Chipset Can Multiplex 16 T1/E1 Channels Over A Single Fiber-Optic Cable

Designed to help rev up the long-haul, broadband access capabilities of cellular phone networks, the ACS411 T/E Fiber Access chipset can multiplex up to 16 independent T1 or E1 serial data channels over a single fiber-optic cable. This enables the three-chip set to deliver an aggregate bandwidth of up to 51.84 Mbps (T3/E3/OC-1 rates) on a single channel reaching up to 90 km without using repeaters.The ACS411 chipset operates over twin fiber cables or a single fiber cable with wave division multiplex (WDM). The set consists of the ACS4110 mixed-signal IC that provides 16-channel mux/demux logic, plus clock and data recovery, and two ACS9020 analog transceivers, each packing a transmitter with laser and LED drivers and a PIN receiver with a TIA and post amplifier--the two ACS9020s are said to be needed to eliminate all transmitter-to-receiver crosstalk. The set interfaces to T1/E1 lines through standard T1/E1 framers or LIUs and meets all AT&T, ITU-T and Bellcore specs for jitter attenuation and transfer and for input jitter tolerance. And a customizable µP interface is included for device and link configuration and for link monitoring and status reporting. The set costs $113 each/1000, with the ACS4110 multiplexer device housed in a TQFP-176 package and the ACS9020 transceiver ICs packaged in TQFP-64s.
