Product details
Overview
AFBR-7CER03Z from Broadcom (formerly Avago Technologies) is a 3-meter SFP+ Active Optical Cable (AOC) designed for 10GbE interconnects in high-port-density systems. It delivers 10.3125 Gbps data rate per lane, 1E-15 BER performance, and operates across 0–70°C with 850 nm VCSEL/PIN optics and 275 mW nominal power per end.
For engineers reviewing the AFBR-7CER03Z datasheet, pinout, applications, or equivalent options, key selection criteria include SFP+ mechanical compliance (SFF-8432 IPF), two-wire serial management interface (Page A0h), Rx_LOS/Tx_DISABLE support, Class 1 laser safety, and compatibility with 10GbE, 8GFC, FCoE, and InfiniBand QDR/DDR protocols.
Technical Context
The AFBR-7CER03Z implements a fully integrated, non-retimed optical link using Avago's proven 850 nm VCSEL transmitter and PIN photodiode receiver. It complies with SFF-8431 electrical and SFF-8432 mechanical specifications, supporting direct connection to SFP+ host ports without external CDR or retiming circuitry.
No embedded retimer or CDR enables low-latency, transparent signal transmission at data rates from 1 to 10.3125 Gbps. Its 20-pin SFP+ edge connector interfaces via I²C-compatible two-wire serial bus (SFF-8472 Page A0h) for digital diagnostics monitoring (DDM) and control functions including Tx_DISABLE and Rx_LOS assertion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed optical interconnect applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-7CER05Z | 5-meter cable length; identical optics, power, and interface specs | Supports longer reach between adjacent racks; same thermal and EMI profile | Select when interconnect distance exceeds 3 m but remains ≤5 m and SFP+ port density is unchanged |
| AFBR-703SDZ | Pluggable SFP+ transceiver (not AOC); requires separate MMF patch cables; 300 m OM3 reach | Enables flexible, reconfigurable fiber routing; higher system-level latency due to duplex fiber path | Select when topology requires field-replaceable optics or distances >3 m up to 300 m |
Compared with AFBR-7CER03Z, AFBR-7CER05Z offers extended reach with identical electrical/optical behavior, while AFBR-703SDZ trades fixed-length simplicity for field flexibility and longer reach at the cost of added fiber management and latency.

FAQ
What is the maximum supported data rate for AFBR-7CER03Z?
The AFBR-7CER03Z supports a maximum data rate of 10.3125 Gbps per lane, fully compliant with 10GBASE-SR and SFF-8431 specifications. It operates without embedded retimers or CDRs, enabling transparent transmission from 1 Gbps up to 10.3125 Gbps. This makes AFBR-7CER03Z suitable for multi-protocol use in 10GbE, 8GFC, and InfiniBand QDR applications without firmware updates or configuration changes.
Does AFBR-7CER03Z require external power or host-side configuration?
No, AFBR-7CER03Z draws all operating power from the host SFP+ port's 3.3 V supply and requires no external power source or host-side firmware configuration. It implements SFF-8472-compliant two-wire serial interface (Page A0h) for basic DDM readout and Tx_DISABLE control, but operates plug-and-play with default settings. AFBR-7CER03Z is fully interoperable with any SFF-8431-compliant host without driver or BIOS modifications.
Is AFBR-7CER03Z compatible with standard SFP+ cages and PCB footprints?
Yes, AFBR-7CER03Z conforms to the SFF-8432 Improved Pluggable Formfactor (IPF) mechanical specification and fits all INF-8074 and SFF-8431/2-compliant SFP+ cages and PCB footprints. Its dimensions (98.5 × 13.8 × 11.95 mm) and 20-pin edge connector match industry-standard SFP+ modules, enabling drop-in replacement of passive copper DACs without board layout changes.
What safety certifications does AFBR-7CER03Z hold?
AFBR-7CER03Z is certified Class 1 Laser Product per EN 60825-1:2007 and EN 60825-2:A2:2010, ensuring no hazardous optical radiation is accessible during normal operation or single-fault conditions. It also complies with RoHS directives in both EU and China jurisdictions, confirming absence of lead, mercury, cadmium, and other restricted substances in its construction and assembly.
How does AFBR-7CER03Z compare to passive copper DACs in thermal performance?
AFBR-7CER03Z dissipates only 275 mW per end versus typical 600–900 mW for 3-meter passive copper DACs, significantly reducing localized heat buildup in high-port-density systems. Its optical architecture eliminates resistive losses and skin-effect degradation, allowing consistent signal integrity across temperature and enabling tighter thermal margins in 1U switches. This makes AFBR-7CER03Z more thermally efficient than copper alternatives at the same reach.
