Description:

LFO-18/2-ip – is the optical module on the base of uncooled 1,55

μm MQW

InGaAsP/InP Fabry-Perot Mitsubishi laser diode, coupled with singlemode

optical fiber. Hermetically sealed modules are performed in standard

packages with built-in InGaAs monitor photodiode and collimating

gradient microlens. The modules operate in wide temperature range, have

LFO-18/2-ip – is the best source for digital (up to 622 Mb/s)

telecommunication lines, optical testers and other metrology devices, local

optical networks and many other applications.
