PDH Multiplexers

Image of PDH Multiplexer (fiber optic multiplexer).jpgPDH Multiplexers: STM1-1 fiber converter, V.35/ E1/RS485 fiber modem, E1/2E1/4E1/8E1/16E1 (120ohm/75ohm) fiber optical multiplexer, 1+1 PDH multiplexer, NxE1+1/2/4ETH optical multiplexer, 4U/6U chassis, Phone optical multiplexer; card type or standalone in mini rack or 19inch rack; dual fiber/single fiber with SC/FC connector; 220V/110V/48V or both power supply; transmitting distance up to 120km.

Sopto PDH Multiplexers are E1 point-to-point optical transport equipments that use the FPGA chips and easy to upgrade. It is single board structure, and the largest transmission capacity is 16E1. The outer design use the standard 19 inches rack, so the volume is little, weight is light, the operation is convenient and credit.
 
N*E1 PDH Fiber Optic Multiplexers use the PDH fiber transmission technologies. The 2M (E1) interfaces can connect with the exchanger, light loop device and multi-diplexer directly to form the micromini or the special network. Complete alarm function for N*E1 PDH Fiber Optic Multiplexers, it is stable, easy to maintenance and install, small in size. It can support one digital service telephone. Sopto manufacture E1 Fiber modem, 4E1, 8E1, 16E1 Fiber Optical Multiplexer and Chassis.
