SOX - RS-485 Fiber Optic Transceiver (for single-mode fiber cable)

BAPI recommends fiber optic cable for HVAC communications networks that travel between buildings.

The SOX – Fiber Optic Transceiver converts the RS-485 data from the copper network to a fiber optic signal for transmission to other buildings. A SOX in the other building converts the fiber optic signal back into RS-485 for the remote copper network.

The SOX module accepts single-mode fiber cable on standard ST connectors. The copper RS-485 connection is made on the 8-pole plug along with the power and ground connections. The SOX also plugs into the communications repeater backplane (RBP).
