Optical line termination, 8 uplink ports(4 combo SFP+4 RJ45), 1 PON port and 3 PON slots for GEPON, SM, single fiber, SC/PC connector, 20km, 1x32 PLC, 1490T/1310R, CLI/Telnet, console ports for management, internal power, AC200~240V, 432x 400x 44mm, 19'', 1U. price with 1 PON port. Features: ◇ IEEE802.3ah compatible ◇ 4 downstream PON ports ◇ 32 optical branches per OLT port for connection of up to 32 ONUs ◇ Downstream transmission up to 20kilometers ◇ 128 subscribers served in one compact 1U chassis ◇ It adopts the point-to-multipoint network topology, effectively collects separate Ethernet services and aggregates them on the MAN node. It connects the upper-layer devices through the GE interface and can be connected to the existing network smoothly ◇ The Dynamic Bandwidth Allocation (DBA) mechanism enables all users to share the 1Gbps bandwidth reasonably, guaranteeing a reliable QoS ◇ The Rapid Spanning Tree Protocol (RSTP) enables the redundant interconnection between OLT and backbone network ◇ Support IGMP multicast and efficiently utilizes the bandwidth. ◇ Support multicast VLAN ◇ Support broadcast of IPTV, voice and data simultaneously ◇ Support network management of inner bandwidth and outside bandwidth ◇ It has rich OAM functions such as configuration, alarm, performance monitoring, trouble isolation and security management. At the same time, it supports the CLI/TELNET/CONSOLE management, which is easy to use Description OLT1000C is an OLT device which complies with IEEE802.3ah and PRC communication industry standard (YD/T 1475-2006). When it works together with the ONU400C/1000C ONU products, an efficient EPON solution can be established. The modularized OLT supports the 1Gbps PON transmission rate. Its efficient bandwidth usage and Ethernet service supporting help carriers to provide reliable services to their users. Its coupling ratio, 1:64, and its support of different hybrid ONU networks minimize the carrier’s investment. The GEPON system uses a single optical fiber for both upstream and downstream transmission. Downstream traffic is sent via 1490nm wavelength and upstream traffic uses the 1310nm wavelength. The 1550nm wavelength is reserved for future CATV or wavelength division multiplex (WDM) upgrading. It is a fiber to the Home (FTTH) platform providing up to 1Gb/s Ethernet data and optionally video and voice on IP(VOIP)services to commercial and residential end users.
