This makes it suitable for applications requiring high signal quality, such as telecom networks, CATV systems, and optical sensing.

The laser delivers an optical power of 6-8mW, optimized for reliability in continuous operation. It features a built-in thermoelectric cooler (TEC) to maintain temperature stability. This minimizes wavelength drift and ensures consistent performance across varying environmental conditions. The module supports data rates up to 2.5Gbps, compatible with standard communication protocols.

The device includes a single-mode fiber pigtail, pre-connected to simplify integration. Connector options include FC/APC or SC/APC, reducing installation time. Polarization-maintaining fiber is available for applications requiring precise polarization control. An internal monitor photodiode tracks output power, enabling real-time feedback for automatic power control (APC) circuits. This protects the laser from damage due to overcurrent or temperature fluctuations.

Electrical interfaces use industry-standard pins for easy connection to drive circuits. Operating voltage ranges from +5V to +12V DC, depending on configuration. The module operates within a temperature range of -10°C to +60°C, with storage conditions of -40°C to +85°C.
