OTDR TESTING Clause Samples

OTDR TESTING. All traces will be provided in hard copy and diskette form using GR 196 format. This testing will be conducted at both 1310 nm and 1550 nm wavelengths when the Leased Fiber consists of Standard Single Mode Fiber, but will be done at 1550 nm only if the Leased Fiber consists of either Dispersion Shifted Fiber (True-WaveTM, LEAFTM, etc.) or a combination of Single Mode and Dispersion Shifted fiber types. OTDR testing will be conducted on a bi-directional basis for each Leased Fiber in each span at the appropriate wavelengths for the Leased Fiber described above. However, if due to length or attenuation reasons that the Leased Fiber span exceeds the dynamic range of an OTDR, a portion or all of the span may be tested on a unidirectional basis only. Alternatively, the Leased 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 a Carrier intends to accept Leased Fiber that is not terminated at one end by MFN in a fiber distribution panel (such as in a manhole or handhole) only unidirectional testing will be performed.

OTDR TESTING. This testing will be conducted at both 1310 nm and 1550 nm wavelengths when the Leased Fiber consists of Standard Single Mode Fiber, but will be done at 1550 nm only if the Leased Fiber consists of either Dispersion Shifted Fiber (True-WaveTM, LEAFTM, etc.) or a combination of Single Mode and Dispersion Shifted fiber types. OTDR testing will be conducted on a bi-directional basis for each Leased Fiber in each span at the appropriate wavelengths for the Leased Fiber described above. However, if due to length or attenuation reasons that the Leased Fiber span exceeds the dynamic range of an OTDR, a portion or the entire span may be tested on a unidirectional basis only. Alternatively, the Leased 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 a Customer intends to accept Leased Fiber that is not terminated at one end by MFN in a fiber distribution panel (such as in a manhole or handhole) only unidirectional testing will be performed. The turnover documentation package delivered to Customer will contain the actual traces that detail the testing parameters (including pulse width, averaging and range). The average bi-directional splice loss for all splices within each span will be of 0.15 dB or less while each connector pair (such as at a FDP) will have an average bi-directional loss of 0.5 dB or less. (Note that the front and end connector of the span can only be measured uni-directionally and will also have a loss equal to or less than 0.5 dB). In the event that OTDR acceptance testing must be done on a unidirectional basis (for reasons described above), an average per span splice loss will be 0.30 dB. If the average bi-directional splice loss of each span exceeds 0.15 dB (or 0.30 dB uni-directionally), MFN will provide upon the Customer's request documentation of at a least three attempts to reduce this value to below 0.15 dB (0.30 dB uni-directionally). The only exception to this will be in the instance of a splice between two different fiber types (Standard Single-mode to Dispersion Shifted, Depressed-Clad to Matched Clad, fibers with different mode-field diameters). Customer should also note that the loss and/or reflectance of the front-end connector (as measured using a launch cord) is only an indicator of a problem such as a defective port, bulkhead, or the like. Since a different patch cord will be used by Customer (that connects to their equipm...

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

OTDR TESTING. 23.1 After all splice points for the fiber optic spans are completed, Contactor shall record measurements of the splice losses with an Optical Time Domain Reflectometer (OTDR). These measurements must be made after the splice cases are closed and permanently racked in manhole/handhole or lashed to strand in order to check for macro- bending problems, unless directed by Company where temporary testing splices are required. Contractor shall follow Company specifications to test the fiber optic cable as well as the specifications of the cable manufacturer and the equipment manufacturer. 23.2 Company has standardized on GN NetWorks Optical Test System Emulation Software for analyzing, reporting and printing OTDR traces. The GN Networks software is able to read GN Nettest T5 format OTDR traces or Bellcore – GR-196 CORE OTDR Data Standard (Issue 1, 9/95) format traces. Company requires the use of OTDRs that are able to produce one of these trace formats for the acceptance testing. OTDRs that are acceptable for testing on include; but not limited to; models CMA 4000/8800 and TD-3000. Operations of these OTDRs shall be in accordance with the manufacturer’s specifications. 23.3 Contractor shall note the fiber type and calibrate all testing and splicing equipment as applicable. This shall include, but not be limited to, dispersion, clad, pulse width, range, scan rate, and refractive index. Contractor shall set the machine to match the manufacturer’s recommendation for the fiber being tested. Contractor shall use the same calibration for all similar type fibers in both directions within the same fiber optic span under test. Fibers shall be tested with an OTDR at 1310 nm and 1550 nm for Standard Single Mode Fiber. 23.4 Contractor shall test all fibers bi-directionally, after splicing has occurred. If testing from a terminated end, Contractor shall utilize a minimum of a one-kilometer (1 km) launch cord / pulse suppressor. Contractor shall allow enough time during the production of a trace to allow the signal to normalize before recording. 23.5 Contractor shall analyze the results of the OTDR testing to correct deficiencies in the field splices. Company’s guidelines for individual and overall fiber optic span splice loss shall be as follows: Splice Method Glass Type Uni- Directional Guideline (+/-) Power Meter Span Splice Loss Factor (@ 1310nm) Power Meter Span Splice Loss Factor (@ 1550nm) Single Fusion Single Mode 0.20 dB 0.10 dB 0.10 dB Mass Fusion Single Mode 0.30 ...

OTDR TESTING. Optical Time-Domain Reflectometry (OTDR) traces will be taken and splice loss measurements recorded and summarized on data sheets. For any span, OTDR testing will be performed where the fiber is terminated with a connector. OTDR testing will be conducted at both 1310nm and 1550nm wavelengths. OTDR testing will be conducted on a bi-directional basis for each Fiber(s) in each Segment at the appropriate wavelengths described above. The Acceptance Package will contain the actual traces that detail the testing parameters.

OTDR TESTING. Each Strand will be tested bi-directionally using a recently calibrated OTDR. Zayo will use the appropriate settings as per the OTDR manufacturer’s recommendation depending on dark fiber type and segment distance. Bi-directional OTDR Traces will be recorded using the same setting on the OTDR.
