AFBR-709DMZ-IN3 Intel Compatible 10GBASE-SR SFP+ Transceiver

Avago (now Broadcom) produced the AFBR-709DMZ as a 10GBASE-SR SFP+ with enhanced digital diagnostic monitoring capabilities. The -IN3 suffix on AFBR-709DMZ-IN3 designates the Intel OEM variant, carrying Intel-specific EEPROM vendor codes and product identifiers. Intel's Ethernet server adapter product lines reference this part number in their qualified transceiver lists, including the X520-DA2, X710-DA2, and E810-XXVDA2 (25G adapter, backward compatible at 10G) families. The module is designed for duplex multimode fiber links using LC/UPC connectors and is hot-pluggable in standard SFP+ cages.

The transceiver transmits at 850 nm using a VCSEL laser and receives with a PIN photodiode. Minimum optical budget is 6.1 dB, supporting 300 m reach on OM3 and 400 m on OM4 multimode fiber. Actual achievable distance depends on the installed fiber conditions, including connector and splice losses along the link. Data rate range covers 1.25 to 10.3125 Gbps for 10 Gigabit Ethernet (IEEE 802.3ae) and Gigabit Ethernet applications. Where the host adapter and network switch both support it, the host port can be configured for 1GbE where the adapter supports dual-rate operation. The module operates in the commercial temperature range of 0 to 70 C. SFP+ form factor conforms to SFF-8431 (electrical) and SFF-8432 (mechanical).

DDM/DOM monitoring per SFF-8472 provides real-time readings for optical transmit power, receive power, laser bias current, module temperature, and supply voltage. Alarm and warning thresholds are factory-programmed to IEEE 802.3ae limits, enabling proactive link monitoring through Intel adapter management utilities and standard Linux ethtool queries. The enhanced diagnostics in the 709DMZ design provide DDM/DOM diagnostics per SFF-8472 covering Tx/Rx power, bias current, temperature, and voltage. All diagnostic registers respond correctly to host polling at both A0h (base ID) and A2h (monitoring) I2C addresses as defined in SFF-8472. The module supports real-time threshold crossing alerts when configured through the Intel NIC driver or OS-level monitoring tools.

EdgeOptic builds this compatible on the 10G-SFP-300 platform with Intel-recognized EEPROM programming. The module passes Intel NIC firmware validation and reports correct vendor data in ethtool, Intel PROSet, and adapter management utilities. Don't confuse the AFBR-709DMZ-IN3 with the AFBR-703SDZ-IN2: the 709DMZ is a 10G SFP+ (10.3125 Gbps), while the 703SDZ base module targets a different speed class. CE and RoHS certified.
