TL-SM5110-LR TP-Link Compatible 10G SFP+ LR Module

The EdgeOptic 10G-SFP-10 is a compatible replacement for the TP-Link TL-SM5110-LR 10GBASE-LR SFP+ transceiver. It delivers 10GBASE-LR performance at 1310nm on single-mode fiber. Maximum reach is 10km via duplex LC/UPC connector. The module is coded with TP-Link vendor identification in the EEPROM, which ensures correct reporting in Omada switch management interfaces.

Transmitter uses a 1310nm DFB laser; receiver is a PIN photodiode. Link budget is 6dB over G.652 single-mode fiber. The module supports dual-rate operation at 1.25 Gbps (1000BASE-LX) and 10.3125 Gbps (10GBASE-LR, 64B/66B encoding per IEEE 802.3ae). Dual-rate 1G operation requires the port to support rate negotiation.

Compatible with TP-Link Omada managed switches including the SG3428X, SG3452X, SX3008F, SX3016F, and SX3032F series, as well as the ER8411 VPN gateway. TP-Link devices with SFP+ ports accept MSA-compliant modules. Because TP-Link does not implement vendor locking, MSA-compliant modules without TP-Link coding also function normally — the EEPROM coding provides cleaner identification in the Omada management interface.

TP-Link originally sold this module as TL-SM5110-LR under the JetStream brand. The current Omada-branded version is SM5110-LR (without the TL- prefix). Same spec, different label. The TL- prefix SKU is marked end-of-life on some regional TP-Link sites, but the Omada version remains active.

DDM per SFF-8472 reports TX/RX optical power, laser bias current, temperature, and supply voltage. MSA compliant per SFF-8431 (electrical) and IEEE 802.3ae (optical), with Class 1 laser safety per IEC 60825-1. CE and RoHS certified for commercial temperature range 0°C to 70°C.

Operates over G.652 single-mode fiber (OS1/OS2 compliant). Minimum link length is 2m; use an inline attenuator for shorter patches.

G.652 single-mode fiber has an attenuation of approximately 0.35 dB/km at 1310nm. Over a 10km span, fiber loss consumes about 3.5 dB of the optical power budget. Connector insertion loss runs 0.5 dB per mated UPC pair; fusion splices add 0.1 dB each. A 10km link with two connector pairs and a few splices consumes roughly 4.5–5 dB, leaving 1–1.5 dB of margin against the 6 dB budget.

10GBASE-LR covers enterprise and campus backbones, inter-building links, metro access and aggregation rings, carrier backhaul, and dark-fiber DCI. The 10km reach is sufficient for most metro and enterprise applications without moving to longer-reach ER or ZR optics. For spans near the 10km limit, measure installed attenuation with an OTDR or optical loss meter before commissioning.

LC connector endfaces should be inspected and cleaned before every mate. Contaminated or scratched connectors are a common cause of link degradation at 10G rates: a single particle larger than the mode field diameter can add several dB of loss. Use IEC 61300-3-35 visual inspection grading and dry or wet cleaning methods before installation.
