Fiber Testing Specifications Summary

This attachment to the Illinois Department of Innovation and Technology contract B-50657 REBID for Fiber Construction Services in the North Region establishes the fiber testing requirements and acceptance criteria for dark fiber installation. The specifications require that contractors conduct non-destructive attenuation testing and Optical Time Domain Reflectometer (OTDR) testing to verify that installed fiber optic cables meet defined performance standards. Testing must include continuity uniformity tests at 1310 nm and 1550 nm wavelengths, optical length measurements, splice loss measurements conducted bi-directionally, and end-to-end loss verification using industry-accepted laser sources and power meters.

The fiber acceptance standards mandate maximum bi-directional average splice loss of 0.15 dB, attenuation limits of 0.35 dB/km at 1310 nm and 0.25 dB/km at 1550 nm, connector loss not exceeding 0.5 dB per connector, and fiber that meets or exceeds Corning Single Mode Fiber SMF-28 specifications. Contractors must document all test results and deliver technical specifications, electronic route maps in ESRI shape file format, acceptance test results in PDF, XLS, and CSV formats, and 24-hour contact information for network operations before the State will consider job acceptance. The specification allows acceptance of out-of-specification test results if the condition does not affect transmission capability or create a significant possibility of outage based on prevailing telecommunications industry standards.

Attachment C – Fiber Testing

Fiber Testing

1. Fiber Specifications

a. The maximum bi-directional average splice loss shall not exceed 0.15 dB.

b. All splices shall be sealed in water proof splice enclosures.

c. Attenuation at 1310 nm = 0.35 dB/km max

d. Attenuation at 1550 nm = 0.25 dB/km max

e. Connector loss shall not exceed 0.5 dB per connector

f. Fiber will meet or exceed Corning Single Mode Fiber SMF-28 Specifications

g. Event Reflectivity (Minimum ORL) should not exceed 27 dB.

2. Fiber Acceptance Testing

Contractor will conduct the following tests as part of its Acceptance Test Plan:

• Non-destructive Attenuation Tests (End to End)

• Optical Time Domain Reflectometer Tests (OTDR)

Fiber acceptance testing will be performed to ensure that the fibers will operate within the parameters of the Specifications set forth below.

a. More specifically, fiber acceptance testing will include the following:

• Continuity Uniformity Tests:

All fibers shall be tested bi-directionally at 1310 nm or 1550 nm, as applicable, with an

OTDR; the subsequent traces shall be inspected for end-to end continuity and for uniform attenuation. These traces will be attached to an email or contained on a removable storage drive.

• Optical Length:

The OTDR will be used to determine the end-to end optical length of the cable.

• Splice Loss:

Splice loss will be measured bi-directionally with an OTDR using the Splice Loss average method.

• End-to-End Loss:

Using a light source and a power meter, the bi-directional, connector-to-connector attenuation will be measured for each fiber at 1310 nm and 1550 nm, as applicable. The acceptance average attenuation per kilometer on a per span basis shall be the attenuation set forth by this agreement.

a. The end-to-end value as measured with an industry-accepted laser source and power meter should have an attenuation rating of less than or equal to the following:

(1) At 1310 nm: (0.35 dB/km x km of cable) +

(number of connectors x 0.50) +

(number of splices x 0.10)

(2) At 1550 nm: (0.25 dB/km of cable) +

(number of connectors x 0.50) +

(number of splices x 0.10)

b. Contractor loss / attenuation objective for each fiber optic splice is 0.10 dB (with a 0.15 upper limit) when measured in one direction with an OTDR test set (excluding connector loss, which is typically 0.50 dB per connector).

3. Out-of-Spec Testing

Test results outside the specifications listed above shall be noted, but shall not preclude acceptance of a fiber if the out-of-spec condition does not affect transmission capability (based on use of then-prevailing telecommunications industry standards applicable to equipment generally used with the relevant type of fiber) or create a significant possibility of an outage.

4. Documentation

Contractor shall deliver to the Customer the following documentation (the “Deliverables”) regarding the as-built condition of the Dark Fiber:

a. Technical specifications of the optical fiber cable and other equipment used in installing and providing the Dark Fiber.

b. Route details in electronic map format in ESRI shape files. At a minimum, the maps will show demarcation points, route, existing splice locations and indication of whether fiber is aerial or buried. Contractor shall provide updated maps to Customer upon request, not to exceed two times in any 12-month period.

c. ‘Fiber Acceptance’ test results in the following formats: PDF, XLS and CSV (Nothing all testing at 1310 and 1550).

d. 24-hour telephone numbers for Contractor Network Operation Control Center.

Deliverables shall be supplied before the State will consider job acceptance.
