Intel compatible TXN31115D100000 Description
EdgeOptic's TXN31115D100000 compatible is an Intel-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver, positioned as the modern SR SFP+ replacement for hosts that have upgraded from 4Gb FC and 1GbE SFP cages to SFP+ ports. The original Intel TXN31115D100000 is a regular SFP (not SFP+) dual-protocol module supporting 1/2/4G Fibre Channel short-wave per FC-PI-2 (INCITS 404-2006) and 1000BASE-SX Gigabit Ethernet per IEEE 802.3z on the same hardware. The TXN31115D100000 was used in 4Gb FC SAN HBAs and 1G Ethernet SFP-caged hosts of the mid-2000s era, where rate-flexible SFP cages handled both Fibre Channel and Gigabit Ethernet traffic on shared optics.
The EdgeOptic 10GBASE-SR replacement is an SFP+ form factor module built to IEEE 802.3ae Clause 52, with a 6.1 dB optical budget, 850 nm VCSEL transmitter, LC duplex interface, transmit power between −5 and 0 dBm, and receive sensitivity better than −11.1 dBm. The reach envelope is 300 m on OM3 and 400 m on OM4 multimode fiber. The SR module is the forward-compatible replacement for HBAs and switch ports that have migrated from SFP cages to SFP+ cages. Hosts still running SFP-only cages on legacy 4Gb FC HBAs or 1Gb Ethernet SFP-caged adapters cannot accept SFP+ optics directly. Verify cage compatibility against the host HBA, NIC, or switch documentation before substituting.
Intel-recognized EEPROM coding identifies the module under the ordering code that hosts accepting Intel-coded SFP optics expect. Verify cage class and EEPROM acceptance against the host HBA, NIC, or switch documentation for the target platform before substituting. Digital diagnostics per SFF-8472 reports temperature, supply voltage, transmit bias current, transmit power, and receive power on every read. The EdgeOptic SR replacement runs to the Ethernet 10GBASE-SR specification at 10.3125 Gbps. The original TXN31115D100000 is a dual-protocol Fibre Channel and Gigabit Ethernet optic with its own 4.25 Gbps maximum signaling rate and FC-specific reach budget; the SR replacement is a 10G Ethernet optic; on hosts that support 1G SFP rate negotiation on the SFP+ port, the 10G-SFP-300 multi-rate envelope covers 1/2/4G FC and 1000BASE-SX backward rates per the root's Gigabit Ethernet and Fibre Channel application support. The replacement is not a like-for-like protocol substitute on a 4Gb FC SAN fabric that requires the original SFP form factor.

Frequently Asked Questions
Does replacing the TXN31115D100000 require a host with SFP+ ports?
Yes. The original Intel TXN31115D100000 is a regular SFP form factor module, while the EdgeOptic 10GBASE-SR replacement is SFP+. The two cages are mechanically distinct: an SFP+ optic does not fit in an SFP-only port. Hosts that have upgraded to SFP+ ports on current 10G server NICs, 8Gb or later FC HBAs, and modern SAN switches can accept the EdgeOptic 10GBASE-SR SFP+ directly. Legacy 4Gb FC HBAs and 1Gb Ethernet SFP-caged hosts that were never refreshed to SFP+ cannot accept SFP+ optics directly. Verify cage compatibility against the host HBA or switch documentation before substituting.
Is TXN31115D100000 a Fibre Channel module, an Ethernet module, or both?
Both. The original Intel TXN31115D100000 is a dual-protocol quad-rate SFP supporting 1G, 2G, and 4G Fibre Channel short-wave per FC-PI-2 (INCITS 404-2006) and 1000BASE-SX Gigabit Ethernet per IEEE 802.3z on the same hardware, with rate negotiated by the host. This dual-protocol capability distinguishes the TXN31115D100000 from FC-only 4Gb SFPs in the same era. The EdgeOptic 10GBASE-SR SFP+ replacement covers the 1G, 2G, and 4G Fibre Channel rates plus 1000BASE-SX Gigabit Ethernet under the 10G-SFP-300 root multi-rate envelope on hosts that support sub-10G SFP rate negotiation on the SFP+ port, with 8GFC and 10GBASE-SR extending the data-rate ceiling beyond the original TXN31115D100000 capability. Intel discontinued its 4Gb FC SFP product line during the mid-2000s era; for continued 8Gb FC SFP+ coverage on b-type Brocade-OEM SAN switches, the IBM 2054-5830 8Gb FC SFP+ ordering code applies on IBM SAN b-type platforms. Verify other vendor 8Gb FC SFP+ ordering codes against the target switch's compatibility guide.
