QDFM-010

The QDFM-010 is designed as pinFET module which contains a GaAs integrated circuit preamplifier and circuitry used to control its effective transimpedance. The use of GaAs IC, with its associated large values of gain bandwidth profuct, makes it possible to change the gain / transimpedance of the amplifier while ensuring complete stability over a broad range of transimpedance values. For the low optical inputs, The QDFM is operated as a conventional transompedance pinFET with the transimpedance value chosen to be as large as possible (for high sensitivity) while providing a bandwidth adequate for the intended data rate.

Some absolute maximum ratings of QDFM-010 have been concluded into several points as follow. The first one is about its fiber coupled power which would be 5mW. The next one is about its reverse photocurrent which would be 5mA. The next one is about its reverse bias voltage which would be 15V. The next one is forward current which would be 2mA. The next one is about its lead soldering temperature which would be 260°C. Th next one is about its lead soldering duration which would be 10 sec. The next one is about its fiber yield strength which would be 10N min. The next one is about its fiber bend radius which would be 35mm min.

Also some specifications about QDFM-010. The first one is about its sensitivity change 25°C to 65°C which would be 1.5dB. The next one is about its delector dark current which would be typ 5nA and max 20nA. The next one is about its detector capacitance - 5V bias which would be typ 0.3pF and max 0.5pF. The next one is about its load impedance which would be typ 1000 ohms. The next one is about its output voltage at Pmax which would b typ 1V. The next one is about its measured output impedance which would be typ 50 ohms. And so on. For more information please contact us.
