Higher sensitivity InGaAs photodetectors

27 February 2002 Opto-Electronics

Optical time domain reflectometry (OTDR) is a long established technique for determining the type and location of faults in optical fibre. New higher sensitivity InGaAs receivers from Hamamatsu Photonics (series G8370) allow longer distance and higher accuracy fault detection to be achieved.

Hamamatsu offer a range of PIN and PIN + pre-amplifier detectors, either in TO metal cans, in industry standard fibre-optic connectors (such as ST, FC, SC, LC, etc) or pigtailed to standard fibre-optic cable (series G819x, G833x, G834x, G7881).

It also supplies a range of matched FP laser diodes to complement the detectors for data transmission applications (series L8347).

Hamamatsu Photonics, an independent supplier of optoelectronic components, manufactures a wide variety of other components for fibre-optic applications such as silicon PINs and APDs, InGaAs arrays, LEDs, etc.
