NEC's NX8510UD is a 1 470 to 1 610 nm Multiple Quantum  
Well (MQW) structured Distributed Feed-Back (DFB) laser  
diode TOSA (transmitter optical sub-assembly) with InGaAs  
monitor PIN-PD in a receptacle type package designed  
for SFF/SFP transceiver with LC duplex receptacle. This  
device is ideal for 2.5 Gb/s CWDM application.
