Notifier DS-RFM Converts multi-mode fiber ST style

Notifier DS-RFM fiber option module converts one of the two digital audio ports on a DAA2, DAX, DS-DB or DVC that mounts fiber option modules (DVC-EMPCC version or later) from wire to fiber. One or two fiber option modules may be installed, converting the DAA2, DAX, DS-DB or DVC partially or wholly to fiber optic communication. A DAL (digital audio loop) can support wire, single-mode fiber, and multi-mode fiber on the same loop with the use of fiber option modules.
