Optical Communications

Whether you work on optical components, transceiver subassemblies or transmission systems, there are critical PHY layer tests necessary to execute: eye diagrams and jitter performance, stressed receiver testing, crosstalk & BER tests, and optical modulation analysis.  Tektronix provides you with the expertise and equipment to perform standards-compliant TX, RX and Coherent Optical testing from 125 MB/sec to 100 GB/sec and beyond. Tektronix is the only test and measurement vendor that can offer a complete end-to-end testing of coherent modulation formats.

  • DSA8300 Series Sampling Oscilloscopes are suitable for accurate characterization of optical transmitter performance for major single-mode optical standards from 8.5 Gb/s to 44.5 Gb/s and multi-mode from 25.78 Gb/s to 28.05 Gb/s using built-in optical reference receivers and very low OSNR.
     
  • Coherent Optical Test Systems are required to test the latest communication systems for 100G, 400G, 1Tb/s and beyond.
     
  • Optical receiver test standards like OIF-CEI, IEEE802.3bj & Infiniband require jitter tolerance testing. The Tektronix BERT portfolio provides signal conditioning and BER analysis up to 40Gb/s from 1-4 channels. For precise jitter tolerance testing and in-depth impairments & analysis, the BERTScope BSA Series Bit Error Rate Testers provide long pattern generation of PRBS signals along with very accurate BER measurement results and deep, root-cause analysis on >28Gb/sec communications system designs.
     
  • For PRBS patterns that need clean, fast edges and multi-lane generation (MLG), the PatternPro® PPG and PED Series single and multi-channel Pattern Generators and Error Detectors are ideal simultaneous BER testing of up to four lanes at 32Gb/s, and patterna generation and error detection capability at 40Gb/s.
