S.I. Tech model 2109 is a mini optical Multidrop Bit-Driver. The upstream and downstream fiber ports repeat data through the 2109 multidrop and drop/insert data on the RS-232 port. The RS-232 port inserts data onto the upstream fiber port only, and gets data dropped from the upstream fiber port only. The downstream fiber port only sends/receives data from the upstream fiber port.
