81495A Reference Receiver

The Keysight Technologies, Inc. 81495A Reference Receiver is an O/E converter optimized for transceiver loop-back test according to IEEE 802.3ae, -LR, -LRM, -ER, -SR and FCx1, FCx2, FCx4, FCx8 and FCx10.

Offering a multimode fiber input, single-mode and multimode signals can be detected. Therefore the module covers the functionality of two modules in one, without extra cost.

The module is fully integrated into the industry standard Keysight Lightwave Measurement System LMS ( 816x A/B ) platform.

Together with the huge range of modules for the LMS, any optical test application can be build within minutes. Remote control can be used to monitor the average optical power of the analyzed signal.

For the transceiver loop-back test the return signal of the transceiver is fed back to the BERT (Bit Error Ratio Tester). As the transceiver output is optical, the signal must first be converted to the electrical domain with the 81495A Reference Receiver.

The performance of this conversion has significant influence on the results of the loop-back test. The 81495A reference receiver works perfectly with the N4917A Optical Receiver Stress Test solution.

As additional feature the reference receiver provides an integrated optical average power meter. The capability of verifying the average optical power of the connected signal with the same receiver as the RF signal offers a fast and simple way to control the average signal power of the tested signal.

Benefits

− Single-mode and multimode O/E in one device provides best cost efficiency.

− Clean eye for best loop-back performance in transceiver test.

− Low noise and low jitter to support reliable O/E conversion for optical stress test.

− Compliance to IEEE 802.3ae -LR, -LRM, -ER, -SR and up to 10 GFC in combination with the N4917A Optical Receiver Stress Test solution.

− Quick signal level verification and diagnosis with integrated average optical power meter.

− Linear conversion with internal amplifier extends the application as frontend O/E converter.

− Seamless integration in the industry standard Keysight LMS platform extends your optical workbench capabilities.

Applications

− Loop-back test for compliance with IEEE 802.3ae optical transmitter stress test.

− Qualitative analysis of modulated signals with an electrical spectrum analyzer or oscilloscope

− Any scientific optical measurement setup that requires O/E conversion up to 9 GHz.
