Common use of OTDR TESTING Clause in Contracts

OTDR TESTING. (a) Grantor will conduct optical time-domain reflectometer (“OTDR”) testing at both 1310 nm and 1550 nm wavelengths when the Buyer Fiber consists of Standard Single Mode Fiber, and at 1550 nm if the Buyer Fibers consist of either Dispersion Shifted Fiber (TrueWave™, LEAF™, etc.) or a combination of Single Mode and Dispersion Shifted fiber types. Grantor will conduct OTDR testing on a bi-directional basis for each Buyer Fiber in each span. However, if due to length or attenuation reasons the Buyer Fiber span exceeds the OTDR dynamic range, a portion or the entire span may be tested on a unidirectional basis. Alternatively, the Buyer Fiber span may be divided into shorter testing spans, to the extent reasonably possible, in order to obtain bi-directional analysis. Also, in instances where ▇▇▇▇▇ intends to accept Buyer Fibers that are not terminated at one end by Grantor in a fiber distribution panel (such as in a manhole or handhole), only unidirectional testing will be performed. Based on the foregoing OTDR testing methodology, each Buyer Fiber span must meet the following minimum performance requirements, excluding loss associated with splices and connectors: Singlemode at 1310 nm 0.35 Singlemode at 1550 nm 0.25 (b) Grantor will provide a turnover documentation package containing the actual traces detailing the testing parameters (including pulse width, averaging and range). The average bi-directional splice loss for all splices within each span must be
