... The post-amplifier of the LCP-1250B4QSRB also includes a LOS (Loss Of Signal) circuit that provides a TTL logic-high output when an unusable optical signal level is detected. The LCP-1250B4QSRB transceiver is a Class 1 eye safety product. The optical power levels, under normal operation, are at eye safe level. DELTA ELECTRONICS, INC. ...
