The TP-Link Omada SM6110-LR is a high-performance 25GBase-LR SFP28 single-mode fibre transceiver designed for high-speed, long-distance network connections in data centres, enterprise networks, ISP infrastructure, campus networks and server environments.

It supports dual data rates of 25.78Gbps and 10.31Gbps, operates at a 1310nm wavelength, uses 9/125µm single-mode fibre, and can transmit data over distances of up to 10 kilometres. TP-Link describes it as a dual-rate 10G/25GBASE-LR SFP+/SFP28 transceiver. 

The SM6110-LR uses a duplex LC/UPC connector, supports Digital Diagnostic Monitoring (DDM), complies with SFP28 MSA requirements, and is hot-swappable. TP-Link's current V1.20 datasheet also specifies low power consumption of no more than 1.2W.

TP-Link SM6110-LR Technical Specifications

TP-Link's current V1.20 datasheet confirms the 1310nm wavelength, 9/125µm single-mode fibre, 10km reach, dual 10.31/25.78Gbps data rate, duplex LC/UPC, DDM, SFP28 MSA and hot-swappable operation.

What Is the TP-Link SM6110-LR?

The SM6110-LR is an optical transceiver designed to convert a compatible:

25G SFP28 interface

into:

25 Gigabit Ethernet over single-mode fibre.

A typical installation is:

25G Switch
↓
SM6110-LR
↓
Duplex OS2 Single-Mode Fibre
↓
SM6110-LR
↓
25G Switch

The module can also operate at the lower 10.31Gbps rate when installed in compatible 10G equipment. TP-Link specifically describes it as supporting both 10G and 25G Ethernet. 

What Does 25GBase-LR Mean?

The product name can be broken down as:

25G = 25 Gigabit Ethernet

BASE = Baseband Ethernet

LR = Long Reach

The LR designation indicates that the transceiver is designed for considerably longer fibre distances than a short-range multimode SR module.

The SM6110-LR operates over:

9/125µm single-mode fibre

at:

1310nm

and supports distances up to:

10KM.

25.78Gbps Data Rate

The maximum supported signalling rate is:

25.78Gbps

for 25 Gigabit Ethernet operation.

This provides considerably more bandwidth than:

• 1Gbps SFP

• 10Gbps SFP+

• Standard Gigabit copper Ethernet

TP-Link also specifies:

10.31Gbps

as a supported secondary operating rate. 

Dual-Rate 25G and 10G Support

One of the most important features of the SM6110-LR is its:

Dual Rate 25.78Gbps / 10.31Gbps support.

This means that, subject to the host device, the same module can operate with:

25G SFP28 equipment

or selected:

10G SFP+ equipment.

TP-Link specifically lists compatibility with 25G switches such as the SX6632YF and 10G switches such as SG3428X and SG3452X. 

1310nm Wavelength

The SM6110-LR operates at:

1310nm

over single-mode fibre. 

1310nm is commonly used in longer-range Ethernet applications because single-mode fibre provides low attenuation and supports kilometre-scale connections.

Single-Mode Fibre

The SM6110-LR is designed for:

9/125µm Single-Mode Fibre – SMF.

TP-Link specifies a maximum cable length of:

10 kilometres.

For modern installations, the typical fibre choice would be:

OS2 9/125µm single-mode fibre.

Up to 10KM Transmission Distance

The module supports transmission over distances of up to:

10KM

which is equal to approximately:

10,000 metres.

TP-Link specifies the same maximum distance for the module's supported 10G and 25G Ethernet operation over appropriate 9/125µm fibre. 

Why 10KM Fibre Reach Matters

A 10km optical connection makes the SM6110-LR suitable for much more than short server-room connections.

Potential applications include:

• Building-to-building links

• Large campuses

• ISP POP connections

• Data-centre interconnection

• Industrial sites

• Enterprise fibre backbones

• Government campuses

• Hospital networks

• University infrastructure

Duplex LC/UPC Connector

The SM6110-LR uses:

Duplex LC/UPC

connectivity.

This means that a standard connection uses two fibre strands:

Tx → Transmit

and:

Rx → Receive

A common patch cable would therefore be:

LC/UPC to LC/UPC Duplex OS2 Single-Mode Fibre Patch Cord.

How Many Fibre Strands Does SM6110-LR Need?

The module requires:

2 fibre strands

for a normal point-to-point optical connection.

One fibre carries data in one direction while the other carries traffic in the opposite direction.

This differs from BiDi transceivers, which can transmit and receive over a single fibre core.

The TP-Link SM6110-LR combines high bandwidth with long-distance single-mode fibre transmission. Its ability to operate at both 10G and 25G makes it useful for organizations that are migrating from existing 10Gbps infrastructure toward 25Gbps networking.

Unlike the SM6110-SR, which uses 850nm multimode fibre for short links, the LR version operates at 1310nm over 9/125µm single-mode fibre and supports distances up to 10km. This makes it better suited to building-to-building, campus, ISP and long enterprise backbone applications. 

The transceiver also supports DDM, hot-swappable operation and 10G/25G SFP+/SFP28 MSA compatibility, while keeping power consumption to no more than approximately 1.2W.

Digital Diagnostic Monitoring – DDM

The SM6110-LR supports:

Digital Diagnostic Monitoring – DDM. 

On compatible switches, DDM can provide diagnostic parameters such as:

• Transmit optical power

• Receive optical power

• Module temperature

• Supply voltage

• Laser bias information

These measurements can assist technicians when diagnosing fibre problems.

Why DDM Is Important

Without DDM, a network administrator may only know whether the fibre link is:

Up

or:

Down.

With DDM, it may be possible to determine whether the problem relates to:

• Low received optical power

• Excessive fibre loss

• Dirty LC connectors

• Poor splices

• Fibre bends

• A degraded module

This can substantially simplify troubleshooting on critical 25G links.

SFF-8472 Support

TP-Link lists:

SFF-8472

among the SM6110-LR standards.

SFF-8472 is associated with diagnostic monitoring functionality in pluggable transceivers.

SFF-8431 Support

The module supports:

SFF-8431.

SFF-8432 Support

TP-Link also lists:

SFF-8432.

SFF-8402 Support

The module additionally supports:

SFF-8402.

eCPRI and CPRI Support

TP-Link's specification includes:

eCPRI

and:

CPRI. 

These protocols are especially relevant to certain telecommunications and mobile-network transport applications.

SFP28 MSA Compatibility

The SM6110-LR supports:

SFP28 MSA

and TP-Link describes it as compatible with both 10G/25G SFP+/SFP28 MSA environments.

This defines standardized electrical and mechanical characteristics for the transceiver.

However, exact vendor compatibility should still be checked before deploying the module in large quantities.

Hot-Swappable Design

The SM6110-LR is:

Hot Swappable / Hot Pluggable. 

This allows supported network equipment to accept transceiver replacement or installation without replacing or powering down the entire switch.

Always follow the equipment manufacturer's recommended transceiver procedure.

Automatic 10G / 25G Operation

TP-Link's installation documentation states that the transceiver can automatically configure itself according to the host port speed:

25Gbps port → module operates at 25Gbps

10Gbps port → module changes to 10Gbps

on supported equipment. 

This makes the module particularly useful during phased network upgrades.

3.3V Power Supply

The SM6110-LR receives:

3.3V

from the host SFP28/SFP+ interface.

No separate external power adapter is required.

Low Power Consumption

TP-Link specifies power consumption of:

no more than 1.2W.

Low transceiver power consumption is beneficial in high-density switches because it reduces:

• Overall power draw

• Heat generation

• Cooling demand

Class 1 Laser

The current SM6110-LR V1.20 datasheet classifies the module as:

Class 1 laser equipment.

TP-Link specifies maximum laser output of approximately:

1.66mW / 2.2dBm.

Even with a Class 1 designation, never look directly into an active optical transceiver or connected fibre.

SM6110-LR Switch Compatibility

TP-Link specifically gives compatibility examples including:

25G switch: SX6632YF

and:

10G switches: SG3428X and SG3452X. 

Compatibility with other switches should be checked against the exact model and firmware.

SM6110-LR for 25G Switch-to-Switch Links

• Data centre links

• Distribution uplinks

• Server rooms

• Disaster recovery sites

SM6110-LR vs SM6110-SR

The key difference is therefore:

SM6110-SR = short-range multimode

while:

SM6110-LR = long-range single-mode. 

SM6110-LR vs SM5110-LR

The SM6110-LR therefore provides a logical upgrade when a 10G LR link no longer provides sufficient capacity.

SM6110-LR vs 25G DAC

A DAC is normally preferable for very short rack connections.

The SM6110-LR is better when the connection spans:

• Rooms

• Floors

• Buildings

• Campuses

• Kilometres

SM6110-LR vs 25G BiDi

A conventional SM6110-LR connection requires:

2 fibre strands.

A 25G BiDi solution typically requires:

1 fibre strand

and uses complementary transmit/receive wavelengths.

If fibre cores are scarce, an appropriate BiDi solution may be more efficient.

SFP28 vs SFP+

The SM6110-LR is primarily:

SFP28

for 25Gbps networking.

SFP28 retains a compact form factor similar to SFP+ while supporting a higher signalling rate.

This particular module also supports:

10.31Gbps

which allows operation in selected SFP+ equipment. 

Can SM6110-LR Work in a 25G SFP28 Port?

Yes.

That is its primary intended application.

Can SM6110-LR Work in a 10G SFP+ Port?

Yes, on supported equipment.

TP-Link lists compatibility with selected 10G switches and describes automatic speed adaptation between 10Gbps and 25Gbps host ports. 

Can SM6110-LR Work in a 1G SFP Port?

No.

Use an appropriate Gigabit SFP transceiver.

Can It Work in a 100G QSFP28 Port?

Not directly.

QSFP28 is a different physical form factor.

Some networking equipment supports breakout configurations, but this depends on the specific switch and breakout architecture.

Can SM6110-LR Use Multimode Fibre?

No.

It is designed for:

9/125µm single-mode fibre.

For multimode fibre, use the SM6110-SR.

OS2 Fibre for SM6110-LR

Optical Link Budget

A manufacturer's 10km rating does not mean every 10km cable installation will automatically work.

Total optical loss includes:

Cable attenuation + connectors + fusion splices + adapters + patch cords + bends + engineering margin

A poorly installed shorter link can sometimes produce more optical loss than a well-installed longer route.

Cleaning LC Connectors

Fibre connector cleanliness is extremely important at 25Gbps.

Dirty LC connectors can cause:

OTDR

An OTDR can help identify:

• Cable length

• Fibre breaks

• High-loss splices

• Reflective connectors

• Bends

• Unusual attenuation

VFL

A Visual Fault Locator can assist with:

• Fibre identification

• Continuity checks

• Visible breaks

A VFL does not certify a fibre route for 25Gbps performance.

25G Fibre Testing

For critical 25G installations, fibre should ideally be tested before commissioning.

Verification may include:

• Connector inspection

• Optical loss measurement

• OTDR testing

• End-to-end link testing
