SaskTel servicing guidelines

for

existing Multi-Dwelling

Units

4.2 Labelling

The contractor shall label all communication cables at both ends in a clear and legible manner.

For example, the cabling between the suite and the telephone room shall be labelled at both

ends with the function and Unit Number.

At the communication/telephone room end, a typical label would read, “TELCO1 - UNIT 102”. At

the suite end, the label would read “TELCO1 – IN”. The label shall be located within 12” of the

likely termination point after trim so the label will not be cut off.

Both sides of a dual cable shall be labelled.

4.3 Testing

4.3.1 Optical fibre cable

Even though bend insensitive fibre and the specified jackets aid in protecting them, fibre optic

cable is still glass and can be damaged. Therefore, all fibre drops installed must be tested

during the installation phase to allow replacement if necessary.

Continuity testing with a ruby red visual fault locator (VFL) is only acceptable for pre-wiring and

map/labelling.

All final testing shall be done with light sources and loss meters at 1550 nm.

Using a fibre’s final permanent termination connector for testing purposes would only be

necessary if that termination is completed in the permanent housing for the finished fibre unit

(e.g. a media panel fibre jack or IFDT/FSB/FDH). This is because fibre terminations cannot be

taken apart and are expensive to use as an interim test point.

In lieu of a permanent termination, temporary solutions can be implemented depending on the

tools on hand.

The acceptable interim fibre connector methods are:

• Temporarily fusion splicing a pigtail SC/APC connector, or a longer one side pre-

terminated patch cable onto the end of the fibre runs, then cutting and reusing it for

another test.

• Using the same pigtail or fibre patch cable, terminate using a 3M Fibrlok 2 , which can

be taken apart and reused multiple times. (See 3M guidelines for number of reuses).

• If using a permanent connector (outside of the finished housing): collect, cut, fan and

terminate the ends to equal and adequate lengths to be fed and finished into the

permanent housing at a later date. It is a sound practice to protect these ends by gently

coiling and bagging the loose fibre and connector ends into a temporary collector box or

bag; then securing the bog to the location where the fibre housing will be placed.
