PRBS7 Tunable Laser Source 400G PM4 BERT Error Code Tester Independent Or Eight Way Synchronous Test
400G PM4 BERT Error Code Tester Independent Or Eight Way Synchronous Test
Performance characteristics:
1. Signal coding mode: NRZ and PAM4, which can automatically switch freely between NRZ and PAM4 signals.
2, eight-channel synchronous output, used to test 6.144G, 10G, 40G, 100G, 200G and 400G products, error test can be independent or eight-channel synchronous test.
3, Support continuous error detection and timing error monitoring, support KP4/KR4 hardware FEC function.
5, the clock frequency of the default 4 frequency division, support a quarter, 1/8, 1/16, 1/32, 1, 64, 1 / frequency than 128 points.
6,Communication mode: USB to HID. No driver is required. The PC upper computer software communicates with the device to set the bit error meter and test the bit error rate.
