16E1 4GE Fiber Optical PDH Multiplexer supporting P2P Ring and daisy chain application

Description

BD-OP-64E1-4GE-V is optical transmission equipment based on application specific integrated circuit (ASIC). It is called 16e1 4GE fiber optic multiplexer. The 16E1 PDH multiplexer supports 1+1 SFP socket optical port backup. It supports P2P application, ring and daisy chain topologies.  The 16E1 pdh optical multiplexer multiplexes 16 E1 and 1000Mb/s Ethernet to optical fiber ports. With the feature of ADM, E1 can be configured to add/drop at one element of the network in chain or ring topology. All E1 can be fast protected when any failure occurs for ring topology application. In a chain or ring network, the gigabit Ethernet channel is shared by all elements, and 50ms self healing is also achieved in case of failure of ring topology.
In point-to-point mode, the Ethernet transmission bandwidth can be doubled to 2.5G by setting the port-aggregation function.
The 16E1 pdh multiplexer supports SNMP management, dual 220VAC and 48VDC power supply redundancy and IU 19-inch rack-mounted unit.
16E1 4GE pdh optical multiplexer has the following interfaces;
16x E1 G.703;
three built-in electrical Ethernet ports (10/100/1000) Mbps;
Fiber optic Ethernet port (SFP socket) 1000Mbps.
