SPECIFICATIONS (REVISED)
FOR
INSTALLATION OF FIBER-OPTIC CABLE
AT
SANTA CLARA COUNTY OFFICE OF EDUCATION
SCOPE OF WORK
The Santa Clara County Office of Education (SCCOE) requires the installation of 12-strand multi-mode
fiber connections between the new Data Center Main Distribution Frame (MDF) and six (6) Intermediate
Distribution Frame (IDF) closets.

OPTION A: 12-strand plenum fiber-optic cable per specifications in Section 2.1.2.
Option A-1: 12-strand plenum fiber-optic cable installation and termination.
Option A-2: Pull an additional 12-strand plenum fiber-optic cable. Installed but not
terminated to be held for future use.
OPTION B: Armored 12-strand plenum fiber-optic cable per specifications in Section 2.1.3.
Option B-1: Armored 12-strand plenum fiber-optic cable installation and termination.
Option B-2: Pull an additional armored 12-strand plenum fiber-optic cable. Installed but not
terminated to be held for future use.

tensile load of 400 lb. without stretching
2.1.4 Approved Manufacturers/Suppliers
1) Ortronics
2) Corning
3) Berk-Tek
4) Products of equal quality from other manufactures will be considered.
5) All cable installed must be approved by project manager prior to installation.
3.0 FIBER INSTALLATION
3.1 Inter-Building Cable
Fiber cable is to be supported by 4-inch “J” hooks every six (6) feet throughout the run.
3.2 Miscellaneous
At each end of the fiber run a twenty (20) foot service loop shall be left to facilitate future relocation.
Slack shall be mounted on walls or on ladder racks at the contractor’s discretion with the project
manager’s approval.
4.0 FIBER TERMINATION
The terminal ends of all new fibers cable strands shall be terminated on the fiber trunk cable.
Fiber termination and components must meet or exceed the following specifications:
4.1 Fiber Termination Shelves
Each of the six (6) IDF closet installations shall include a new 1U rack-mountable fiber termination shelf
that shall accommodate 12-strand fiber terminations. The MDF installation shall include an appropriate
number of shelves to accommodate all new IDF terminations.
4.1.1 Fiber Shelf Specification
Fiber termination shelves shall meet the following specifications:
a. rack mountable 1U or 4U
b. fully modular in design
c. provide security and protection
d. be accessible from both front and rear
e. capable of terminating buffered fiber-optic cable
f. provide adequate strain relief for cables
4.1.2 Approved Manufacturers/Suppliers
1) Ortronics
a. OR-FC01U-M
b. OR-FC04U-M

5.0 TESTING
5.1 Before Installation
It is suggested that each individual fiber in a cable be tested for length and transmission anomalies while
on the reel before installation.
5.2 After Installation and termination
5.2.1. All multimode fiber strands shall be tested end-to-end for bi-directional attenuation at
850 nm/1300 nm. Tests should be conducted in compliance with EIA/TIA-526-14 or according to
the manufacturer’s instructions for the test set being utilized.
5.2.2. After the cable is in place it shall be tested in the following manner:
a. After termination, each fiber shall be tested for length, transmission anomalies, and
end-to-end attenuation. Results are to be supplied to ISC.
b. After termination and mounting, each terminated fiber is to be tested for end-to-end
loss. Results are to be supplied to ISC.
c. The maximum allowable attenuation for any termination is 0.3 dB.
5.2.3. The contractor shall review all terminated connectors with a fiber inspection
scope following the final polish. Connector ends with any anomalies, scratches or pitting shall
be re-polished or replaced to remove the defects.
Any deviation from these test procedures must be approved in writing in advance by ISC.
