Data Rate Range

25.6 to 29 GBd
51.2 to 58 GBd


1250 nm to 1650 nm

Loop Bandwidth

0.2 MHz to 10 MHz

Designed to support compliance testing for a growing range of standards

The TCR801 supports 25G, 50G, 100G, 200G, and 400G IEEE 802.3 standards as well as high speed standards like NRZ 100 Gb Ethernet operating at a rate of 25.78125 Gb/s and 32 GFC. With standards requiring clock recoveries for compliance, the TCR801 provides a simple and efficient way to support fast and accurate measurements for a variety of standards including PAM4 400GBASE-FR8 and 400GBASE-DR4.

Data rate ranges include:

  • 25.6 to 29 GBd PAM2/NRZ or PAM4
  • 51.2 to 58 GBd PAM2/NRZ or PAM4
  • Operation beyond 29 or 58 GBd is supported with lower sensitivity (see datasheet for details)

Adjustable Phase Lock Loop bandwidths

Standards require the use of a golden PLL for compliance testing. You can rely on the TCR801 to recover the clock from your data pattern in accordance with IEEE 802.3 or similar required loop bandwidth and be confident you’re in compliance with the appropriate standards.
