SFOM-HS2
2. Introduction
The SFOM-HS2 is a high-speed fiberoptic local
(short-haul) modem. You can use pairs of SFOM-
HS2s to make extended-distance, full-duplex
connections across fiberoptic cable between
synchronous or asynchronous terminals, PCs, or
controllers on one end and high-speed computers
on the other.
There are four models of SFOM-HS2 available (see
Table 2-1
below). Each has fiberoptic connectors on
one side for attaching fiberoptic cable, and a DB25
connector on the other side for attaching your
data-terminal equipment (DTE). (The V.35 models
include a special adapter cable that patches the
DB25 connector to a 34-pin M-block connector
more appropriate for most V.35 equipment.)
