With SC/PC connector on 900um buffered fiber. Ac-coupled output according to the datasheet of 1st pdf link below. Model 2860E is same as model R2860E (prefix “R” means receiver in Lucent/Agere products) Made in March 2001 or Dec. 2000. With actual manufacturer test sheet (see last three pdf links below) Description The R2860E receiver module incorporates a highspeed planar PIN diode and a GaAs PHEMT preamplifier to provide exceptionally high performance. The unit provides high bandwidth and sensitivity to operate with long, dispersive fibers, plus wide dynamic range for operation over a variety of loss budgets. High transimpedance coupled with a nonquantizing limiting buffer output provides high gain while limiting the maximum output signal swing, thereby simplifying the interface to subsequent stages. Features High sensitivity, –20 dBm typical Wide dynamic range, 2 dBm overload typical High transimpedance, 1200 W typical Hermetically sealed Optimized for multiple supply voltages, including +/-5 V dual supplies, 8 V only, or –8 V only ac-coupled output Applications 10 Gbits/s short, intermediate, and long-haul systems SONET/SDH equipment Datacom equipment
