Tektronix 80C01-CR

The 80C01 module supports conformance testing of long wavelength (1100-1650 nm) signals at 622, 2488, and 9953 Mb/s as well as general purpose testing up to 20 GHz optical bandwidth. Bandwidth and reference receiver calibration is performed with a sub-picosecond optical impulse and a fourier transform method.

• OC12: The electrical sampler is adjusted to approximately 7.5 GHz (--3 dB) bandwidth and signal is routed through a hardware filter designed to result in the combined system having an OC12 (STM-4) Reference Receiver response.
• OC48: The electrical sampler is adjusted to 7.5 GHz (--3 dB) bandwidth and signal is routed through a hardware filter designed to result in the combined system having an OC48 (STM-16) Reference Receiver response. These adjustments must be made at the factory.
• OC192: The electrical sampler is adjusted to give the desired response, and signal is not routed through any filter (signal is sent through the straightthrough path). The sampler bandwidth and response is optimized during the calibration such that the combined system will have an OC192 (STM-64) Reference Receiver response.
• 12.5 GHz: The sampler bandwidth and response is set during the calibration such that the combined system will have an Optical Bandwidth (--6 dB) >12.5 GHz.
• 20 GHz: The sampler bandwidth and response is set during the calibration such that the combined system will have an Optical Bandwidth (--6 dB) >20 GHz.
