A modular Cable Modem Termination System (CMTS) includes a packet shelf operating a Data Over Cable Service Interface Specifications (DOCSIS) Media Access Control (MAC) framer. One or more downstream Physical Interface (PHY) shelves receive DOCSIS data from the packet shelf over a packet switched network and modulate the DOCSIS data for sending on a downstream path of a cable plant. One or more upstream PHY shelves send DOCSIS data received from an upstream path of the cable plant over the packet switched network to the packet shelf. By separating the PHY components from the MAC and from the system software, the PHY components for a Hybrid Fiber Coax (HFC) plant may be replaced with different PHY components for other access technologies such as wireless, Digital Subscriber Lines (DSL), Ethernet-to-the-Home, Fiber-to-the-Home, or fiber Passive Optical Networks (PONs).

The subject matter disclosed herein relates generally to the production of a predetermined ratio of multicomponent fibers in combination with monocomponent fibers or other multicomponent fibers, preferably through a spunbonding process. After extrusion, these fibers can produce a fiber network that is subsequently bonded to produce a nonwoven fabric comprising multiple types of fibers. The multicomponent fibers within the network may be processed to remove one component by dissolution or to split the individual components into separate fibers. As a result, the fabric will be comprised of fibers with a range of diameters (micro- or nano-denier fibers as well as higher denier fibers) such that the fibers will not pack as tightly as in a homogeneous nonwoven fabric produced from one type of monocomponent or multicomponent fiber. The present invention additionally relates to methods for producing nonwoven fabrics with increased loft, breathability, strength, compressive properties, and filtration efficiency.

A hybrid, wide angle imaging system combines high sensitivity superposition arrays with a high resolution apposition array to generate distortion free images with an infinite depth of field. A conformal, superposition array of Keplerian telescope objectives focuses multiple apertures of light through the tubes of a louver baffle. The baffle tubes are terminated by field stops that separate the focused light into inverted, intermediate sub-images. A superposition array of field lenses, positioned immediately after the field stops, reverses the angles of the light beams. An apposition array of erector lenses, linked optically to the superposition arrays and field stops, refocuses and adjoins the beams into a single, upright image. The upright image is formed on the convex surface of a fiber optic imaging taper, which transfers the image to the flat bottom of the taper where it can be viewed through an eyepiece or digitized by a detector array.
