GTT-120H-30IntegratedServiceOpticalTOverviewHseriesmulti-serviceopticalterminaladoptLSIwithproprietaryintellectualpropertyrights
Overview
H series multi-service optical terminal 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. Each service adopt isolated transmission channel, guarantee the full-duplex mode of Ethernet line rate, support two Ethernet channel, and can reach physical isolation. This system realized perfect combination of transmission, broadbａnd and PCM equipments. This equipment adopts the design of 19-inch, 1U frame, high integration, small size, low power dissipation, reliable operation and easy installation and using. 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.
Main feature
★ Provide 2 routes 10/100M self-adapting Ethernet interfaces, full-duplex/half-duplex self-adapting; can select two Ethernet interfaces physical isolation
★ Provide 4 or8 routes E1 interfaces, all-digital clock recovery and smooth phase-locking technology
★ Provide 15 narrowbａnd service slots, FXO/FXS, EM2/4, hotline, magnetic, RS232/RS485 arbitrary configuration
★ Coordinate with MUX series multiplexing equipment of our company, provide up to 150 routes voice maximum, support caller ID detection
★ Support single fiber duplex analog mode, saving fiber resource
★ The power has DC-48V, DC+24V, AC 220V etc electric supply mode selected
★ Provide perfect local/opposite alarm monitoring, three-color light indicating
★ Support local/remote E1 branch loop
★ Transmission distance without delay more than 40Km, 120Km maximum
