Fibre Cable Types

There are quite a few different fibre cable types on the market, so which one do you need? Which fibre cable type to choose depends upon how long the cable run will be, and what the cable is going to be used for.

• Singlemode Fibre Cables
• Multimode Fibre Cables

Singlemode Fibre Cables

Singlemode fibre-optic cables can carry signals faster over greater distances due to their lower attenuation, making them ideal for long distance, higher bandwidth runs in telecoms, CATV, and campus fibre backbones between buildings in colleges and universities.

Fibre Type	Size	ISO/IEC 11801	IEC60793 Ref	Typical Run Length
Singlemode G652 D	9/125	OS1/OS2	2-50-B1.3	1000-60000m
Singlemode G657A.1	9/125	OS1/OS2	2-50-B6_a	1000-60000m
Singlemode G657A.1	9/125	OS1/OS2	2-50-B6_a	1000-60000m

Multimode Fibre Cables

Multimode fibre-optic cables have a shorter range than singlemode cables, and come in 4 distinct types (OM1, OM2, OM3, and OM4). Their shorter range usually means that they are used for within premise fibre installations between 80m and 600m in length, such as company WAN & LAN networks.

Fibre Type	Size	ISO/IEC 11801	IEC60793 Ref	Typical Run Length
N/A	62.5/125	OM1	2-10-A1a.1b	25-600m
Multimode G651.1	50/125	OM2	2-10-A1a.1	80-600m
Multimode G651.1	50/125	OM3	2-10-A1a.2	300-900m
Multimode G651.1	50/125	OM3	2-10-A1a.3	300-900m

Our range of fibre-optic cable includes both singlemode and multimode cables in central loose tube, multi loose tube, and tight buffered constructions. A range of sheath types, sheath colours, and armouring options are also available.
