10Gbps Full Rate 10Gbps CDR Clock Recovery Module 0.155~11.3G

When sampling oscilloscope tests optical eye pattern and waveform, it needs to be triggered by the same source as the measured signal. CDR (clock recovery) module is mainly used in the test environment that requires sampling oscilloscope to test optical eye map, but does not provide trigger clock. Typical application is the test of optical network equipment, or for BOB products in PON application, because the measured optical equipment itself does not have a frequency division clock output. The clock signal needs to be recovered to trigger the sampling oscilloscope when testing the optical eye pattern.

This CDR is equipped with an SFP optical port, which can be connected to the conventional SFP, SFP+, OLT SFP and other optical modules encapsulated in SFP. Only the receiving end of the optical module is needed, which is responsible for converting optical signals into electrical signals, and then the instrument extracts and outputs the clock of electric signals. The clock signals are mainly used for triggering signals of oscilloscope.

Main parameters of CDR:

1. Clock recovery range: 155Mb/s to 11Gb/s;

2. Wavelength range: 800-1600 nm;

3. Optical input range: +3 ~ -15dBm;

4. Output recovery electric clock (4 frequency division) range: 38.75MHz to 2.78GHz;

5. Output clock amplitude: AC Couple/ 800mVpp in typical;

6. Spectral ratio (can be selected according to the user) : 10% (CDR) -90% (Output)
