The PGT 20406 10Gbps EML module from Ericsson Microelectronics combines a continuous wave DFB laser with an electro-absorption modulator, enabling it to transmit optical signals at distances of up to 80km.

Designed for DWDM, SONET/SDH, and 10Gb Ethernet networks, the device offers a modulator chirp that results to dispersion penalty <2dB over 80km (1.6ns/nm) in a standard single mode fiber, allowing the module to be used in long reach applications.

The laser module has an RF extinction ratio >10dB and is available with ITU-T wavelengths over the entire C-band range (1,530nm to 1,563nm). The PGT 20406's high bandwidth enables data rates up to 10.7Gbps and can be used in systems with FEC capability.

The module comes in 7-pin butterfly package with standard pinning and a GPO connector, enabling second sourcing and ensuring drop-in compatibility with other 10Gbps EMLs from the company. The package also contains a thermoelectric cooler, thermistor, monitor photodiode, and optical isolator.
