Optical Networking Unit Transceiver
EMCORE Corp.
The Radio Frequency Over Glass (RFoG) Optical Networking Unit (ONU) Transceiver from Emcore Corp. is an optical beat interference mitigated design utilizing the company's Linear Externally Modulated Laser (L-EMLTM). The FoG ONU Transceiver is designed to support standard CATV downstream and upstream transmission bands for triple-play voice, video and data signals in single-family and multiple-dwelling unit applications. Downstream it receives a 1550-nm forward path optical signal carrying a radio frequency cable television spectrum up to 1.2 GHz, making it compatible with the...See full product
