10G Clock Recovery Unit CR4201

The sampling oscilloscope needs to be triggered by the clock when testing the optical eye diagram. However, in some cases, such as typical ONT testing or line card testing, only the optical signal is output, and There is no clock output, in this case, the CR4201 can recover the clock from the optical signal and provide it to the sampling oscilloscope for eye-diagram testing.

Semight CR4201 has the characteristics of fast locking, low jitter output, rate adaptation, etc. It is widely used in optical modules, optical modem and other test scenarios.
