Passive components in the subscriber loop

Abstract

Excellent progress has been made over the past few years in the area of passive components for optical fiber subscriber loop systems. The key functional requirements of interconnection, furcation, and filtration currently are being met by discrete components that can be manufactured in sufficient volume to carry forward the trials currently in progress or being planned. Depending on system architecture, the cost and ease of use of these components can play a pivotal role in allowing fiber deployment in the distribution loop to proceed. Ultimately, discrete components will he displaced by more highly integrated components and finally by fully integrated optoelectronics over the next several decades.

Novel splicing technique for coated optical fiber connection without stripping or cleaning process

“…Many optical fiber connection techniques have been developed and used in fiber to the home systems including fusion splices, mechanical splices, and both factory assembled and field installable connectors [1–3]. In addition, a variety of optical fiber interconnection techniques have been deployed for wiring between optical devices in various devices [4, 5].…”

Modeling multimode-input star couplers in polymers

“…Due to their ease of fabrication [1]- [3], assembly, and fiber-optic alignment, polymer-based star couplers which are multimode in the input/output waveguides can provide a cost-effective alternative to single-mode devices. Multimodeinput star couplers have been used in local multicast networks [4], [5] in optical interconnect systems for backplane wiring, on-board chip-to-chip or intramainframe computer connections [6]- [9], and in optical sensor systems (fly-by-light) [lo].…”

Optical Performance Analysis of Single-Mode Fiber Connections

“…Many single-mode optical fiber (SMF) connection techniques, such as fusion splicing, mechanical splicing, and use of optical connectors, are currently used in fiber-to-the-home (FTTH) systems (Keck et al, 1989;Shinohara, 2005). A fusion splice is fabricated by a fusion splice machine (splicer), which is a precision machine containing fiber alignment, video monitor, and arc discharge functions; it has the highest and stablest performance of all the connections.…”
