The 1544-B-50 DC-Coupled NIR Fiber-Optic Receiver is ideal for applications that require high sensitivity, high speed, and clean responses. It offers clean responses and 32-ps rise times making it well-suited for time-domain characterization of 10-Gbit/s components. Its high gain and well-behaved frequency response also make it useful for frequency-domain measurements. For higher responsivity from 800-1650 nm, this photoreceiver has a 50 μm core multimode fiber input and consists of our new, improved InGaAs PIN photodiodes followed by a GaAs HBT amplifier.
An external power supply, which must be purchased separately, is required – we recommend our

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-B comes standard with a 62.5/125-µm multimode fiber, which can accept laser light from both the 50 and 62.5 µm core fiber.
