These 12 GHz fiber-optic receivers are ideal for applications that require high sensitivity, high speed, and clean responses. The high gain and gradual, well-behaved roll-off of the frequency response also make them useful for frequency-domain measurements.
-A: AC-coupled models
-B: Switchable DC- or AC-coupled models, 10-kHz cutoff when AC-coupled
Model 1580 utilizes a GaAs diode providing wavelength coverage from 780-870 nm. Model 1544 utilizes an InGaAs diode to provide spectral coverage from 500-1630 nm for singlemode fiber and 780-1630 nm for multimode fiber.
The clean response and 32 ps rise time make these devices especially well-suited for time-domain characterization of 10-Gbit/s components. The high gain and gradual, well-behaved roll-off of the frequency response also make them useful for frequency-domain measurements.
The -B versions of these photoreceivers include a DC-coupled option so they give response all the way down to DC. At the touch of a switch, you can select the traditional AC-coupled output with a 10-kHz cutoff or DC-coupled mode.
In Model 1544-A/B optical signal is delivered to the PIN photodiode through a 0.1 m, 9-um core singlemode fiber, while Model 1544-A/B-50 has a 50/125-µm multimode fiber and Model 1580 comes standard with a 62.5/125-µm multimode fiber.
