TP-Link TL-SM5110-SR 10GBase-SR SFP+ LC Transceiver Price in Kenya

The TP-Link TL-SM5110-SR is a high-performance 10GBase-SR SFP+ multimode fibre transceiver designed for short-range 10 Gigabit Ethernet connections between compatible switches, servers, routers and other network equipment.

It operates at 850nm, provides a 10Gbps data rate, uses a duplex LC fibre interface, and supports multimode fibre including 50/125µm and 62.5/125µm cable. TP-Link specifies transmission distances of up to 300 metres using suitable 50/125µm fibre such as OM3, while 62.5/125µm fibre is supported over substantially shorter distances of approximately 33 metres.

The TL-SM5110-SR also supports Digital Diagnostic Monitoring (DDM), SFF-8472, SFP+ MSA and hot-swappable installation. TP-Link lists it for use with 10G SFP+ switches including models such as the JetStream TL-SG3428X and TL-SG3428XMP. 

TP-Link TL-SM5110-SR Specifications

TP-Link's current datasheet confirms 850nm operation, IEEE 802.3ae, 10Gbps, LC duplex, 3.3V, DDM, SFP+ MSA and multimode fibre support.

What Is the TP-Link TL-SM5110-SR?

The TL-SM5110-SR is an optical transceiver that plugs into a compatible:

10G SFP+ port

and provides a:

10 Gigabit multimode fibre connection.

A typical network connection is:

10G Switch → TL-SM5110-SR → Duplex Multimode Fibre → TL-SM5110-SR → 10G Switch

Unlike BiDi modules, which can use a single fibre strand, the TL-SM5110-SR uses conventional duplex optical transmission with separate fibre paths for transmit and receive.

What Does 10GBase-SR Mean?

10GBASE-SR is a 10 Gigabit Ethernet optical standard designed primarily for short-range multimode fibre networks.

The name can be broken down as:

10G = 10 Gigabit Ethernet
BASE = Baseband Ethernet
SR = Short Reach

The TL-SM5110-SR follows IEEE 802.3ae and is designed specifically for short-distance 10Gbps optical links.

10Gbps Ethernet Speed

The TL-SM5110-SR supports:

10Gbps

network connectivity.

That is approximately ten times the nominal Ethernet bandwidth of a standard 1Gbps SFP connection.

This makes the module suitable for:

• Core network uplinks

• Distribution switches

• Data centres

• Server connectivity

• Storage networks

• High-capacity CCTV networks

• ISP aggregation

• Campus fibre backbones

850nm Wavelength

The TL-SM5110-SR operates at:

850nm

which is commonly used for short-range multimode optical Ethernet links.

TP-Link officially specifies an 850nm wavelength for the transceiver. 

Multimode Fibre Support

The TL-SM5110-SR is designed for:

Multimode Fibre – MMF

rather than single-mode fibre.

TP-Link lists support for:

50/125µm

and:

62.5/125µm

multimode fibre.

50/125µm Multimode Fibre

Modern multimode fibre such as:

• OM2

• OM3

• OM4

typically uses a 50µm core with 125µm cladding.

TP-Link specifically lists a maximum cable distance of 300m using suitable 50/125µm fibre, with its product page identifying OM3 for the full 300m specification. 

62.5/125µm Multimode Fibre

Older multimode installations may use:

62.5/125µm

fibre.

TP-Link specifies approximately:

33 metres

for TL-SM5110-SR operation over 62.5/125µm multimode cable.

This is an important consideration when upgrading an older fibre infrastructure to 10Gbps.

Up to 300m Transmission Distance

The TL-SM5110-SR supports distances of up to:

300 metres

when used with suitable 50/125µm multimode fibre.

TP-Link specifically lists:

300m with OM3

on its current product page. 

Actual performance depends on:

• Fibre category

• Fibre modal bandwidth

• Connector losses

• Splice losses

• Patch cords

• Fibre condition

• Connector cleanliness

Why Fibre Type Matters at 10Gbps

Two multimode fibre cables can have the same 50/125µm physical dimensions but different performance characteristics.

For example, an older multimode cable may not reliably support the same 10G distance as modern OM3 fibre.

Before installing TL-SM5110-SR modules on an existing fibre route, verify:

Fibre category + Distance + Connector type + Link loss

rather than checking only the fibre core size.

LC Duplex Connector

The TL-SM5110-SR uses:

LC Duplex

connectivity.

TP-Link's current datasheet identifies the port as LC Duplex, while regional product pages commonly describe it as LC/UPC.

The interface contains two optical paths:

Tx → Transmit

and

Rx → Receive

How Many Fibre Strands Does TL-SM5110-SR Need?

A conventional TL-SM5110-SR connection uses:

2 fibre strands

One strand carries traffic in one direction and the second carries traffic in the opposite direction.

This differs from single-fibre BiDi modules such as TL-SM321A/TL-SM321B.

The TP-Link TL-SM5110-SR provides a practical upgrade path from standard Gigabit fibre to 10 Gigabit Ethernet within offices, server rooms, data centres and campus environments. When suitable multimode fibre is already installed, upgrading the transceivers and network equipment can provide significantly higher backbone capacity without replacing the entire cable infrastructure.

Its 850nm 10GBASE-SR optical system is optimized for relatively short fibre routes. With suitable 50/125µm OM3 cabling, TP-Link specifies links of up to approximately 300 metres, making the module well suited to connections between racks, floors, server rooms and nearby buildings.

The module also provides Digital Diagnostic Monitoring, SFP+ MSA compatibility and hot-swappable installation, which are valuable for enterprise and ISP networks where optical monitoring, maintenance flexibility and interoperability are important.

Digital Diagnostic Monitoring – DDM

The TL-SM5110-SR supports:

DDM – Digital Diagnostic Monitoring

TP-Link specifies compatibility with:

SFF-8472. 

On compatible switches, DDM can provide information such as:

• Transmit optical power

• Receive optical power

• Module temperature

• Supply voltage

• Laser bias current

Why DDM Is Important

DDM helps network technicians diagnose optical problems.

For example, unusually low received power may indicate:

• Dirty LC connectors

• Excessive fibre attenuation

• Poor patch cords

• Fibre bends

• Damaged fibre

• Connector problems

This can make troubleshooting faster than relying only on whether the Ethernet link is up or down.

SFF-8472 Support

TP-Link lists:

SFF-8472

among the standards supported by the module.

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

SFP+ MSA Compatibility

The TL-SM5110-SR complies with:

10G SFP+ Multi-Source Agreement – SFP+ MSA

TP-Link explicitly lists SFP+ MSA compatibility. 

This establishes standardized mechanical and electrical SFP+ characteristics.

However, actual compatibility should still be verified against the host switch.

Hot-Swappable Design

The TL-SM5110-SR is:

Hot Swappable

which provides greater flexibility when adding, replacing or servicing transceivers in supported network equipment.

Always follow the network equipment manufacturer's recommended installation procedure.

TP-Link TL-SM5110-SR Switch Compatibility

TP-Link states that the transceiver is compatible with switches containing standard:

10G SFP+ ports

and specifically gives examples such as:

• JetStream TL-SG3428X

• TL-SG3428XMP

and other compatible models. 

TL-SM5110-SR with Omada Switches

The newer SM5110-SR is also represented within TP-Link's Omada networking range.

It provides a convenient option for high-speed uplinks between compatible Omada switches.

Typical topology:

Omada Access Switch
↓
10G SFP+
↓
TL-SM5110-SR
↓
OM3 Duplex Fibre
↓
TL-SM5110-SR
↓
Core Switch

TL-SM5110-SR for Switch-to-Switch Connections

The module is ideal for linking two network switches at 10Gbps.

Example:

Distribution Switch
↓
TL-SM5110-SR
↓
Duplex OM3 Fibre
↓
TL-SM5110-SR
↓
Core Switch

This is useful where 1Gbps uplinks have become a bottleneck.

TL-SM5110-SR for Data Centres

10GBASE-SR is commonly suited to data centre environments because many connections are relatively short.

Typical applications include:

• Rack-to-rack links

• Top-of-rack to aggregation switch

• Server to switch

• Storage network

• Core-to-distribution connectivity

• Virtualization infrastructure

TL-SM5110-SR for Servers

A compatible server fitted with a 10G SFP+ network interface can communicate through TL-SM5110-SR optics.

Example:

10G Server NIC → TL-SM5110-SR → OM3 Fibre → TL-SM5110-SR → Network Switch

This can provide significantly more bandwidth than a conventional 1Gbps server connection.

TL-SM5110-SR for CCTV Networks

High-resolution CCTV deployments can generate substantial network traffic.

A 10Gbps backbone can be useful when aggregating traffic from:

• Multiple PoE switches

• Large numbers of IP cameras

• 4K cameras

• NVR systems

• Central surveillance rooms

The individual cameras do not need 10Gbps interfaces; the 10G optical link is typically used as an aggregated backbone.

TL-SM5110-SR for Campus Networks

The module can connect high-capacity network switches within a campus where the fibre route is within the supported multimode distance.

Suitable environments include:

• Universities

• Schools

• Hospitals

• Business parks

• Government offices

• Hotels

• Industrial facilities

TL-SM5110-SR for ISP Networks

ISPs can use 10G SR optics for short internal and aggregation connections such as:

• Rack interconnection

• POP equipment

• Core-to-distribution links

• Server connections

• Short switch uplinks

For long external routes, a 10G LR or longer-distance module is normally more appropriate.

TL-SM5110-SR vs TL-SM311LM

TL-SM5110-SR vs TL-SM311LS

TL-SM5110-SR vs 10GBase-LR

If your fibre link is several kilometres long, TL-SM5110-SR is not the correct transceiver. A suitable 10GBASE-LR or longer-range module should be selected.

TL-SM5110-SR vs 10G BiDi SFP+

TL-SM5110-SR vs SFP

A standard:

SFP

module is most commonly associated with Gigabit optical Ethernet.

The TL-SM5110-SR uses:

SFP+

for 10Gbps Ethernet.

Although SFP and SFP+ are physically similar, they are not automatically interchangeable at every speed.

Can TL-SM5110-SR Work in a 1G SFP Port?

No, not as a 10Gbps link.

The host equipment must have a compatible:

10G SFP+ port

to use the module at its designed data rate.

Can a 1G SFP Work in a 10G SFP+ Port?

Some SFP+ ports support 1G SFP modules, while others do not.

This is determined by the host device rather than by the TL-SM5110-SR.

Always check the switch documentation.

Full Duplex 10G Ethernet

TP-Link states that the TL-SM5110-SR supports:

Full-duplex 10G Ethernet connections.

This allows simultaneous transmission and reception across the duplex fibre pair.

OM3 Fibre with TL-SM5110-SR

For the full published:

300m

distance, TP-Link specifies:

OM3 multimode fibre. 

OM3 is therefore a strong choice for new TL-SM5110-SR installations requiring significant 10G reach.

OM1 Fibre with TL-SM5110-SR

Older 62.5/125µm multimode fibre is associated with much shorter 10G distances.

TP-Link lists only:

33m

for its 62.5/125µm cable specification.

Therefore, older multimode infrastructure should be assessed carefully before a 10G upgrade.

Do Not Assume All Multimode Fibre Supports 300m

The module may be capable of 300m, but the installed fibre must also support that performance.

Before deployment, determine:

• Fibre category

• Fibre length

• Connector condition

• Number of patch points

• Existing attenuation

• Transceiver compatibility

Optical Link Loss

Even short fibre routes have optical loss.

Common sources include:

• Connectors

• Fibre adapters

• Fusion splices

• Patch cords

• Fibre bends

• Contamination

• Cable damage

A route should be properly tested where reliability is critical.

Cleaning LC Connectors

Always clean fibre connectors before inserting them into the transceiver.

Contamination can cause:

• Increased attenuation

• Unstable links

• Low Rx power

• Packet errors

• Complete loss of link

Testing TL-SM5110-SR Fibre

Optical Power Meter

An Optical Power Meter helps determine the actual optical level reaching the receiving transceiver.

OTDR

An OTDR can help identify:

• Fibre distance

• Connector events

• Splices

• Fibre breaks

• Reflective faults

• Macrobends

• High-loss sections

VFL

A Visual Fault Locator can help with basic continuity checking and fibre identification, although it does not replace proper 10G certification or optical testing.

3.3V Power Supply

The TL-SM5110-SR uses:

3.3V

from the host SFP+ port.

No separate external power supply is required for the module itself.

Operating Temperature

TP-Link specifies an operating temperature of:

0°C to 70°C.

This is a standard commercial-temperature operating range.

Storage Temperature

The 2024 SM5110-SR datasheet specifies:

-40°C to 85°C

for storage.

Some regional product pages list storage to -40°C to 80°C, so the exact hardware revision documentation should be used where environmental limits are critical.
