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
The 12 GHz photoreceivers 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.
Model 1580 (shown left) utilizes a GaAs diode providing wavelength coverage from 780-870 nm. Model 1544 (shown right) utilizes an InGaAs diode to provide spectral coverage from 500-1630 nm for singlemode fiber and 780-1630 nm for multimode fiber.
Model 1544 has single-mode fiber while Model 1544-A/B-50 has a 50/125-µm core multimode fiber and Model 1580 comes standard with a 62.5-µm core multimode fiber.
Models 15X4-A/B typical pulse and step response (inverted). NOTE: Pulse response measured on a 20-GHz oscilloscope with a 100-fs optical pulse. Step response calculated from 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.
10-Gbit/s data generated with a Model 1544-A or1544-B photoreceiver. Both the photoreceiver and the transmitter contribute to the observed transition times. Because the Models 15X4 are 50% faster than typical 10-Gbit/s photoreceivers, a more accurate measurement of the transmitter response is achieved. NOTE: Eye-diagram performance for the Model 1580-A is similar to that of Model 15X4-A.
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
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.
