Portuguese / Português SC to SC OM4 fibre optic patch cable
DINIC SC/SC OM4 fibre optic cables for professional multimode infrastructures: pre-terminated with SC connectors at both cable ends and particularly suitable for fibre optic patch panels, floor and building distribution points, technical rooms and existing SC cabling.
The cables combine OM4 multimode 50/125 µm, a duplex configuration and an LSZH jacket. The robust SC connector with a push-pull mechanism is easy to use and has been a standard feature in professional fibre-optic installations for many years.
Available cable lengths: The SC/SC OM4 series ranges from short patch connections to longer distribution runs – currently from 2 m to 30 m.

Choosing the right SC/SC OM4 fibre-optic cable
An SC/SC OM4 fibre-optic patch cable is the right choice when SC connectors are present at both ends of a multimode connection. Typical applications include fibre optic patch panels, building and floor distribution frames, equipment rooms and existing SC-based fibre optic installations.
Before placing an order, the connector type, fibre type, duplex requirement, cable length and the optical technology used should be checked.
When is SC/SC OM4 particularly suitable?
SC patch panel to SC patch panel
For direct patch connections between two distribution frames or patch panels with SC duplex connectors.
Existing installations
Ideal where existing building cabling and distribution frames are already consistently configured with SC connectors.
Technical and distribution rooms
The larger SC connector is robust, easy to grip and, thanks to its push-pull mechanism, is simple to connect and disconnect.
What makes the SC connector special?
The SC connector features a 2.5 mm ferrule and a square design. The connection is established via a simple push-pull mechanism.
SC has been established in professional fibre-optic installations for many years and is used particularly frequently in patch panels, floor distribution frames, building distribution frames, telecommunications systems and existing networks.
SC or LC – which connector is better?
Both connector types are suitable for professional fibre-optic connections. The decisive factor is, above all, which connectors are used in the existing infrastructure.
SC – robust and easy to handle
- 2.5 mm ferrule
- larger design
- Push-pull mechanism
- commonly used in patch panels and distribution frames
- well suited to existing installations
LC – compact and high port density
- 1.25 mm ferrule
- compact design
- Locking mechanism
- Commonly used in modern transceivers
- High connection density in the rack
What does OM4 50/125 µm mean?
OM4 is a laser-optimised 50/125 µm multimode fibre. It is suitable for high-performance optical network connections in server rooms, data centres, building infrastructures and multimode backbones.
However, the possible data rate and range are not determined by OM4 alone. The decisive factors are always the combination of the Ethernet standard, the transceiver, the fibre-optic link and the optical loss budget.
What range is possible with OM4?
| Application | OM4 | Note for SC/SC |
|---|---|---|
| 10GBASE-SR | typically up to 400 m | The total link may include SC connectors; however, the specific transceiver often has LC connectors and may require LC/SC connectors at the active end. |
| 25GBASE-SR | typically up to around 100 m | 25G-SR transceivers often use LC duplex. With SC infrastructure, LC/SC may therefore be a more suitable option. |
| 40GBASE-SR4 | typically up to 150 m | Standard SR4 uses parallel optics and usually MPO/MTP – not a standard SC/SC duplex cable. |
| Other data rates | depending on the standard | Always check the optical interface and specification of the specific transceiver. |
What does ‘duplex’ mean?
The SC/SC cables in this category are designed as duplex cables with two optical fibres.
In many traditional optical Ethernet connections, one fibre is used for transmission and a second fibre for reception. The two SC connectors form the corresponding fibre pair.
Check these four points before ordering
Select SC/SC if both endpoints actually have SC connectors.
The existing link and the optical components must be compatible with 50/125 µm multimode technology.
A duplex configuration is suitable for typical two-fibre Ethernet connections.
the correct length Take into account the installation route plus a reasonable amount of spare cable; avoid unnecessarily long cable loops.
SC/SC, LC/SC or LC/LC – which variant do I need?
What does LSZH mean?
LSZH – Low Smoke Zero Halogen – refers to a halogen-free cable sheath design with reduced smoke emission.
According to the product specification, DINIC SC/SC OM4 cables in this category are halogen-free in accordance with IEC 60754-2, flame-retardant in accordance with IEC 60332-1 and low-smoke in accordance with IEC 61034. This makes them particularly suitable for professional building and IT installations.
Why is the cable erika violet?
The heather violet sheath in RAL 4003 makes it easier to visually identify OM4 connections in patch panels, plant rooms or network cabinets.
However, the colour is merely a guide. The actual OM4 50/125 µm marking is always decisive for the technical selection.
Can I connect OM4 to OM3?
OM3 and OM4 are both 50/125 µm multimode fibres and can, in principle, be connected to one another within a multimode infrastructure.
For mixed-mode runs, the range and power reserve should be based on the weaker section. For new installations, a consistent OM4 cabling system is usually easier to plan and document.
Is SC/SC OM4 the same as SC/APC for FTTH?
No. Whilst the connector type may be SC in both cases, the applications are technically different.
The SC/SC cables in this category are OM4 multimode patch cables for the corresponding network infrastructures. FTTH connections, on the other hand, typically use OS2 single-mode fibre and frequently feature green SC/APC connectors with an angled-polished ferrule.
For fibre optic routers, GF-TA and FTTH, you will find separate fibre optic patch cables for routers.
Is SC/SC OM4 suitable for outdoor installations?
The patch cables in this category are intended for typical professional indoor and in-building installations.
For conduit, campus or building-to-building runs, a robust outdoor cable design specifically intended for this purpose should be used.
You can find suitable solutions under DINIC OM4 outdoor fibre-optic cables.
Frequently asked questions about SC/SC OM4 fibre-optic cables
What is an SC/SC OM4 cable?
An SC/SC OM4 cable is a multimode fibre-optic cable with OM4 50/125 µm fibres and SC connectors at both ends of the cable.
When do I need SC to SC?
SC/SC is the right choice when both ends of the connection have SC connectors, for example two patch panels, distribution frames or network components equipped with SC connectors.
What is the difference between SC and LC?
SC uses a 2.5 mm ferrule and is larger and easier to grip. LC uses a more compact 1.25 mm ferrule and allows for higher port density.
Is SC automatically single-mode?
No. SC is simply the connector type. SC can be used with both multimode and single-mode fibre. The products in this category are OM4 multimode.
Is OM4 multimode or single-mode?
OM4 is a laser-optimised multimode fibre with a 50/125 µm core. For single-mode connections, for example, OS2 with a 9/125 µm core is used.
What is the transmission distance for OM4 at 10 Gigabit?
For 10GBASE-SR, distances of up to 400 m are typically possible using OM4. In addition, the specific transceiver, the connection points and the optical loss budget must be taken into account.
Can I connect SC/SC to an SFP+ module?
Only if the optical interface actually uses SC. Many SFP+ transceivers have LC duplex connectors. In this case, an LC/SC OM4 cable is the more suitable solution for an SC-based infrastructure.
Can I connect OM4 to OM3?
In principle, yes, as both fibre classes use 50/125 µm multimode fibre. When planning power requirements, the weaker section of the link should be taken as the basis.
Is SC/SC OM4 suitable for FTTH?
Not normally. Typical FTTH connections use OS2 single-mode fibre and frequently SC/APC or LC/APC. Special FTTH patch cables are designed for this purpose.
Is the cable suitable for outdoor use?
For outdoor, conduit or building-to-building connections, an outdoor fibre-optic cable specifically designed for this purpose should be used.
