LFO-18-i
LFO-18-i – is a series of optical modules based on Mitsubishi 1550nm MQW InGaAsP/InP Fabry-Perot laser diode and coupled with singlemode optical fiber. Hermetically sealed modules are performed in standard «DIL-14» package with built-in InGaAs monitor photodiode, thermocooler and thermistor. The modules operate in wide temperature range, have stable output power and more than 5*105 hours of lifetime. LFO-18-i – are the best light sources for digital (up to 622Mb/s) fiber-optic communication lines, optical testers, systems of optical synchronization and other applications.
