Multimode

Differences between multimode cables and singlemode cables

To ensure you select the right cables for your planned application, you should be aware of the differences in performance and characteristics between the two cable types.

Diameter:

• Singlemode cables (OS2) have a glass core diameter of only 9 µm
• Multimode cables have a larger diameter: OM1: 62.5 µm; OM2 to OM5: 50 µm

Data transmission:

Data transmission differs depending on range and attenuation, with the smaller core of OS2 cables resulting in lower attenuation losses. For this reason, OM multimode cable, which tends to be more prone to noise over longer distances, is only used for short-distance connections.

Distances and areas of application:

• Multimode cable (OM): from 100 to 1000 m, mainly for building cabling
• Singlemode cable (OS): up to 120 km without additional equipment, therefore ideal for connecting different company locations or connecting the company to a data centre

Combined use of multimode and singlemode cables

When planning a network, it is important to check existing and additional cables for compatibility. Every room that requires an IT connection must first have a multi-fibre single-mode cable. For further connections within the building, i.e. over short distances, multimode cables are the preferred choice. However, it is not possible to splice singlemode cables and multimode cables; converters or switches would be required for this transition.

Our multimode cables

We offer a growing selection of various multimode cables in different designs. All cables are individually packaged and come with a measurement report.

Highly sought-after: our multimode cable OM4: This is an optimised 50 µm multimode fibre for transmissions from 10 Gbps to 100 Gbps.

You also have the choice between two versions (standard / adapter):

• OM4 standard patch cable (with identical connectors at both ends, available in various versions and lengths)
• OM4 adapter patch cabel (with different connectors at both ends, available in various versions and lengths)
