Broadcom's AFBR-57E6APZ-HT is a low power, 125 MBd small form-factor pluggable (SFP) fiber optic transceiver module device designed for Fast Ethernet and fiber distributed data interface (FDDI) applications. The device has an LC duplex connector optical interface and a digital diagnostic monitoring interface (DMI).

The AFBR-57E6APZ-HT is compatible to the SFF-8074i for conventional SFP interface and the SFF-8472 for DMI. By way of 2-wire serial communications as defined in the SFF-8472 MSA, the AFBR-57E6APZ-HT can provide real time information on temperature, LED bias current, LED average output power and receiver average input power. The device also has the ability to monitor the receiver loss of signal (RX_LOS).

The AFBR-59E4APZ-HT is a low power, small form factor (SFF) Fast Ethernet optical transceiver in the industry standard 2 DIP x 5 DIP style with LC fiber connector interface. The transceiver is compatible with the optical performance requirements of 100Base-FX version of IEEE 802.3u. It uses a 1310 nm LED and provides multimode operation both on 50 µ and 62.5 µ fibers with link distances up to 2 km. Data interface for input and output is differential LVPECL, and a signal detect output is provided on single-ended LVPECL. The maximum operating temperature is +95°C, which is especially beneficial in industrial system environments.
