The most challenging technical requirement for the new 100GBASE-LR4 and ER4 interfaces is optical transmitter compliance testing. The compliance test requirements of the optical transmitter transmit waveform (eye diagram) include the need for a new reference receiver and the use of a standard clock recovery unit (CRU). 0.75 x 25.78125 Gb / s), the clock recovery unit should have 10 MHz PLL loop bandwidth and -20 dB / decade roll-off characteristics. 
Tektronix provides a powerful and versatile solution based on the DSA8200 digital serial analyzer sampling oscilloscope and 80C10B optical module to meet the new 100GBASE-LR4 and ER4 transmit waveform compliance test requirements. When equipped with options F1 (25G and 40G filter filtering options) and CRTP (40 + Gb / s clock recovery trigger holdoff option), it can drive the input of the Tektronix CR286A 28.6Gb / s clock recovery instrument to ensure standard clock recovery The function and the guaranteed optical reference receiver meet the telecommunication standards and data communication standards from 25.7 GHz to 44.5 GHz in one module. 
The solution provided by the DSA8200 with 80C10B module achieves the lowest optical noise, the best signal fidelity, 200 fsec RMS jitter (with 82A04 phase reference module) and outstanding measurement throughput. 
The CR286A clock recovery instrument continuously covers data rates from 150 Mb / s to 28.6 Gb / s, providing a perfect “standard PLL†for transmitter and receiver compliance testing, including all previous serial standards and the latest and ongoing Proposed serial standards such as 100GBASE-LR and ER-4, CEI-25G-LR, CEI-28G-SR, 6xFC and future 28xFC (28.050 Gb / s). 
CR286A independently controls, measures and displays PLL loop bandwidth (200 kHz-12 MHz, optional 24 MHz), peak value and JTF (jitter transfer function), 25.78125 Gb / s 100 GBASE-LR-4 and CEI-25G-LR And 28.050 Gb / s CEI-25G and CEI-28G-SR conformance transmitter eye diagram, jitter measurement and receiver stress test calibration provide "standard PLL" response.
