1550nm DFB Laser, 10mW, Integrated Electro-Absorptive Modulator 10GB/s EML

Product Overview:

Lucent 1550nm, 10mW DFB Laser, 10 GB/s EML Laser:

The E2560 DFB laser diode with an integrated electron-absorptive modulator is designed for 10 Gbits/s DWDM transmission applications. It offers an integrated CW laser diode with an electro-absorptive modulator on the same semiconductor chip. These DFB lasers are packaged in a 7-pin butterfly with a small-profile Gilbert GPO connector for the RF signal input. In WDM systems, these devices are typically coupled into an erbium-doped fiber amplifiers in order to ensure that sufficient optical power reaches the receiver. These devices can replace external modulators which are often bulkier, more expensive, and require more complex drive electronics than an EML. Both the E2560 and E2580 models are available for transmission distances of 40 km and 80 km. The package also contains a thermoelectric cooler, thermistor, rear facet monitor photodiode, and an optical isolator.

Note on Proper Handling and Operation of Laser Diodes:
Laser diodes are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
