Fiber Optic Amplifier by QPhotonics

Note: Your Quotation Request will be directed to QPhotonics.

The QSOA-371 from QPhotonics is a Semiconductor Optical Amplifier (SOA) that operates at a wavelength of 840 nm. It has a tuning range of up to 60 nm and operates in two modes: SLD mode (angled fiber cleave) & laser mode (normal fiber cleave). The SLD-mode SOA delivers an output power of 1 mW and has a spectral width of 50 nm. This SOA has a forward current of 65 mA and residual spectral modulation of 3 %. The laser-mode SOA delivers a maximum output power of 10 mW, has an external slope efficiency of 0.4 mW/mA, and requires a threshold current of 40 mA.

The QSOA-371 has a built-in thermistor and thermoelectric cooler that requires a maximum voltage of 3.5 V. It consumes 1.2 A of current and has a forward voltage of 1.8 V. This SOA supports optional FC/APC connectors and uses SM or PM fiber pigtails. It has a traveling-wave MQW design and is available in a hermetically sealed butterfly package or DIL package.
