The 48 Core Fibre Closure with Mid Span is an outdoor fibre optic splice enclosure designed to protect, organize and manage up to 48 optical fibre connections while allowing technicians to access selected fibres from a continuous backbone cable without cutting every fibre in the cable.
Mid-span access is particularly useful in FTTH, ISP and telecommunications networks where only a small number of fibres need to branch toward a new distribution point while the remaining fibres continue uninterrupted along the main route. The Fiber Optic Association describes mid-span access as opening the cable and accessing the required buffer tube or fibres while leaving the fibres that are not being dropped intact.
A 48-core closure provides protected space for fusion splices, fibre slack, buffer tubes and cable strength members. Depending on the model, closures may support inline or mid-span branching, multiple cable-entry ports and outdoor protection such as IP68. Commercial 48-core closures are available for aerial, duct, pole, wall and buried installations.
At Fiber Optics Kenya, the 48 Core Fibre Closure with Mid Span is suitable for ISPs, telecommunications contractors, FTTH installers, campus networks, CCTV fibre infrastructure and backbone fibre projects.

What Is Mid-Span Fibre Access?
Mid-span access means accessing selected fibres inside a fibre optic cable at an intermediate point along the route without completely cutting the cable.
Instead of cutting all 48 fibres, the installer opens a section of the cable jacket, identifies the required buffer tube and accesses only the fibres that need to be dropped or spliced. The remaining fibres and tubes can continue uninterrupted through the closure.
| Mid-Span Element | Function |
|---|---|
| Continuous Backbone Cable | Passes through closure |
| Cable Jacket Window | Provides fibre access |
| Selected Buffer Tube | Opened for required fibres |
| Drop Fibres | Spliced toward branch network |
| Unused Fibres | Remain uncut |
| Uncut Tubes | Stored safely inside enclosure |
| Splice Tray | Protects branch splices |
| Closure Housing | Provides environmental protection |
Why Use Mid-Span Access?
A large backbone cable may contain many fibres even when only a few fibres are required at a particular location.
For example, a 48-core fibre cable may pass through an estate where only four fibres need to feed a local FAT box. Cutting and re-splicing all 48 fibres would create unnecessary work and additional splice loss.
With mid-span access, only the required fibres are accessed.
| Method | Normal Fibre Handling |
|---|---|
| Full Cable Cut | All fibres are interrupted |
| Mid-Span Access | Only selected fibres are accessed |
| Unselected Fibres | Continue without splicing |
| Required Fibres | Branched or dropped |
| Splice Count | Reduced |
| Installation Complexity | Lower when correctly designed |
This is one of the major advantages of mid-span fibre architecture.
How a 48 Core Mid-Span Closure Works
The backbone cable enters and exits the closure while remaining continuous. A section of the outer cable sheath is carefully removed to expose the internal buffer tubes.
The installer identifies the tube containing the fibres required at that location. Only those fibres are prepared and fusion-spliced toward a branch or drop cable.
| Stage | Function |
|---|---|
| Backbone Cable Entry | Main fibre route enters closure |
| Mid-Span Window | Cable jacket opened |
| Strength Member Fixing | Secures backbone cable |
| Buffer Tube Identification | Locates required fibre group |
| Unused Tubes | Remain intact |
| Selected Fibres | Prepared for branching |
| Fusion Splice | Joins fibre to branch cable |
| Splice Sleeve | Protects fusion joint |
| Splice Tray | Stores completed splice |
| Backbone Cable Exit | Main cable continues onward |
The FOA recommends keeping unneeded tubes carefully coiled and stored while isolating the tube containing the fibres that need to be spliced.
Example of a 48 Core Mid-Span Fibre Network
Consider a 48-core backbone fibre running through several locations.
| Fibre Allocation | Use |
|---|---|
| Fibres 1–4 | Branch to Building A |
| Fibres 5–8 | Branch to Building B |
| Fibres 9–12 | Reserved |
| Fibres 13–24 | Continue to Site C |
| Fibres 25–36 | Continue to Site D |
| Fibres 37–48 | Future Expansion |
At Building A, the closure might only access fibres 1–4. The remaining 44 fibres continue along the route without being cut.
Typical 48-Core Fibre Organization
| Fibre Range | Typical Group |
|---|---|
| 1–12 | Group 1 |
| 13–24 | Group 2 |
| 25–36 | Group 3 |
| 37–48 | Group 4 |
This grouping simplifies mid-span fibre identification and documentation.
Typical Fibre Colour Sequence
| Fibre | Colour |
|---|---|
| 1 | Blue |
| 2 | Orange |
| 3 | Green |
| 4 | Brown |
| 5 | Slate |
| 6 | White |
| 7 | Red |
| 8 | Black |
| 9 | Yellow |
| 10 | Violet |
| 11 | Rose |
| 12 | Aqua |
For 48-core cables, this sequence is typically repeated across different tubes or bundles. The actual manufacturer's colour code should always be followed.

| All Fibres Spliced | No | Usually Yes |
| Network Expansion | Excellent | Moderate |
| FTTH Distribution | Excellent | Good |
| Backbone Repair | Less Common | Excellent |
Typical Splice Tray Configuration
| Tray Capacity | Trays Required for 48 Splices |
|---|---|
| 12 Fibre | 4 |
| 24 Fibre | 2 |
| 48 Fibre | 1 High-Capacity System |
The exact arrangement depends on the closure design. A commercial 48-core dome enclosure, for example, supports 12/24-fibre splice trays and up to 48 fibres.
Cable Entry Configuration
Mid-span closures often need more flexible cable entry than simple straight-through closures.
| Entry Arrangement | Application |
|---|---|
| 2 In / 2 Out | Basic inline and branching |
| 3 In / 3 Out | Multiple branch cables |
| 4+ Ports | Larger distribution network |
| Oval Mid-Span Port | Allows continuous cable loop |
| Round Drop Ports | Branch or distribution cables |
Some fibre closures use six entry ports and are explicitly designed for inline or mid-span branching.
Mid-Span Cable Storage
One of the important functions of a mid-span closure is safely storing the uncut sections of fibre and buffer tube.
| Storage Requirement | Purpose |
|---|---|
| Uncut Buffer Tubes | Maintain backbone continuity |
| Fibre Slack | Allows future maintenance |
| Service Loops | Supports re-entry |
| Splice Fibres | Routes toward tray |
| Branch Cable Slack | Enables future repair |
Incorrectly bending or compressing uncut fibres can cause attenuation or fibre damage.
Fibre Bend Radius
Maintaining fibre bend radius is especially important in high-core-count mid-span installations.
A commercial 48-core closure specifies a 40 mm fibre bend radius without additional splice-tray loss, demonstrating the importance of controlled fibre routing inside the enclosure.
| Fibre Management Rule | Recommendation |
|---|---|
| Avoid Tight Bends | Maintain manufacturer limit |
| Avoid Fibre Kinks | Route smoothly |
| Store Slack Loosely | Prevent stress |
| Separate Uncut Tubes | Improve organization |
| Secure Without Crushing | Protect fibre geometry |
IP68 Protection
Many professional 48-core fibre closures provide IP68 protection.
| Protection Feature | Benefit |
|---|---|
| Dust-Tight Housing | Prevents contamination |
| Water Resistance | Protects outdoor fibre joints |
| Weather Protection | Suitable for outside plant |
| UV-Resistant Material | Helps outdoor longevity |
| Mechanical Sealing | Allows re-entry on compatible models |
A 48-core dome closure from Norden uses high-strength polycarbonate and provides IP68-rated protection, while another 48-core mechanical enclosure also specifies IP68.
Aerial Mid-Span Installation
Mid-span closures are particularly useful on aerial fibre routes.
| Feature | Benefit |
|---|---|
| Backbone Cable Continuity | Cable remains uninterrupted |
| Branch Cable Connection | Easy local distribution |
| Pole Installation | Suitable for access networks |

The 48 Core Fibre Closure with Mid Span is particularly valuable where a high-count fibre cable passes through several distribution points but only a few fibres are required at each location. Instead of cutting and re-splicing the complete backbone, technicians can open an access window in the cable, identify the required buffer tube and splice only the fibres being dropped. The FOA describes this as the standard principle behind mid-span access.
This approach can simplify FTTH and ISP network expansion because the majority of fibres remain uninterrupted while selected fibres are branched toward local distribution networks. Closures designed for mid-span branching provide cable-entry arrangements and internal storage space for continuous tubes, service loops and branch splices. Commercial closure systems with six entry ports are explicitly designed for inline or mid-span branching.
Proper cable preparation is especially important during mid-span work because technicians must expose the required fibres without damaging the fibres that continue through the network. Correct strength-member anchoring, fibre bend-radius control, splice protection and environmental sealing are therefore essential. Fiber Optics Kenya can supply the 48 Core Fibre Closure with Mid Span together with outdoor fibre cables, ADSS and armoured cables, fusion splice sleeves, fusion splicers, cable preparation tools, optical power meters, VFLs and OTDR equipment for complete installations.

It is a fibre optic splice enclosure that can protect up to 48 fibre connections while allowing selected fibres in a continuous cable to be accessed and branched without cutting every fibre.
What is mid-span fibre access?
Mid-span access involves opening the fibre cable at an intermediate point and accessing only the fibres required for a drop or branch while leaving other fibres intact.
Why use mid-span instead of cutting the whole cable?
It reduces unnecessary splicing and allows most backbone fibres to remain uninterrupted.
How many fibres can the closure handle?
A 48-core model can typically manage up to 48 fibres, depending on the exact tray and closure configuration.
Can only one fibre be accessed?
Technically, mid-span access can be used to access a small number of selected fibres while leaving others untouched.
Can several fibres be branched?
Yes. The number depends on the network design, available fibres, splice tray capacity and branch cable.
Do all 48 fibres need to be cut?
No. Avoiding this is one of the primary advantages of mid-span access.
Can unused fibres continue through the closure?
Yes. Unselected fibres can remain continuous through the enclosure.
Does the closure store uncut fibre tubes?
Mid-span-compatible closures provide space for safe routing and storage of continuous tubes and fibres.
