GTT GL120H Multi-service Optical Multipl
1. Overview
GTT GL120H 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 4 routes 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 4 routes line-rate physical isolation 10/100M self-adapting Ethernet interfaces, full-duplex/half-duplex self-adapting;
Provide 4 routes E1 interface, all-digital clock recovery and smooth phase-locking technology;
Provide 15 narrowband service slots, FXO/FXS, EM2/4, hotline, magnetic, RS232/RS485 arbitrary configuration;
Provide 30 routes voice maximum, support caller ID function;
Optical interface is FC interface (also SC interface);
Optical interface can select single fiber or dual fiber, standard configuration transmission distance is dual-fiber 40KM, single-fiber 20KM, maximum transmission distance 120KM.
