TP-LINK compatible TXM431-SR Description
EdgeOptic's TXM431-SR compatible is a TP-Link-coded version of the EdgeOptic 10G-SFP-300 multi-vendor 10GBASE-SR SFP+ transceiver. TP-Link-recognized EEPROM lets the optic register cleanly on TP-Link 10G SFP+ switch cages, so the switch accepts the module without a vendor-mismatch alert. One universal SR hardware platform, 80+ vendor codes, including this TP-Link variant.
Optical specifications, 10GBASE-SR class. 850 nm VCSEL transmitter, PIN photodiode receiver, multi-mode duplex LC. Reach is 300 m on OM3 and 400 m on OM4. TX output power runs −5 to 0 dBm, receiver sensitivity −11.1 dBm, receiver overload 0 dBm, link budget 6.1 dB. Multi-rate capability spans 1.25 to 11.32 Gbps, covering 10G Ethernet, Gigabit Ethernet, 1G to 10G Fibre Channel, and STM-64. DDM/DOM supported for live link diagnostics. Compliance: SFF-8431, SFP MSA, IEEE 802.3ae, RoHS, IEC60825-1 Class 1 laser safety. Operating range 0 to 70°C commercial.
TXM431-SR is the TP-Link order code for the 10GBASE-SR SFP+ used across TP-Link's 10G smart-managed and Omada SDN-managed switch portfolio. The TXM-series is TP-Link's optical transceiver module family; the SR suffix denotes 850 nm short-reach multi-mode operation. Compatible with TP-Link TL-SX series 10G switches such as TL-SX3016F and TL-SX3008F that expose SFP+ uplink cages; verify against the TP-Link product page for your switch model for the current list of approved transceiver order codes.
Within the Omada SDN ecosystem, TXM431-SR is the TP-Link-published optic for Omada-managed deployments, so the EEPROM identifier matches what the Omada controller and the switch firmware expect during inventory and telemetry collection. Hosts that operate outside Omada and rely on SFF-8431 MSA compliance also accept this module since the optical envelope conforms to IEEE 802.3ae 10GBASE-SR.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty included.

TXM431-SR FAQ
Does the TXM431-SR compatible work in TP-Link Omada SDN-managed switches?
Yes, on Omada-managed switches that accept TP-Link-coded SFP+ optics. EdgeOptic codes this compatible with the TP-Link EEPROM identifier the Omada controller and switch firmware expect to see during inventory collection, so the optic registers cleanly on Omada-managed TL-SX series switches without third-party alerts in the controller dashboard. For Omada controller versions and switch firmware combinations that enforce stricter vendor checks, verify against the TP-Link Omada documentation for that controller release before deploying at scale.
Can the TXM431-SR compatible be used in the TP-Link TL-SX3016F or TL-SX3008F?
Yes. TXM431-SR is published by TP-Link as the SR SFP+ optic for the TL-SX series 10G smart-managed switches, including TL-SX3016F (sixteen 10G SFP+ ports) and TL-SX3008F (eight 10G SFP+ ports). The EdgeOptic compatible carries the same TP-Link EEPROM identifier so the switch lists the optic as a recognized TP-Link transceiver in the port inventory. Confirm the exact switch firmware version and the TP-Link transceiver compatibility note for that release before deployment.
