The optical transceiver module is a duplex LC connector designed to provide an IEEE C37.94 link for 2Mb/s applications. It provides up to 20km transmission distance over single-mode fiber at nominal wavelength of 1310nm. It is with the SFP 20-pin connector to allow hot plug capability. All the transceivers comply with the SFP MSA, SFF-8472, CE, FCC, RoHS, and corresponding industry standards.
