handle the demands of high-tech facilities requiring the highest power integrity.
Layer 3 IPv4 and IPv6 Software VLAN Routing for Secure and Flexible Management
To help customers stay on top of their businesses, the GPL-1000 not only provides ultra high transmission performance and excellent Layer 2 technologies, but also IPv4/IPv6 software VLAN routing feature which allows to crossover different VLANs and different IP addresses for the purpose of having a highly-secure, flexible management and simpler networking application.
Robust Layer 2 Features
The GPL-1000 can be programmed for basic switch management functions such as port speed configuration, VLAN, Spanning Tree Protocol, WRR, bandwidth control and IGMP/MLD snooping. It also supports 802.1Q tagged VLAN, Q-in-Q and DSCP Protocol. In addition, the number of VLAN interfaces is 512.
Efficient and Secure Management
For efficient management, the GPL-1000 is equipped with console, Web and SNMP management interfaces.
- With the built-in Web-based management interface, the GPL-1000 offers an easy-to-use, platform-independent management and configuration facility.
- For text-based management, it can be accessed via Telnet and the console port.
- For standard-based monitor and management software, it offers SNMPv3 connection which encrypts the packet content at each session for secure remote management.
Moreover, the GPL-1000 offers secure remote management by supporting SSHv2 connection which encrypts the packet content at each session.
Cost-effective, Long-distance and High-bandwidth Triple Play or Surveillance Applications
PLANET GPL-1000 delivers high-speed voice, data and video services to residential and business subscribers. With the PON technology, the GPL-1000 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 GPL-1000 is the perfect solution for triple play or surveillance applications by offering benefits of cost-effectiveness, scalability and flexibility to network deployment.
