4 Core OM4 Fibre Optic Cable 50/125 in Kenya

The 4 Core OM4 Fibre Optic Cable 50/125 is a high-performance laser-optimized multimode fibre cable designed for modern high-speed network environments. With four OM4 optical fibres, it provides reliable connectivity for enterprise LANs, server rooms, data centres, campus networks, CCTV systems and building-to-building fibre links where high bandwidth and low latency are required.

OM4 uses a 50 µm core and 125 µm cladding and is optimized for 850 nm laser transmission. It provides significantly higher modal bandwidth than earlier multimode fibre generations, making it suitable for high-speed applications such as 10 Gigabit Ethernet and short-reach 40G/100G networks. Corning identifies OM4 as a 50/125 µm laser-optimized multimode fibre, while CommScope notes that OM4 provides substantially greater bandwidth than OM3. 

At Fiber Optics Kenya, we supply 4 Core OM4 Fibre Optic Cable for ICT contractors, network installers, businesses, schools, hospitals, hotels, data centres and institutions across Kenya. The cable can be supplied together with compatible pigtails, patch cords, ODFs, adapters, SFP/SFP+ modules and other accessories required to create a complete multimode fibre installation.

Key Product Specifications

Corning and CommScope both list OM4 as 50/125 µm multimode fibre, and CommScope offers OM4 in indoor/outdoor, loose-tube and armoured cable constructions. 

What Is OM4 Fibre?

OM4 is a laser-optimized multimode optical fibre developed for high-speed short-reach networking. It offers greater modal bandwidth than OM3 and is commonly deployed in enterprise and data-centre environments.

OM4 provides substantially more bandwidth than OM3, which is why it is commonly selected where additional performance margin or higher-speed upgrades are important. 

4 Core OM4 Fibre Cable Construction

A 4-core OM4 cable contains four separate multimode optical fibres protected by cable components appropriate to the intended installation environment.

Corning's 4-fibre OM4 tight-buffered products use dielectric strength members surrounding individually buffered fibres, demonstrating a common indoor cable architecture.

OM4 Technical Performance

Corning documentation notes OM4 suitability up to 550 m in applicable multimode applications, while IEEE-based 40G/100G architectures commonly specify 150 m over OM4. Exact reach depends on the transceiver and Ethernet standard being used. 

OM4 vs OM3 Fibre Optic Cable

OM4 offers approximately 2.35 times the modal bandwidth of OM3, according to CommScope, providing additional performance margin for demanding network environments. 

Why Choose a 4 Core OM4 Cable?

A four-core cable provides more flexibility than a simple two-fibre link while remaining compact and economical.

Alternatively, the four fibres can be allocated to separate simplex optical services depending on network architecture.

Primary Connection + Backup

Two fibres can operate the main duplex network connection while the remaining two are reserved for backup.

Two Independent Duplex Links

Four fibres can support two conventional duplex optical connections.

Future Expansion

Unused fibres can remain available for an additional link instead of requiring installation of another cable later.

The 4 Core OM4 Fibre Optic Cable 50/125 is designed for high-performance network environments where data must move quickly between switches, servers, network cabinets and other optical equipment. OM4's laser-optimized 50/125 µm construction provides higher modal bandwidth than earlier multimode fibre generations, making it particularly well suited to modern enterprise LAN and data-centre infrastructure. Corning identifies OM3/OM4 50/125 µm connectivity as a primary technology for high-performance server and storage links. 

The four-fibre configuration also gives network designers useful flexibility. Two fibres can operate a conventional duplex connection while two remain available for redundancy, or all four fibres can be used to create two independent duplex links. This makes 4 Core OM4 an attractive option for server rooms, offices, schools, hospitals and commercial facilities where additional capacity may be required later.

When purchasing OM4 cable, the physical cable construction should be matched to the installation environment. Indoor cables can use tight-buffered LSZH or PVC construction, while outdoor or indoor/outdoor versions may use loose tubes, water-blocking elements, black jackets or armour. Fiber Optics Kenya can help customers select the appropriate OM4 cable, connectors and transceivers for their specific route and network equipment. 

Applications of 4 Core OM4 Fibre Optic Cable

1. Data Centres

OM4 is particularly suitable for high-speed links between servers, switches and storage equipment.

2. Enterprise LAN Networks

Use OM4 to create high-bandwidth backbone links between telecommunications rooms and network cabinets.

3. Server Rooms

Connect servers, core switches, aggregation switches and storage systems using high-speed multimode optics.

4. Building Backbone Networks

Four-core OM4 can provide redundant or dual fibre links between different network distribution points.

5. CCTV Networks

Use OM4 as the backbone between CCTV network switches and central monitoring systems where distances remain within multimode limits.

6. Schools and Universities

Connect ICT laboratories, server rooms, libraries and other network areas.

7. Hospitals

Suitable for high-speed backbone links between departments and network cabinets.

8. Hotels

Connect server rooms, CCTV infrastructure, Wi-Fi distribution systems and communications equipment.

9. Industrial Networks

Fibre can provide reliable high-bandwidth communications while remaining immune to electromagnetic interference.

10. Commercial Buildings

Create high-speed fibre links between floors, offices and network distribution rooms.

OM4 vs Single Mode Fibre

Indoor vs Outdoor OM4 Fibre

CommScope lists OM4 in indoor/outdoor loose-tube and armoured constructions, illustrating that OM4 fibre is not restricted to indoor aqua-jacketed cable. 

Armoured vs Non-Armoured 4 Core OM4 Cable

A commercially available four-fibre OM4 steel-wire-armoured cable, for example, is designed for LAN/WAN backbones, telecom access lines and building connections while providing added mechanical protection.

Compatible Fibre Optic Connectors

For many modern OM4 installations, LC duplex is commonly used with SFP/SFP+ transceivers, while MTP/MPO connectivity is used in certain parallel-optics 40G and 100G architectures.

Recommended Accessories

Fiber Optics Kenya can supply OM4 cable together with compatible network accessories.

4 Core OM4 vs 2 Core OM4

For many new installations, selecting four cores instead of two can provide useful spare capacity without greatly increasing the complexity of the installation.

Why Buy from Fiber Optics Kenya?

Selecting an OM4 cable involves more than simply looking for an aqua or violet jacket. The fibre standard, cable construction, transceiver type, network speed, distance and installation environment must all be compatible.

Frequently Asked Questions

What is 4 Core OM4 Fibre Optic Cable?

It is a multimode fibre cable containing four OM4 50/125 µm optical fibres designed for high-speed short-reach networks.

What does 50/125 mean?

Is OM4 better than OM3?

OM4 provides higher modal bandwidth and additional transmission reach for several high-speed Ethernet applications. 

Is OM4 suitable for 10 Gigabit Ethernet?

Yes. OM4 is well suited to 10 Gigabit Ethernet and can support distances beyond those generally associated with OM3 when compatible optics are used. 

Can OM4 support 40G?

Yes. Standard parallel-optics 40G applications can support approximately 150 m over OM4, depending on the optical standard and equipment.

Yes. OM4 supports applicable short-reach 100G architectures, with the exact distance determined by the transceivers and Ethernet specification.

Can four fibres provide two connections?

Yes. If each duplex connection uses two fibres, four fibres can provide two independent duplex links.

What colour is OM4 cable?

OM4 is commonly identified with aqua or violet jackets in indoor cabling. Outdoor OM4 cable can have a black jacket, so the actual fibre specification should always be checked.
