High-performance GPON for FTTx Applications PLANET GPL-8000 GPON Optical Line Terminal (OLT) consists of eight GPON ports, four Gigabit TP/SFP combo ports, four Gigabit SFP ports, four 10G SFP+ ports and one management port. It complies with ITU-T G.984/G.988 and meets the requirements about GPON OLT in network access technical requirements.    It is easy to install and maintain a GPON deployment up to 1024 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-8000 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-8000 is an ideal solution for FTTx applications. It helps to minimize the investment cost for carriers by offering a high split ratio of 1:128 per port and supporting the usage of PLANET ONUs. The GPL-8000 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-8000 has four 10G SFP+ uplink ports to deliver ultra-high speed networking over long distances to service providers. Each of the 10G SFP+ slots supports dual speed and 10GBASE-SR/LR or 1000BASE-SX/LX. With its 4 ports, 10G Ethernet link capability and additional 8-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-8000 provides broad bandwidth and powerful processing capacity for FTTx applications for distribution data link.   Extractive Power Supply Design to Increase Flexibility The GPL-8000 is equipped with one extractive 100~240V AC power supply unit, so it is easy to replace the power for users. Besides, the GPL-8000 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 Routing Support The GPL-8000 enables the administrator to conveniently boost network efficiency by configuring Layer 3 static routing manually, the RIP (Routing Information Protocol) or OSPF (Open Shortest Path First) settings automatically.  The RIP can employ the hop count as a routing metric and prevent routing loops by implementing a limit on the number of hops allowed in a path from the source to a destination.  The OSPF is an interior dynamic routing protocol for autonomous system based on link-state. The protocol creates a link-state database by exchanging link-states among Layer 3 switches, and then uses the Shortest Path First algorithm to generate a route table based on that database.   Robust Layer 2 Features The GPL-8000 can be programmed for basic switch management functions such as port speed configuration, port aggregation, VLAN, Spanning Tree Protocol, WRR, bandwidth control and IGMP snooping. It also supports 802.1Q tagged VLAN, Q-in-Q and GVRP Protocol. In addition, the number of VLAN interfaces is 4K. By supporting port aggregation, the GPL-8000 allows the operation of a high-speed trunk combined with multiple ports. It enables up to 32 groups for trunking with a maximum of 8 ports for each group.   Efficient and Secure Management For efficient management, the GPL-8000 is equipped with console, Web and SNMP management interfaces.  With the built-in Web-based management interface, the GPL-8000 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-8000 offers secure remote management by supporting SSHv2, TLSv1.0 and SSLv3 connection which encrypts the packet content at each session.
