The module incorporates 1490nm continuous-mode transmitter and 1310nm burst-mode receiver. The transmitter section uses a 1490nm DFB laser and an integrated laser driver which is desigened to be class-1 eye safe under any single fault. PON (Passive Optical Network), as an access network technology, can implement fiber optic to the home, satisfying the high-bandwidth requirement of the "last kilometer" in the access layer network. The PON technology includes: · Ethernet PON (EPON), a passive optical network based on Ethernet, is. EPON module, defined by the IEEE 802. OMCI-EPON is based on IEEE 802. 1 for user data transport, and applies Annex C of. This contribution is based in part on input from multiple optical component suppliers. Probably will need to cool DMLs for maximum power: assume 5 nm spectrum? With OLT DML, too much dispersion for ONU EDC? It's a new wavelength, and some vendors say that. Passive optical network (PON) technology is a passive broadband access technology that uplinks and downlinks data with different wavelengths, and uses time-division multiplexing technologies for data transmission.
