New 10-Gbit/sec DFB laser diode module features integrated EA modulator
June 28, 2002--California Eastern Laboratories (CEL) has announced the availability of a new NEC multiple quantum well (MQW) DFB laser diode module featuring an integrated electro-absorption (EA) modulator. Designed for 10-Gbit/sec transmission of up to 40 km over standard singlemode fiber, the new NX8560LJ-CC is designed for DWDM systems and wavelength selection according to ITU-T G.692 (the full C-Band).
Monolithically integrating the EA modulator saves space and simplifies a system's design. It also lowers cost and consumes less power than a discrete CW/modulator design. Among other features, the NX8560LJ-CC offers high optical output performance with low modulation voltage and low threshold current. Specifics include:
- Pf Output Power (under modulation): -1 dBm min
- VMOD Modulation Voltage: 3 V max
- ITH Threshold Current: 20 mA max
- Wavelength: ITU grid
