Loss of Signal
The Loss of Signal (LOS) output indicates that the optical
input signal to the receiver does not meet the minimum
detectablelevel for FDDI and OC-3 compliant signals.
When LOS is high it indicates loss of signal. When LOS is
low it indicates normal operation. The LOS thresholds are
set to indicate a definite optical fault has occurred (e.g.,
disconnected or broken fiber connection to receiver, failed
transmitter).
Module Package
The transceiver meets the Small Form Pluggable (SFP)
industry standard package utilizing an integral LC duplex
optical interface connector. The hot-pluggable capability
of the SFP package allows the module to be installed at
any time – even with the host system operating and on-
line. This allows for system configuration changes or
maintenance without system down time. The HFBR-57E0
uses a reliable 1300 nm LED source and requires a 3.3 V
dc power supply for optimal design.
Module Diagrams
Figure 1 illustrates the major functional components of
the HFBR-57E0. The connection diagram of the module is
shown in Figure 2. Figures 5 and 7 depict the external
configuration and dimensions of the module.
Installation
The HFBR-57E0 can be installed in or removed from any
MultiSource Agreement (MSA) – compliant Small Form
Pluggable port regardless of whether the host equipment

is operating or not. The module is simply inserted,
electrical interface first, under finger pressure. Controlled
hot-plugging is ensured by design and by 3-stage pin
sequencing at the electrical interface. The module housing
makes initial contact with the host board EMI shield
mitigating potential damage due to Electro-Static
Discharge (ESD). The 3-stage pin contact sequencing
involves (1) Ground, (2) Power, and then (3) Signal pins,
making contact with the host board surface mount
connector in that order. This printed circuit board card-
edge connector is depicted in Figure 2.
