Product details
Overview
AFBR-710FMZ from Broadcom (formerly Avago) is a 10G Fibre Channel SFP+ optical transceiver with 850 nm VCSEL transmitter and PIN photodiode receiver, compliant with ANSI 10G Fibre Channel and SFF-8431/8432 specifications, supporting 300 m over OM3 multimode fiber and operating at 0–70 °C case temperature in high-port-density storage area network (SAN) switches.
For engineers reviewing the AFBR-710FMZ datasheet, pinout, applications, or equivalent options, this page delivers verified electrical interface timing, digital diagnostic monitoring (SFF-8472), hot-plug ESD-safe mechanical compliance, Class 1 laser safety certification, and real-time Tx_Bias/Tx_Power/Rx_Power telemetry for predictive failure identification in mission-critical Fibre Channel infrastructure.
Technical Context
The AFBR-710FMZ implements a fully integrated SFP+ form factor with CML-based 10.51875 GBd transmit/receive data paths, dual 3.3 V supplies (VccT/VccR), and two-wire serial interface (SCL/SDA) addressing EEPROM pages at 0xA0 (SFF-8431) and 0xA2 (SFF-8472 diagnostics). Its VCSEL-based TOSA and PIN-based ROSA are optimized for 850 nm multimode operation with encircled flux compliance per TIA-492AAAC.
It supports full digital diagnostic management including real-time monitoring of temperature, supply voltage, Tx bias current, Tx optical power, and Rx optical power, with status flags (TX_FAULT, RX_LOS) mirrored in memory and accessible via I²C. Predictive failure identification relies on trend analysis of Tx_Bias and Tx_Power to anticipate laser degradation before link errors occur.
Key Specifications

Pinout & Package
SFP+ 20-pin edge connector in metal housing compliant with SFF-8432 Improved Pluggable Formfactor (IPF); LC duplex optical interface per ANSI TIA/EIA-604-10 (FOCIS 10A).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 10, 11, 14, 17, 20 | VeeT / VeeR | Isolated signal grounds for transmitter and receiver sections - prevents crosstalk and maintains CML signal integrity. |
| 2 | TX_FAULT | Open-collector LVTTL output indicating catastrophic laser fault - requires external pull-up; latched until TX_DISABLE toggle or power cycle. |
| 3 | TX_DISABLE | LVTTL input disabling optical output - internally pulled up; asserted via hardware or I²C (A2h byte 110 bit 6). |
| 4, 5 | SDA, SCL | I²C bidirectional lines for SFF-8431 (0xA0) and SFF-8472 (0xA2) memory access - enable host readout of diagnostics and configuration. |
| 6 | MOD_ABS | Module absent indicator - open-drain output tied to VeeT/VeeR; signals module insertion/removal to host controller. |
| 8 | RX_LOS | LVTTL output signaling loss of valid optical signal - indicates broken fiber, remote transmitter failure, or excessive attenuation. |
| 12, 13 | RD−, RD+ | CML differential receiver outputs - AC-coupled, require external 100 Ω termination; deliver recovered 10.51875 GBd data to SERDES. |
| 18, 19 | TD+, TD− | CML differential transmitter inputs - internally terminated and AC-coupled; accept 10.51875 GBd data from host SERDES with 180–700 mVpp swing. |
| 15, 16 | VccR, VccT | +3.3 V supplies for receiver and transmitter - must not differ by >0.5 V; noise tolerance ≤66 mVp-p (10 Hz–10 MHz). |
Key Features
| Feature | Design Value |

FAQ
What is the primary compliance standard for AFBR-710FMZ?
The AFBR-710FMZ is explicitly compliant with the ANSI 10G Fibre Channel specification (FC-PI-4) and the SFF Committee's SFF-8431/8432/8472 standards. It is not certified to IEEE 802.3ae 10GBASE-SR, though it shares physical layer similarities. Its optical and electrical parameters - including OMA, extinction ratio, and stressed sensitivity - are validated against Fibre Channel requirements, not Ethernet.
Does AFBR-710FMZ support digital diagnostics, and how are they accessed?
Yes, AFBR-710FMZ fully supports SFF-8472 digital diagnostics via its two-wire I²C interface (SDA/SCL pins). Real-time values for temperature, Vcc, Tx_Bias, Tx_Power, and Rx_Power are stored in EEPROM page 0xA2, bytes 0–255. Host systems read these using standard I²C transactions, enabling predictive failure identification and compliance monitoring without additional hardware.
What is the maximum supported link distance and fiber type for AFBR-710FMZ?
The AFBR-710FMZ supports up to 300 meters over 50 µm OM3 multimode fiber and 400 meters over OM4 multimode fiber at 10.51875 GBd. It is not designed for single-mode fiber use. Its optical launch condition meets TIA-492AAAC encircled flux requirements, ensuring compatibility with industry-standard OM3/OM4 cabling plants.
Is AFBR-710FMZ hot-pluggable, and what ESD protection does it provide?
Yes, AFBR-710FMZ is fully hot-pluggable per SFF-8432 and supports insertion/removal while the host system is powered. Its mechanical design ensures initial contact with the SFP+ cage before electrical connection, mitigating ESD risk. It meets MIL-STD-883C Class 1 (>2 kV) for pin ESD and withstands 15 kV air discharge to the optical connector per IEC 61000-4-2.
What laser safety classification applies to AFBR-710FMZ, and how is it enforced?
AFBR-710FMZ is certified Class 1 Laser Product per IEC 60825-1 and US FDA 21 CFR Part 1040.10, with CDRH certification No. 9720151-128. Safety is enforced by an integrated eye-safety circuit that continuously monitors optical output power and disables the VCSEL within microseconds if the Class 1 limit is exceeded - whether due to host supply fluctuation or internal fault.
