During 2017, 2018, and 2019, COTSWORKS manufactured over 50,000 of the SFF style 802.3 BX standard WDM optical transceivers. The average Tx power was -12.06 dBm with 95.08% of final tested product having a variability less than 1.5 dB from mean and 99.77% measuring less than 3 dB from mean. The transceivers’ RX sensitivity measured at an average of -38.89 dBm with 86.97% having less than 1.5 dB variation from mean and 97.44% with less than 3 dB from mean. These results include 100% parametric temperature testing and conformal coating. COTSWORKS is pleased to share the positive test results with its customers and the rugged opto-electronics community!
