BH series PDH network Optical Transceiver

BH series Multi-service PDH Fiber Optic Multiplexer provides idealsolutions for building fiber-based E1 and IP networks. It converts 4 or 8 or 16E1s plus 4 Ethernet ports data to optical signal and transmits the convertedsignal over the fiber cable.

Ethernettransmission utilizes 4 integrated Ethernet ports which support 802.1Q VLAN Tagfunction. The electrical Ethernet ports can operate in half or full duplexmode. IEEE 802.3x Flow Control and backpressure are also supported.

BH series supports redundant power supply andsecondary link options, enhancing system reliability. The optional secondarylink provides backup using automatic switch over upon main link failure.
