32 channel fxo fxs analog audio fiber optic transmitter and receiver

Product: 32-Ch Telephone over fiber multiplexer

Model: LNK-PH32 SeriesOverview

LNK-PH32 Series is a new generation highly-integrated single-board PCM base group multi-connection equipment based on independent software and thick & thin film technology. It can provide a 32-line voice interface directly upon the optical transmission channel with a 4-line E1 interface, a 4-line (100M shared) Ethernet data interface. Voice Broadband Optical Multiplexer is mainly used in implementing connections between telephones and SPC exchanges through transmission network, as well as providing various kinds of data operation interfaces.

The device is widely used in: places such as telephone bars, middle and small scale companies, expressways and some temporary construction sites which demand quick solutions to the need of telephone and data operation, and the “Village-village Connection” telephone accessing project which is now in progress.
