The Contractor shall notify the Owner in writing, five (5) calendar days in advance of the testing of the cable, so that the Owner staff may be present for the tests. Test result printouts shall include, but not limited to, the following: a) Distance of trace b) Totalloss c) Splice loss d) Cable ID e) Fiber ID f) Beginning testing location g) Fiber testing location h) Operator/technician name or initials i) Date and time test was performed j) Test wavelength k) Test pulse width 1) Re -factory index The method of connectivity between the OTDR and the tested fiber shall be factory assembled patch cords, pulse suppression, or launch cables equal to length of 150% of the dead zone as published by the OTDR manufacturer. The launch cable shall have the appropriate connectors to allow for connection to the terminated fiber port, without the use of additional couplers. The Contractor shall prepare and submit a test procedure for the pre -installation and post installation tests to the Owner for approval. 7.3 FIRESTOPPING 7.3.1 The Contractor shall be required to firestop all penetrations of floors and walls, including cable "riser" openings.

Construct conduit runs as straight as possible, and obtain the Engineer's/Owner's approval of all major deviations in conduit locations from those shown on the plans. b) Do not place more than the equivalent of four quarter bends or 360 degree of bends, including the termination bends, between the two points of termination in the conduit, without a pullbox. Obtain the Engineer's/Owner's approval to use corrugated flexible conduits for short runs 6' or less. c) Use only intermediate metal conduit, rigid galvanized conduit, rigid aluminum conduit or PVC coated intermediate metal conduit for above -ground or underground electrical power service installations. d) Use either schedule 80 PVC or fiberglass reinforced epoxy conduit for installations on bridge decks. Use either schedule 40 PVC or fiberglass reinforced epoxy, conduit for underground and under pavement installations, except for electrical power service. e) When the installation of a conduit requires jacking under paved surfaces, railroads, etc., use an intermediate metal conduit as the sleeve for the underground conduit. Install the underground conduit as shown in the Design Standards, Index No. 17721. 23
