4E1+4*10/100M PDH Fiber Optical Multiplexers Singlemode Dual Fiber 20KM 19 Inch Rack(with the orderwire phone)
The 4E1+4*10/100M PDH Fiber Optical Multiplexers is a fiber media transport for 4E1 + 4 x 10/100BaseT transmission. The BNC model provides unbalanced 75 Ohm coaxial connections while the RJ-45 model provides balanced 120 Ohm connections over twisted pair wiring. All media converters are available with either multi-mode or single-mode optical tranceivers and with connectors for SCor FC. In single mode they are available in up to 120 km versions reach, which will provide the ability to transmit and receive data using only a single optical fiber pair.
