Bit Error Ratio Tester 8x56G PBT8856

Bit Error Ratio Tester 4x25G MBT5210
Bit Error Ratio Tester 8x112G PBT8812

With the rapid development of the network, more and more applications need more band support. 400G has become the demand for the upgrading and expansion of the backbone network. Pbt8856 can support 8-channel PAM4 signal with parallel transmission, and has been widely used in 400g optical module and optical device test.

Notes：
① The measured value is the net output value of the transmitter, the default pre-emphasis/de-emphasis parameters;
② 30cm RF test cable, output measured value in “high power output” mode;
③ Measured with 26.5625 Gb/s NRZ signal;
④ Measure random jitter after jitter separation;
⑤ The measured value is the net input value at the receiver;
⑥When the input amplitude is less than 100 mVpp, the corresponding bit error rate may reach e-3 or even LOS;
