TP-LINK compatible TL-SM311LM Description
EdgeOptic's TL-SM311LM compatible is a TP-Link-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850nm VCSEL transmitter and a PIN photodiode receiver. TL-SM311LM is TP-Link's multimode SX part; the TL-SM311LS is the separate singlemode SFP for long-reach fiber, so match the fiber type before ordering.
With a 7.5 dB optical budget, the module reaches 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m over OM1 (62.5/125). It uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live monitoring of optical power, bias current, and temperature. The module operates over the commercial 0 to 70°C range, built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.
EdgeOptic codes the EEPROM with TP-Link-recognized data so the module is accepted on TP-Link switch platforms. TP-Link documents SX SFP support across its JetStream managed switch families, including the T1500, T1600, T1700, T2500, T2600, T2700, and T3700 series, plus the MC220L media converter. Verify your platform's transceiver support table before deploying, since firmware behavior can differ across releases and on non-TP-Link host switches.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For ordering-code confirmation or platform questions, contact our sales team.
