Broadcom AFBR-57B4APZC LC Duplex SFP Transceiver
Broadcom AFBR-57B4APZC LC Duplex SFP Transceiver enables system designers to implement DC to 50MBaud data transmission over 2km with (62.5µm/125µm) multimode fibers. The AFBR-57B4APZC LC Duplex SFP Transceiver supports an LC duplex connector. The Broadcom AFBR-57B4APZC Transceiver uses the 2-wire serial interface defined in the SFF-8472 MSA, providing real-time information on module temperature, transmitter supply voltage, and receiver average input power. The transceiver exhibits increased robustness in harsh environments due to conformal coating.
The AFBR-57B4APZC transmitter comprises 850nm Class 1 laser-compliant VCSEL with an integrated driver IC. The AFBR-57B4APZC receiver uses a fully integrated single-chip solution that provides excellent immunity to EMI and fast transient dV/dt rejection. The transceiver package is compatible with the Small Form Pluggable (SFP) MSA with the LC duplex connector option. The SFP package offers hot-pluggable capability, allowing the module to be installed even when the host is online and operating. The transceiver requires a 3.3VDC power supply for optimal performance.
