Quad-Gigabit Ethernet and 16 E1s to optical fiber multiplexer (RP103)

Overview

RP103 is a quad-Gigabit Ethernet to optical fiber multiplexer with 4/8/16 E1 interfaces, 4 gigabit Ethernet interfaces and dual 2.5Gb/s optical interfaces, which can realize up to 16 E1s and 4 independent wire-speed gigabit Ethernet channels^* transmission over optical line.

RP103 supports point-to-point, point-to-dual-point, chain and ring topology. With low power consumption, high integration and well stability, it is a cost-competitive solution for the application where gigabit Ethernet and E1 are required simultaneously, such as the telecommunication, the electric power and the finance fields.

^*Note RP103 provides 4 gigabit Ethernet interfaces and 4 independent wire-speed gigabit Ethernet channels, in point-to-point without protection and point-to-dual point(P2DP) mode, the 4 gigabit Ethernet interfaces share 4000Mb/s Ethernet transmission bandwidth, while in chain and ring topology, they share 2000Mb/s Ethernet bandwidth.
