Multimode Small Form Factor Pluggable Transceivers with LC Connector and Conformal Coating, DMI for FDDI and Fast Ethernet

Currently Viewing:

The Broadcom AFBR-57E6APZC is a low power, 125MBd 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-57E6APZC is specially designed for harsh environments. PCB and all electronic parts (except for the plug-in contacts) are protected by a conformal coating which secures high lifetime and low FIT under conditions like corrosive atmosphere and salt dust atmosphere.  It fulfills the related standards EIA-364-65B Class IIIA and ASTM B 117.     
The AFBR-57E6APZC 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-57E6APZC 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).
