KISTA, Sweden -- Leading supplier of optoelectronic devices Northlight Optronics has released a high output, 10Gbps laser transmitter with a transmitting capability of up to 80km aimed at SDH/SONET, DWDM and 10GbE applications.Northlight's PGT20456 DFB/EA laser module combines a continuous wave DFB laser with an electro-absorption modulator in a single chip. It is designed to transmit optical signals in both long haul and metro applications in single channel or dense wavelength division multiplexing (DWDM) optical networking equipment.With its integrated modulator, the laser provides a cost-effective on-board solution. It is aimed at both OEMs producing optical networking systems, and manufacturers who build subsystems such as transponders.The standard node/link distance in existing 2.5Gbps systems is 80km. Using the PGT20456 it is possible to replace four 2.5Gbps lasers with one laser, without changing the distance between the nodes. This provides the option to reduce the number of lasers (increasing reliability), and/or increase the transmission capacity in the systems.As a former Ericsson company, Northlight Optronics has called upon its long experience (20 years) in opto chip design and component packaging to develop the improved 10Gbps laser. The PGT20456 has excellent modulator chirp performance, offering a low dispersion penalty allowing its use in long reach applications. The laser is drop-in compatible with other Northlight 10Gbps DFB/EAs, so no board redesigns are necessary to incorporate it into existing board designs. The device is also compatible with other vendors' parts. Northlight Optronics AB
