SaskTel servicing guidelines
for
existing Multi-Dwelling
Units
No additional fire-stopping is needed for electrical apparatus such as boxes, junction boxes, and
fixtures which have been tested and approved for use in fire‐rated assemblies other than normal
patching where the item penetrates‐a fire‐rated assembly.
If there are any further questions or concerns about fire-stopping consult SaskTel BICS.
Please refer to the special note at the beginning of Section 1 on page 4.
3.3. Spaces (see previous on spaces required for fiber entrance devices)
SaskTel requires spaces, suitable for the installation and maintenance of the Fibre Optic
Network equipment, that are safe, secure and easily accessible. For the installation of
connection equipment, (FDH, FDT, and FSB), the following points should be considered:
• ease of access by SaskTel,
• secure from damage or tampering,
• having adequate lighting,
• dry and free from moisture damage,
• clean and free of dust of vaporous chemicals, and
• will not cause an obstruction hazard.
3.4. Inside Fibre Cable
There are various types of bend insensitive interior cables available for use. The style of
pathway used typically determines the type of fibre. Though most can be used with different
pathway designs, each has its own particular intended uses.
Every inside cable contains 900um tight buffered bend insensitive fibre optic glass. The fibre
optic glass is rated to a G.657 b2 level which has a reduced acceptable bend radius of 7.5mm
with low or no power loss.
What differentiates types of fibre are the jackets used to protect the glass and its bend radius.
Indoor ruggedized 3.0mm fibre – This is typically 3.0mm fibre in a riser rated thin tuff jacket.
Its light weight and small diameter along with amarid yarn make it ideal for single cable to unit
conduit use.
Indoor/outdoor 5.0mm fibre – This bend insensitive fibre is typically a 5.0mm riser rated fibre
that is weather hardened for interior and exterior use. It’s flexible but very thick jacket make this
cable ideal for non-conduit installations where the cable is to be stapled to wood framing.
Indoor/outdoor Crush Resistant Fibre - This is a bend insensitive fibre that is jacketed in its
own riser rated corrugated 3.0mm conduit. Though it is more expensive, having its own conduit
is ideal for applications requiring durability & protection against cutting crushing and kinking.
Suggested use in non-conduit installations, especially where there is an increased possibility of
nicks or cuts, as in metal stud construction.
Indoor Riser Cable – this cable contains multiple strands of bend insensitive 250um or 900um
tight buffered fibre. Though the common versions come with a typical thin ft-4/6 rated jacket,
there is a version that can be ordered with an interlock armored jacket similar to the ruggedized
