The Model 279 can also be used when the optical fiber type of the equipment is not compatible with the installed fiber optic cable.
The Model 279 is powered by a wall-mounted DC adapter that develops 12 V. By use of an internal DC-to-DC converter the user can supply any DC voltage from +8 V to +36 V for those situations where AC is not available.
The fiber optic ports of the Model 279 are provided on ST connectors.
