12 GHz Fiber-Optic Receivers

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.

Visible and NIR versions
Switchable DC-coupled or AC-coupled output versions
Singlemode and Multimode fiber connector options
Ultra-clean pulse response
Ideal for characterizing OC-192 and 10-GbE components

Features

GaAs and InGaAs Versions

Model 1580-B utilizes a GaAs diode providing wavelength coverage from 780-870 nm, with a higher sensitivity at 850 nm than the 1544 models, popular for datacom, optical sensing, imaging, LIDAR, and time-of-flight measurements. Model 1544 utilizes an InGaAs diode to provide broad spectral coverage from 500-1630 nm for singlemode fiber and 780-1630 nm for multimode fiber.

Switchable DC-Coupled or AC-Coupled Output

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.

Ultra-clean Pulse Response

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.

NOTE: Pulse response measured on a 20-GHz oscilloscope with a 100-fs optical pulse. Step response calculated from pulse response.

Applications

Applications for these photoreceivers include:

Characterizing 10-Gbit/s components, including BER testing and generating eye diagrams
Characterizing the frequency or time responses of pulsed lasers, modulators, and transmitters
Characterizing pulse propagation through dispersive optical systems
RIN measurements
Heterodyne experiments
Precision timing/triggering

Singlemode or Multimode Fiber

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.
