Abstract: An optical networking unit includes a plurality of optical components mounted on a substrate composed of a material transparent to radiation in a frequency range. At least one of the optical components is secured to the substrate by a curable bonding material of a type curable in response to exposure to radiation in said frequency range. One optical component preferably comprises an optical fiber secured to an optical fiber holder holding the optical fiber and secured to the substrate. An active optical component is optically aligned with the optical fiber and is secured to an active optical component holder holding the active optical component and secured to the substrate.

Abstract: A passive optical network which is capable of full duplex digital transmission at high data rates and which also provides analog broadcast transmission is disclosed. A central station provides analog broadcast transmission at a first wavelength of light and full duplex digital transmission using second and third wavelengths of light. Optical networking units, electrically or wirelessly coupled to end users in the network, are optically coupled to the central station via passive optical network nodes. The optical networking units resolve the two broadcast streams from the central station employing compact optics configured on a transparent substrate and provide burst mode digital transmission up stream to the central station on a time division multiple access basis.
