CHAPTER 2: Introduction
Each SFOM-HS2 converts the electrical data signal
from the DTE interface into light pulses for trans-
mission across the fiber interface. It can operate
at 56 or 64 Kbps, and can transmit data as far as
2.5 miles (4 km); see
Figure 2-1
below.

Each unit also supports two ITU V.54 industry-
standard loop tests for easy, convenient diagnostics
(see
Section 4.3
).
The SFOM-HS2 can get its transmit timing from
any of three sources: its own oscillator (internal
clock), the attached DTE (external clock), or
the receive signal (recovered clock).
