Common use of End-to-End Testing Clause in Contracts

End-to-End Testing. After the contractor has provided end-to-end connectivity on the fibers, bi-directional end-to-end testing will be done. Continuity tests will be done to verify that no fibers have been "frogged" or crossed in any of the splice points. Loss measurements will be recorded using a laser source and a power meter. OTDR traces will be taken and splice loss measurements will be recorded. The Constructing Party will also store OTDR traces on diskette. A. It is imperative to verify that all fibers have one-to-one continuity on the new cable. This should be done at the fiber level, not just the pigtail level. For each pigtail, a HE-NE laser will be used to verify fiber color and buffer tube color. Once the fiber color and buffer tube color have been recorded, a laser light source will be attached and a power meter reading will be taken at the far end. Then at the far end, a HE-NE laser should be used to verify the fiber color and the buffer tube color of the fiber receiving the light. Then power level readings should be taken in the opposite direction. The power measurements should be made at both 1310 nm and 1550 nm. B. OTDR traces should be taken in both directions at both 1310 nm and 1550 nm. Loss measurements for each splice point should be measured and recorded in both directions. These loss values should then be averaged. The traces for all fibers should be recorded on diskette and provided to the other party.
