TP-Link SM6110-SR 25GBase-SR SFP28 LC Transceiver Price in Kenya

The TP-Link Omada SM6110-SR is a high-performance 25GBase-SR SFP28 multimode optical transceiver designed for high-speed data centres, enterprise networks, ISP infrastructure, server connections and network backbones.

It operates at 850nm and supports dual data rates of 25.78Gbps and 10.31Gbps. At 25.78Gbps, TP-Link specifies transmission distances of up to 70 metres over OM3 multimode fibre and 100 metres over OM4 multimode fibre. At 10.31Gbps, it can reach up to 300 metres over OM3 fibre. 

The SM6110-SR uses a duplex LC/UPC connector, supports Digital Diagnostic Monitoring (DDM), is hot-swappable, operates from 3.3V and consumes no more than approximately 1W.

TP-Link SM6110-SR Technical Specifications

TP-Link's current V1.20 documentation confirms the 850nm wavelength, dual 25.78Gbps/10.31Gbps data rates, duplex LC/UPC connector, multimode fibre, DDM, SFP28 MSA and hot-swappable operation. 

What Is the TP-Link SM6110-SR?

The SM6110-SR is an optical transceiver designed to convert a compatible network device's:

25G SFP28 interface

into:

25 Gigabit Ethernet over multimode fibre.

A typical connection is:

25G Switch
↓
SM6110-SR
↓
Duplex OM4 Fibre
↓
SM6110-SR
↓
25G Switch

It can also operate at approximately 10Gbps in supported host equipment, making it a dual-rate transceiver rather than a strictly 25G-only optical module.

What Does 25GBase-SR Mean?

The name can be broken down as follows:

25G = 25 Gigabit Ethernet

BASE = Baseband Ethernet transmission

SR = Short Reach

25GBASE-SR is therefore intended for high-speed short-distance optical links over multimode fibre.

TP-Link's module operates at 850nm, which is a common wavelength for short-range multimode Ethernet. 

25.78Gbps Data Rate

The SM6110-SR supports a signalling rate of:

25.78Gbps

for 25 Gigabit Ethernet operation.

This makes it suitable for networks requiring much higher bandwidth than standard:

• 1Gbps SFP

• 10Gbps SFP+

• Gigabit copper Ethernet

A 25G interface is particularly valuable for modern servers, virtualization environments, storage systems and aggregation networks.

Dual-Rate 25G and 10G Support

One of the strongest features of the SM6110-SR is its:

Dual Rate 25.78Gbps / 10.31Gbps support.

TP-Link officially specifies both rates. 

This means the transceiver may be used in compatible:

25G SFP28 ports

and selected:

10G SFP+ environments

provided the host equipment supports the module and desired operating rate.

850nm Wavelength

The SM6110-SR operates at:

850nm

over multimode fibre. 

850nm is commonly used in:

• Data centres

• Server rooms

• Enterprise networks

• Short campus links

• Rack-to-rack fibre

• High-speed multimode backbones

Multimode Fibre

The module is specifically designed for:

MMF – Multimode Fibre

rather than single-mode fibre.

TP-Link lists support for:

50/125µm or 62.5/125µm multimode fibre. 

For new 25G installations, OM3 or OM4 fibre should normally be considered, with OM4 providing the longer published 25G reach.

OM3 Fibre with SM6110-SR

At:

25.78Gbps

TP-Link specifies up to:

70 metres using OM3 fibre. 

At:

10.31Gbps

the same module can support:

up to 300 metres over OM3. 

This difference is important when upgrading an existing 10G OM3 network to 25G.

OM4 Fibre with SM6110-SR

For 25G operation, TP-Link specifies:

up to 100 metres over OM4 multimode fibre. 

OM4 is therefore the better choice when the link requires close to the maximum supported 25G distance.

Maximum Distance at Different Speeds

These are the current published TP-Link distances.

Why Does 25G Have a Shorter Reach Than 10G?

Higher data rates place greater demands on:

• Fibre modal bandwidth

• Signal quality

• Transmitter performance

• Receiver performance

• Connector cleanliness

• Overall optical link quality

Therefore, the same OM3 fibre that supports approximately:

300m at 10G

may support only:

70m at 25G

with this transceiver. 

Duplex LC/UPC Connector

The SM6110-SR uses:

Duplex LC/UPC

connectivity. 

This means the link uses two optical paths:

Tx → Transmit

and:

Rx → Receive

A common patch cord would therefore be:

LC/UPC to LC/UPC Duplex OM3 or OM4 patch cord.

How Many Fibre Strands Does SM6110-SR Need?

The module uses:

2 fibre strands

for a standard connection.

One strand carries transmission in one direction while the other carries transmission in the opposite direction.

This differs from a BiDi transceiver, where both directions may share a single fibre strand.

The TP-Link SM6110-SR is primarily intended for high-capacity short-range network links where 10Gbps is no longer sufficient. Its 25.78Gbps capability makes it appropriate for modern server infrastructure, aggregation switches, data-centre networks and enterprise backbones.

The module supports both 25G SFP28 and 10G SFP+ operating environments, subject to host compatibility. At 25G it reaches up to 100m over OM4, while at the 10.31Gbps rate TP-Link specifies as much as 300m over OM3. 

Its combination of DDM, hot-swappable operation, duplex LC/UPC connectivity and ≤1W power consumption makes it well suited for dense network installations where energy consumption and easy transceiver maintenance are important. 

VCSEL Transmitter

TP-Link specifies a:

VCSEL – Vertical-Cavity Surface-Emitting Laser

for the SM6110-SR transmitter. 

VCSEL technology is widely used for short-range multimode fibre Ethernet because it is well suited to 850nm operation.

PIN Receiver

The SM6110-SR uses a:

PIN receiver

for converting incoming optical signals into electrical data. 

Optical Transmitter Power

TP-Link's detailed specification gives transmitter power at 25.78Gbps of approximately:

-8.4dBm to +2.4dBm.

At 10.31Gbps, the published transmitter range is approximately:

-7.3dBm to -1dBm.

These figures are useful when designing or troubleshooting the optical link.

Receiver Sensitivity

TP-Link specifies receiver sensitivity of approximately:

better than -10.3dBm at 25.78Gbps

and:

better than -11.1dBm at 10.31Gbps. 

Actual received power should remain within the transceiver's supported optical operating range.

Optical Link Budget

Even though the module is rated for particular distances, network performance still depends on total optical loss.

The fibre link budget can be affected by:

Fibre attenuation + connector loss + patch-cord loss + adapter loss + splice loss + engineering margin

For high-speed 25G networks, poor connectors or dirty LC interfaces can significantly affect performance.

Digital Diagnostic Monitoring – DDM

The SM6110-SR supports:

DDM – Digital Diagnostic Monitoring. 

Depending on the host equipment, DDM can provide information including:

• Optical transmit power

• Optical receive power

• Module temperature

• Supply voltage

• Laser bias

These measurements can assist with troubleshooting.

SFF-8472 Support

TP-Link lists:

SFF-8472

among the supported standards. 

This is closely associated with diagnostic monitoring functionality in SFP-family transceivers.

SFF-8402 Support

The module supports:

SFF-8402.

SFF-8431 Support

TP-Link also lists:

SFF-8431. 

SFF-8432 Support

The module additionally supports:

SFF-8432.

Together these specifications help define mechanical and electrical interoperability for the transceiver.

SFP28 MSA Compatibility

The SM6110-SR supports:

SFP28 MSA

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

However, MSA compliance does not guarantee that every network switch from every manufacturer will accept the module.

Always verify exact host compatibility.

Hot-Swappable Operation

The module is:

Hot Swappable / Hot Pluggable. 

This allows supported equipment to accept module installation or replacement without replacing the entire switch.

Low Power Consumption

TP-Link specifies power consumption of:

no more than approximately 1W. 

This is particularly useful in high-density switches containing many optical transceivers.

3.3V Power Supply

The SM6110-SR operates from:

3.3V

supplied by the host SFP28/SFP+ port. 

No external power adapter is required.

Class 1 Laser

TP-Link classifies the SM6110-SR as:

Class 1 laser equipment.

Even so, fibre optic safety procedures should always be followed.

Never stare directly into an operating transceiver or optical fibre.

SM6110-SR Switch Compatibility

TP-Link specifically identifies compatibility with 25G switches such as:

SX6632YF

and selected 10G switches including:

SG3428X

and:

SG3452X. 

The exact port configuration and firmware should still be checked before deployment.

A 25G backbone may be appropriate when combining traffic from:

• Hundreds of IP cameras

• Multiple NVRs

• Video analytics systems

• Recording servers

• High-resolution 4K or 8K cameras

SM6110-SR vs SM6110-LR

TP-Link lists the SM6110-LR as the complementary long-distance 25G option, with a 1310nm single-mode specification and a reach of up to 10km. 

SM6110-SR vs SM5110-SR

SM6110-SR vs 25G DAC

A 25G DAC provides a direct electrical connection between two SFP28 interfaces.

Choose a DAC when:

• Equipment is in the same rack.

• Distance is very short.

• Both devices use SFP28.

Choose SM6110-SR when:

• Optical fibre is already installed.

• Electrical isolation is desirable.

• Distance exceeds practical DAC length.

• Patch-panel-based cabling is preferred.

SM6110-SR vs 10GBase-SR

The SM6110-SR offers approximately:

2.5× the nominal bandwidth

of a 10Gbps transceiver.

This makes it a logical upgrade where:

• 10G uplinks are becoming saturated.

• Server traffic has increased.

• Storage throughput is expanding.

• Network aggregation requires more capacity.

SFP28 vs SFP+

The SM6110-SR uses:

SFP28

for 25G operation.

SFP28 maintains a form factor similar to SFP+ but supports higher signalling rates.

The module is unusual in that TP-Link also specifies:

10.31Gbps SFP+ compatibility

in supported environments. 

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

Potentially yes.

TP-Link explicitly lists compatibility with selected 10G switches including SG3428X and SG3452X and specifies a 10.31Gbps operating mode.

However, compatibility should be checked with the exact switch.

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

Yes.

That is its primary intended application.

Can It Work in a 1G SFP Port?

No, not for its intended operation.

Use an appropriate Gigabit SFP module instead.

Can It Work in a 100G QSFP28 Port?

Not directly.

A QSFP28 interface uses a different physical transceiver form factor.

Some switches may support breakout arrangements, but that depends on the specific device and cabling architecture.

Does SM6110-SR Use Single-Mode Fibre?

No.

It is a:

multimode fibre transceiver.

For single-mode 25G connections, consider the SM6110-LR.

Can SM6110-SR Work Over 1KM?

No.

Its maximum published 25G reach is:

100m on OM4

and its maximum published 10G reach is:

300m on OM3. 

For kilometre-scale links, use a suitable single-mode module.

Can SM6110-SR Work Over 100m at 25G?

TP-Link rates:

100m on OM4

at 25.78Gbps. 

A design beyond this distance should use a suitable longer-reach transceiver.

Fibre Cleaning for 25G

Connector cleanliness becomes increasingly important at high data rates.

Before connecting LC fibres:

• Clean the connector.

• Inspect where possible.

• Keep dust caps installed until use.

• Avoid touching fibre end faces.

Dirty LC connectors can cause intermittent 25G problems even when a lower-speed link previously worked.

Optical Power Meter

An Optical Power Meter can help verify the received optical level.

This is useful when diagnosing:

• Excessive optical loss

• Poor patch cords

• Connector problems

• Fibre attenuation

OTDR Testing

An OTDR can help identify:

• Fibre length

• Bad splices

• Reflective connectors

• Fibre breaks

• Macrobends

• High-loss events

VFL Testing

A Visual Fault Locator can assist with:

• Fibre identification

• Continuity checking

• Locating visible breaks

A VFL does not certify the fibre for 25Gbps Ethernet performance.

Operating Temperature

TP-Link specifies:

0°C to 70°C.

Storage Temperature

The storage specification is:

-40°C to 85°C.

Dimensions
