P. May et al., IMPROVEMENT IN BIT-ERROR RATE FOR OPTOELECTRONIC MULTICOMPUTER INTERCONNECTION NETWORKS USING CYCLIC REDUNDANCY CODE ERROR-DETECTION, IEEE photonics technology letters, 9(6), 1997, pp. 848-850
This letter presents testing results of an integrated optoelectronic (
OE) channel employing hop-by-hop error control circuitry based on cycl
ic redundancy codes (CRC) to improve the effective bit-error rate (BER
). The use of OE interconnect in place of wires in multicomputer netwo
rks becomes more attractive as channel bandwidth and power efficiency
are increased, But these improvements must be accomplished while maint
aining an acceptable channel BER. Test results of an integrated OE cha
nnel incorporating CRC-based error control circuitry demonstrate a BER
reduction of two orders of magnitude while incurring a 20% bandwidth
overhead, This may lead to higher bandwidth and higher efficiency OE i
nterconnects.
