Inter-Bay Fiber Management Assembly
US Patent:
6571047, May 27, 2003
Filed:
Apr 18, 2000
Appl. No.:
09/551125
Inventors:
Francis R Yarkosky - Kansas City MO
David W. Williams - Olathe KS
David W. Williams - Olathe KS
Assignee:
Sprint Spectrum, L.P. - Overland Park KS
International Classification:
G02B 600
US Classification:
385135, 385137
Abstract:
The illustrated fiber management assembly includes a rectangular case configured to fit between bays of equipment. Fiber connected to the equipment bays enters the case through a top inlet opening and exits the case through one of two outlet openings extending along respective sides of the case, with any excess fiber being located within the storage chamber defined by the case. Adjacent the inlet opening of the case is a clamp that is compressible around the fiber to relieve axial loading on the fiber. The management assembly is provided with a slack take-up mechanism that is configured to support excess fiber in a looped arrangement within the storage chamber. The slack take-up mechanism includes a plurality of spool assemblies adjustably positioned along the length of the storage chamber. Supported for sliding movement along the length of each outlet opening is at least one fiber router designed to support the fiber exiting the storage chamber and limit bending of the fiber as it is directed to the equipment bay.
Arrangement And Method For Testing Fiber Optic Telecommunications Circuits Over Dense Wavelength Division Multiplexing (Dwdm)
US Patent:
2004022, Nov 18, 2004
Filed:
Jun 23, 2004
Appl. No.:
10/874444
Inventors:
Douglas Richards - Stilwell KS, US

Assignee:
SPRINT COMMUNICATIONS COMPANY, L.P.
International Classification:
H04B010/08
US Classification:
398/016000
Abstract:
An arrangement and a method for testing a telecommunications circuit over Dense Wavelength Division Multiplexing (DWDM). A transmitter, which is optically coupled to the circuit, transmits a test-drive signal on the circuit. Through a network, a performance of the circuit is monitored at points along the circuit based on the transmitted test-drive signal.
