TCR801

 

Optical Clock Recovery Instrument

The TCR801 Optical Clock Recovery is a dual band clock recovery instrument centered around 26 and 53 GBd. The advanced architecture of the TCR801 allows the user to adjust Phase Lock Loop (PLL) bandwidth to comply with standards, and is a crucial component in the test and validation of the optical designs when used with other testing and measuring instruments.

Applications

Key features

  • Designed to lock in two ranges:
    • 25.6 to 29 GBd PAM2/NRZ or PAM4
    • 51.2 to 58 GBd PAM2/NRZ or PAM4
  • 1250 nm to 1650 nm wavelength
  • Adjustable PLL bandwidths to configure the Golden PLL response required for the standard compliance testing
  • IEEE Ethernet Control Interface, which runs the instrument remotely over the network using the stand-alone PC software or through PI using VISA/Tek-VISA.
  • Provides two separate RF clock outputs
  • Intelligent auto relock capability and manual relock functionality is available on the front panel of the instrument
  • 2 x 20 LCD is used to view network IP address and current lock status, including the measured symbol rate

Applications

  • Design/Verification of High-Speed Components and Systems
  • Signal integrity analysis
  • Compliance test for industry standards: 25G, 50G, 100G, 200G, 400G IEEE 802.3 standards such as 400GBASE-FR8, 400GBASE-DR4, and similar optical direct detect standards.

Instrument characteristics

Data interfaces
Single mode, FC/PC connector
Symbol rate coverage
Instrument operates over two nominal ranges (typical operation well beyond these)
  • 25.6 to 29 GBd
  • 51.2 to 58 GBd
Wavelength range
1250 nm to 1650 nm
Data insertion loss
External splitter recommended
  • 50/50% (included)
  • 20/80%
  • 10/90%
Data input power (max)
4 dBm at 1310 nm
Input sensitivity

-10 to 4 dBm at 1310 nm (typical, OMA) with PRBS13Q or similar

- 8 to 4 dBm at 1310 nm (typical, OMA) with PRBS31Q, SSPRQ or similar

Conditions

  • PAM4 modulated signal with TDECQ < 3.4 dB. Sensitivity at higher TDECQ might be lower depending on signal distortion.
  • OR PAM2/NRZ modulated signal passing 100GBASE-LR4 specification using pattern such as PRBS31 or other patterns with same or higher edge density.

 

Counter accuracy
+/- 10 ppm (typical)
