Abstract

Systems and methods for testing Optical Network Elements (ONEs) are provided. A process, according to one implementation, includes switching a first broadband switch of a remote ONE from a first output to a second output. The first output of the first broadband switch enables direct transmission to a line-out port configured for connection with a first fiber span of a pair of external fiber spans. The process also includes switching a second broadband switch of the remote ONE from a first input to a second input. The first input of the second broadband switch enables direct reception from a line-in port configured for connection with a second fiber span of the pair of external fiber spans. Switching the first broadband switch to the second output and switching the second broadband switch to the second input enables propagation through a loopback connection for testing the remote ONE.

Dependent claims

An Optical Network Element (ONE) comprising:

a line-out port configured for connection with a first fiber span of a pair of external fiber spans;
a line-in port configured for connection with a second fiber span of the pair of external fiber spans;
a first broadband switch having a first output and a second output, the first output of the first broadband switch coupled directly to the line-out port;
a second broadband switch having a first input and a second input, the first input of the second broadband switch coupled directly to the line-in port;
a loopback connection arranged between the second output of the first broadband switch and the second input of the second broadband switch;
a second line-out port configured for connection with a first fiber span of a second pair of external fiber spans;
a second line-in port configured for connection with a second fiber span of the second pair of external fiber spans;
a third broadband switch having a first output and a second output, the first output of the third broadband switch coupled directly to the second line-out port;
a fourth broadband switch having a first input and a second input, the first input of the fourth broadband switch coupled directly to the second line-in port;
and
