Request InfoLumexLumex Inc. has introduced two Bellcore-compliant 1310-nm laser diode modules for communications applications. The devices can operate at high ambient temperatures without a thermoelectric cooler. They feature InAlGaAs/InP die composition and a built-in monitor photodiode and are available with either a flat window or a ball lens cap to match the optical fiber. They have a maximum of 10 mW of optical output at 25 °C and a minimum of 5 mW across the entire -40 °C to +85 °C operating and storage temperature ranges.
