The BFOC connectors allow precision fiber-optic cable connections. The
construction of the BFOC connector allows the strain relief of cables to be used.
This is necessary for installing longer fiber-optic cable connections, for example
between OLM/P modules. BFOC connectors must be ordered separately.

Ordering information and instructions on fitting the connectors can be found in
Appendix D.
