E1/T1 Fiber
Revision March 2000
E1/T1 Fiber Mux/De-mux over Fiber Optic Cable FEATURES DESCRIPTION ACS406CS comprises chip highly chip supporting full duplex serial data
integrated devices, ACS9010 ACS4060. ACS9010 analog transceiver device ACS4060 mixed signal device. ACS406CS supports full duplex serial data 8.448Mbps over fiber with link lengths 25km. available bandwidth shared over channels E2/T2, E1/T1, 1.024Mbps plus separate maintenance channel(s). ACS406CS provides five transmit/receive clock domains enabling four independent E1/T1 channels maintenance channel supported time. ACS9010 transceiver which integrates Laser/ driver well receiver circuitry including post amplifier. ACS4060 integrates multi-channel mux/de-mux logic with de-jittering circuits each channel, plus clock data recovery. Communicating modems automatically maintain synchronisation with each other even when data being transmitted/received. Link lengths from zero maximum distance catered automatically during system synchronisation.
Multi-channel operation with full loopback diagnostics independent synchronous data channels:
E2/T2 E1/T1
