Loss of Signal
The Loss of Signal (LOS) output indicates that the optical
input signal to the receiver does not meet the minimum
detectable level for FDDI compliance. When LOS is high,
it indicates a link failure such as a disconnected or broken
fiber connection or a malfunctioning transmitter.
Module package
The transceiver package is compliant with the Small
Form Pluggable (SFP) MSA with the LC duplex connector
option. 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 permits the
system to be configured or maintained without system
downtime. The HFBR-57E5APZ requires a 3.3 V DC power
supply for optimal performance.
Module Diagrams
Figure 1 illustrates the major functional components
of the
module is shown in Figure 2. Figures 5 and 7 depict the
external configuration and dimensions of the module.
Installation
The HFBR-57E5APZ 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, electri-
cal 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

edge connector is depicted in Figure 2.
Digital Diagnostic Interface and Serial Identification
The 2-wire serial interface is based on the ATMEL AT24C01A
series EEPROM protocol. Conventional EEPROM memory
(bytes 0-255 at memory address 0xA0) is organized in
compliance with SFF-8074i. As an enhancement the
HFBR-57E5APZ is also compatible to SFF-8472. This
enhancement offers digital diagnostic information at
bytes 0-255 at memory address 0xA2.
In addition to monitoring of the LED drive current and
photodiode current, the interface also monitors the trans-
mitter supply voltage and temperature. The transmitter
voltage supply must be provided for the digital diagnostic
interface to operate.
