TP-LINK compatible TXM431-LR Description
TXM431-LR is TP-Link's part number for a 10GBASE-LR SFP+ transceiver. EdgeOptic's compatible is a direct drop-in replacement for the original module. 1310 nm wavelength over single-mode fiber, LC duplex connector, up to 10 km reach. Built on EdgeOptic's 10G-SFP-10 platform, fully compliant with IEEE 802.3ae and the SFP+ MSA standard (SFF-8431, SFF-8432).
TP-Link positions the TXM431-LR as a 10G SFP+ module for their managed switch and router portfolio. EdgeOptic programs the EEPROM with TP-Link-recognized vendor coding, so the module registers natively in TP-Link equipment without compatibility warnings or extra configuration. Data rates from 1.25 to 10.31 Gbps. Hot-pluggable, draws 3.3V from the host slot, and requires no software configuration on TP-Link platforms — insert and it initializes automatically. The module draws under 1W, standard for the 10GBASE-LR power class. 0-70 C commercial temperature range, CE/RoHS certified.
1310 nm DFB laser, 6 dB optical link budget, 9/125 um single-mode fiber (OS1 or OS2 grade). Multi-mode fiber is not supported. DOM (Digital Optical Monitoring) per SFF-8472 is included, providing real-time tracking of TX/RX optical power, temperature, supply voltage, and laser bias current from the host management interface. On TP-Link switches, DOM telemetry is accessible through TP-Link's web management GUI or SNMP, depending on the switch model. Enables early detection of degrading fiber or dirty connectors before they cause link drops.
TP-Link lists the TXM431-LR for their 10GbE switches, routers, NICs, and media converters. EdgeOptic's compatible is EEPROM-coded for TP-Link identification and hot-pluggable in any TP-Link SFP+ port. SFP+ MSA compliance means the module physically fits standard SFP+ slots on other vendors' equipment as well, though EEPROM coding is optimized for TP-Link platforms. TP-Link doesn't enforce hard vendor lock on SFP+ slots — compatible modules operate without firmware restrictions on current TP-Link firmware versions.
CE/RoHS certified, Class 1 laser safety compliant. Volume discounts available for TP-Link environments deploying multiple SFP+ modules. Part of the EdgeOptic 10G-SFP-10 product family, which includes vendor-coded 10GBASE-LR modules for all major manufacturers. Each module ships with individual test results and is backed by a lifetime warranty. For volume pricing or compatibility questions -- contact our sales team.
Frequently Asked Questions
Can the TXM431-LR be used in non-TP-Link switches?
MSA-compliant (SFF-8431/SFF-8432) and IEEE 802.3ae compliant, so it fits and operates in any standard SFP+ slot. EEPROM is coded for TP-Link. In non-TP-Link equipment, the module functions but may register as unrecognized or third-party depending on host firmware.
