E1/T1 Fiber
Revision January 2000
E1/T1 Fiber Mux/De-mux over Fiber Optic Cable DESCRIPTION FEATURES ACS411CS comprises chip three highly Three chip supporting full duplex serial data
integrated devices, ACS9020 ACS4110. ACS9020 analog transceiver ACS4110 mixed signal device. ACS411CS supports full duplex serial data 51.84Mbps over both single twin fiber with link lengths 90km (link budget dependent). available bandwidth shared over channels E1/T1 plus 256kbps maintenance channels. ACS9020 integrates Laser/LED driver well receiver circuitry including post amplifier. minimise cross talk maximise optical link budgets, ACS9020 devices required, configured transmitter other configured receiver. ACS4110 integrates multi channel mux/demux logic with de-jittering circuits each channel, plus clock data recovery. ACS4110 supports parallel microprocessor interface device configuration (control), link configuration link monitoring/status analysis. This enables link configuration (remote control) directly pins basic device setup. transmission 51.84Mbps over twin optical fiber, fiber with WDM. Multi-channel operation with full loopback diagnostics channel configurable parallel microprocessor interface. independent synchronous data channels:
(STS1) 51.84Mbps E3/T3 E1/T1
Additional 256kbps maintenance channels with Standard interfaces Line Interface Units (LIU)
Framers. option multi-channel operation framing signal.
Select between pseudo-bipolar HDB3/AMI/ Support LED/Laser LED/Laser Link budgets 27dB with Laser single mode Error Rate (BER) 10-10. Single supply. Operating temperature (ambient) 85°C. ACS9020 available TQFP64 package, ACS4110
