Overview
Specimen Track Gigabit Ethernet 16 E1 To GE PDH Multiplexed Fiber Optic Transmission is a compact size, PTP and PTMP transmission equipment that easily bring the E1 and Ethernet services to customer premises or remote end office. It operates at 1.25 Gbps transmission rate over the optical cable, with enough bandwidth to carry 16 x E1s, as well as 4 x 10 or 100 or 1000 M switching Ethernet data. These four Ethernet ports could be 4 electrical GE interfaces or 3 x electrical GE interfaces plus 1 x SFP gigabit optical ETH interface. It is designed with 2 interface slots on the rear panel to adapt different E1 card modules, so it can carry from 4 x E1 up to 16 x E1 due to customer requirement.
