Intel AFBR-703SDZ-IN2 Compatible Dual-Rate 1G / 10G SFP+ SR Transceiver

EdgeOptic's AFBR-703SDZ-IN2 compatible is an Intel-coded dual-rate version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR / SW SFP+ transceiver. The OEM module is an Avago AFBR-703SDZ optical engine carrying Intel OEM EEPROM coding, identified by the -IN2 suffix that Intel uses on SFP+ optics qualified for its X520 and X710 server-adapter families. Intel cross-references this OEM SKU in its X520 / X710 server-adapter accessory matrix; verify the exact Intel internal part code at quote stage. Avago acquired the legacy Broadcom Corporation in 2016, and the combined company today markets and supports the AFBR-703 product line under the Broadcom brand; the original Avago datasheet branding is retained on the part.

The AFBR-703SDZ is a dual-rate variant supporting both 10GBASE-SR (10.31 Gbps) and 1000BASE-SX (1.25 Gbps) over the same 850 nm multimode optic. This matters for Intel adapters that auto-negotiate or are configured to step down from 10G to 1G during link bring-up. The newer Intel OEM revision in this product line is AFBR-703MDZ-IN2, which uses the same Intel OEM EEPROM scheme on an updated hardware revision.

Optical specs follow the 10G-SFP-300 root: 850 nm transmit and receive, 20 nm bandwidth (840 to 860 nm), 300 m over OM3 and 400 m over OM4 / OM5 multimode fiber, duplex LC/UPC connector, 6.1 dB average link budget. Transmit power is −5 to 0 dBm, receiver sensitivity is −11.1 dBm, and receiver overload is 0 dBm. The transmitter is a VCSEL laser, the receiver a PIN photodiode, and DOM/DDM is supported per SFF-8472.

The -IN2 suffix is an Intel OEM EEPROM coding designator and is not an industrial-temperature designator. Operating temperature is the standard commercial 0 to 70 °C range, matching the 10G-SFP-300 root specification. Standard target hosts are Intel X520 and X710 server adapter families. The EdgeOptic compatible carries Intel-recognized vendor identification used for the -IN2 suffix so the optic appears as a recognized SFP+ on these adapters; verify the host driver and OS revision against Intel's adapter compatibility table before deployment, since some driver versions enforce stricter SFP+ vendor checking than others. Sibling EEPROM codings on the same physical AFBR-703SDZ optic (such as -BN1, -ELX, -HP8, -IB2) are sold for different host vendors and are not interchangeable with the -IN2 part on Intel adapters.
