Organization: ITU-T
Publication Date: 1 May 2007
Status: active
Page Count: 20
scope:

This Recommendation mainly describes the maintenance band and requirements for maintenance test light filtering (such as cut-off bandwidth, isolation and other optical characteristics) for testing in-service fibre lines without interfering with optical communication signals in access networks.

This Recommendation provides guidance on the use of an out-of-band remote test system. An alternative approach is to monitor key parameters of the transmission equipment, such as the OLT transmitted power and the ONU received power, but this approach is not examined in this Recommendation.
