MSTP PDH Fiber Optic Multiplexer
NIFT-i4ES

Fiber optic multiplexer provides 4/8xE1, 1x10/100Base-T Ethernet Interface , 1xRS-232 Interface and 1 line order-wire. The new generation fiber optic multiplexer could transmit 4/8xE1 data directly through optic fiber, and provides the steady transmission line for computers, routers etc.
NIFT-i4ES fiber optic multiplexer could be used for extending the transmission between distance two Fast Ethernet devices via fiber cable transparently without performance degradation.
