With its single-mode, eSFP form factor and 1310nm wavelength, this transceiver supports 1. 25Gb/s data rates over distances of up to 10km. It's engineered to perform reliably, ensuring optimal signal transmission with a transmit power range of -9 to -3dBm and a receiver sensitivity of. In optical communication systems, sensitivity is a measure of how weak an input signal can get before the bit-error ratio (BER) exceeds some specified number. The standards body governing the application sets this specified BER. It's engineered to perform.
