GTT120HMulti-serviceOpticalMultiplex1
1. Overview
GTT 120H multi-service optical multiplexer adopt LSI with proprietary intellectual property rights, using TDM technology, mix the Ethernet, E1 signals and narrowbａnd service, such as voice etc encoded and transmitting through a couple of optical fiber. Realize the mixed transmission of 10/100M Ethernet service, E1 service, speech path service, 2/4EM, RS232 or RS485 service etc. Extensive apply in telecom operator telephone bar, major client access, project of optical fiber replaced copper wire and electric power substation communication, public security bａnd four network access, army etc.
2. Performance feature
Provide 2 routes 10/100M self-adapting Ethernet interfaces, full-duplex/half-duplex self-adapting;
