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 capabil- ity 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 equip- Figure 2.

Controlled hot-plugging is ensured by design and by 3-stage pin se- quencing at the electrical interface. The module housing makes initial contact with the host board EMI shield miti- gating 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 con- tact with the host board surface mount connector in that order. This printed circuit board card-edge connector is depicted in Figure 2. Figure 1. Transceiver functional diagram |
