Product Overview:

These 1550nm laser diodes manufactured by Fibercom offer 20mW of optical output power. These devices are single mode lasers and ship in an industry standard TO-18, 5.6mm hermetically sealed TO-can package. These affordable devices are perfectly suited to high volume industrial applications or for R&D lab applications. Extensive characterization and testing can be seen in the well defined tuning derivative specifications. All of these diode lasers are burn-in tested at the factory prior to shipment and come with an LIV plot.

These devices are designed to operate at a case temperature of ~ 25 degrees Celcius. Because they do not include and integrated TEC controller, it is recommended that the user provide a stable temperature controller heat sink or TO-can socket which is thermally stabilized. These 1550nm lasers do offer an integrated monitor photo-diode. The monitor diode can be used to set the laser in a constant power mode of operation. The MPD has an output range of 1 to 1000 microamps.
