Fiber Optic Trunk Interface
Product Description
The Fiber Optic Trunk Interface (refer to Figure 1)
converts the building level network (BLN) and floor
level network (FLN) trunk electrical signals (RS-485)
into light energy for transmission over a fiber optic
cable and converts the light energy from a fiber
cable back to RS-485 signals. The device is
designed to work with either the BLN or FLN trunk at
speeds of 300 bps to 230K bps, with a link budget of
11.5 dB.
There are no internal settings or user-serviceable
parts in the Fiber Optic Trunk Interface. The
interface requires a duplex fiber cable between
interfaces (one fiber for transmit and one for
receive). ST style port connectors are included.
The Fiber Optic Trunk Interface is housed in a 1.5" ×
4" × 4" metal enclosure. It contains one power input
receptacle, one three-position trunk port, one fiber
transmit port, and one fiber receive port (refer to
Figure 2). The interface is powered by a 6 Vdc
external power pack (included). All circuits are
supervised and power limited.
