Confused by Fiber Cable Types?

A friend has told me that she had some trouble in selecting the fiber cable recently. Maybe there are many people like her that are confused by fiber cable types. If you happen to be the one, you can find answer in this article. Since you are just lost in the types, let’s just skip the definition of it. (You can find this part in my previous post—Big Secret in Fiber Cable Types. It will be analyzed in two major issues, and that is fiber core and connector.

Different Fiber Cable Types Based on Fiber Cores

OM1 cable are typically wrapped by an orange jacket and has a core size of 62.5 micrometers (µm). It can support 10 Gigabit Ethernet at lengths up 33 meters. It is most commonly used for 100 Megabit Ethernet applications.

OM2 also has a suggested jacket color of orange. Its core size is 50µm instead of 62.5µm. It supports 10 Gigabit Ethernet at lengths up to 82 meters but is more commonly used for 1 Gigabit Ethernet applications.

OM3 has a suggested jacket color of aqua. It has a core size of 50µm, same with OM2, but the cable is optimized for laser based equipment that requires fewer modes of light. As a consequence of this optimization, it is capable of running 10 Gigabit Ethernet at lengths up to 300 meters. Since its inception, production techniques have improved the overall capabilities of OM3 to enable its use with 40 Gigabit and 100 Gigabit Ethernet up to 100 meters. 10 Gigabit Ethernet is its most common use.

OM4 also has a suggested jacket color of aqua. It is a further improvement to OM3. It too uses a 50µm core but it supports 10 Gigabit Ethernet at lengths up 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters.

All these are multi-mode fiber. As it is typically cost effective for inside buildings or corporate campuses, I strongly recommend it regarding the fact that some of you, like my friend, want it for private use and are on a limited budget.

Different Fiber Cable Types Based on Connectors

Fiber patch cables can be categorized into many types according to cable connectors. If the connectors attached to the two ends of the cable are the same one, this cable named same-connector type fiber patch cord. Otherwise, it is hybrid fiber patch cord which has different connectors on each end, like fiber patch cord LC to SC. Next, I will take the examples of LC-LC fiber patch cable, SC-SC fiber patch cable and LC-SC fiber patch cable.

LC-LC Fiber Patch Cable

LC to LC fiber optic cables, as one kind of fiber optic patch cables, possesses lots of advantages such as low insertion loss and back reflection loss, good durability, high temperature stability, good interchangeability and duplication. Thus they are widely used in Gigabit Ethernet and fiber channel, multimedia, telecommunication, and high speed data transmission throughout the network, etc.

SC-SC Fiber Patch Cable

Two SC fiber connectors terminated at the ends of the cable offer excellent packing density, and its push-pull design reduces the chance of fiber end face contact damage during connection. However, these big SC connectors may add to the size of the whole patch cable.

LC-SC Fiber Patch Cable

LC-SC fiber cables are available in single mode and multimode types, in simplex and duplex versions. LC connector has a low insertion loss, and a relatively small size. And LC is suitable for densely populated racks/panels. SC is ideally suited for datacoms and telecoms applications. This cable boasts the advantages of LC and SC connectors.

Conclusion

Apart from what is mentioned above, there are many fiber cable types I haven’t put forward due to the limited lime. If you have different purposes and different requirements, you can turn to FS.COM. Experts will be there answering your puzzles and offering you best service.
