US Patent:

8180216, May 15, 2012

Filed:

Dec 20, 2007

Appl. No.:

11/961702

Inventors:

Tiejun J. Xia - Richardson TX, US
Glenn A. Wellbrock - Wylie TX, US
Michael D. Pollock - Sachse TX, US

Assignee:

Verizon Patent and Licensing Inc. - Basking Ridge NJ

International Classification:

H04B 10/00

US Classification:

398 25, 398 16

Abstract:

A device for measuring optical latency in a test path includes an optical source to generate an optical signal. An optical modulator modulates the optical signal based on a modulation signal. An output port outputs the modulated optical signal to the test path. An input port receives a return optical signal following propagation through the test path. Latency calculating logic calculates the optical latency for the test path based on the modulation signal and the return optical signal.

International Classification:

G01R 31/08

US Classification:

370241, 324539, 174 33, 174113 R, 370242, 370247, 370249, 370251

Abstract:

An Ethernet cable used with an Ethernet test-set allows a single connection to an Ethernet port of a network element while maintaining individual connections to separate ports on the test-set. The far-end of the signal path is a single Ethernet cable port having its transmit and receive pins interconnected. The far-end port interconnections cause a test signal which has traveled to the far-end port to be returned to the test-set and to be receive in a test-set port other than the originating port Two signal paths can be simultaneously tested with the same test-kit. Interconnections between the test-set ports by way of the cable maintain a “no-signal”alarm disabled, which otherwise would be energized because there is no signal being received in the port from which the test signal originated.
