(914 m m) diameter, tight-buff- ered outer jacket. the standard length is 39 in. 4 in. (1 m 10 cm) and can be terminated with either an sc or fc/pc optical connector. other connector options may be available on special order. please contact your lucent technologies account manager for ordering information. table 1. pin descriptions * laser back-facet and bias monitor functions are customer-use options that are not required for normal operations of the transmit- ter. they are normally used during manufacture and for diagnos- tics. ? pins designated no user connection (nuc) cannot be tied to ground or any other circuit potential. pin number name 1v ee 2 bf monitor * 3 bias monitor* 4 tx disable 5 clock select 6 ground 7 nuc ? 8 nuc ? /laser degrade alarm (future option) 9 nuc ? 10 nuc ? 11 ground 12 v ee 13 v cc 14 nuc ? 15 ground 1 6 data 17 ground 18 d a t a 19 ground 20 clock 21 ground 22 cloc k 23 ground 24 v cc
