CEL unveils 2.5-Gbit/sec DFB LD module
May 17, 2002-- California Eastern Laboratories (CEL) has developed a new DWDM Multiple quantum well (MQW) DFB laser diode module featuring an integrated electro-absorption (EA) modulator. Developed for 2.5-Gbit/sec transmission, the new NX8566LE-CC is capable of a reach of over 240 km. Designed for DWDM ITU-T-based wavelengths (full C and L Band coverage), the new NX8566LE-CC is ideal for metro and long-haul applications, says the company.
Monolithically integrating the EA modulator saves space and simplifies a system's design. It also provides a solution that's lower cost and consumes less power than a discrete CW/modulator design, according to CEL. Among other features, the NX8566LE-CC offers high optical output power from fiber under modulation with a very low dispersion penalty. Specifications include:
- Pf Output Power (under modulation): 0 dBm.
- VMOD Modulation Voltage: 3 V max.
- ITH Threshold Current: 20 mA typical.
