FU-318AP-M6/FU-318SAP-M6
InGaAs APD MODULE FOR LONG WAVELENGTH BAND
DESCRIPTION
Th e FU-318AP-M6 /318SAP-M6 series avalanche
photodiode(APD) modules are designed for use in
fib er testing equipment and high-speed, long haul
optical communication systems.
Th e coaxial pakage contains an InGaAs APD coupled
into either singlemode or multimode fiber pigtail.
FEATURES
High-responsivity (0.8A/W at 1300nm)
High-speed response (fc=3GHz)
APPLICATION
Fiber testing equipment(OTDRs)
Long haul optical communication systems
