pdh modem

Detailed Product Description

pdh

Model name: BD-OP-E1
Product function: E1 fiber modem is to modulate framing (N*64Kbps) to single or multi-mode fiber. E1 time-slot, wavelength of ordinary fiber, and type of interface is configurable. Suit for transmit additional management data channel in different fibers.The fiber for transmit data can be used to monitor and control local and remote devices, and no collision will occur. It can also be used pair with V.35 fiber modem.
