Fibre Channel Cable Length Limits

Millions of fibre channel links are installed each year and most are less than 100 meters long.

Fibre channel cable length limits. Fibre channel links may span over 10 kilometers at billions of bits per second or gigabits second gb s. Short answer is it depends but usually yes. The length of cable will be impacted. A quick search of the standards shows os1 fiber is good to 2 km while os2 is good to 10 km.

It should be noted that cat7 cable has harsher distance limits than cat5e cat6 and cat6a. Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable. Delay will be met by keeping the total channel length less than or equal to 100m. The 10 km maximum for a fibre channel connection assumes the use of single mode fiber which is usually only used for long runs such as to a remote mirror site.

Cable manufacturers specify the highest frequency at which their cables will carry a signal of acceptable quality for one kilometer mhz km. This specification is called modal bandwidth. The fibre channel industry association has developed the fibre channel roadmap to. Om1 has been the most popular multimode fiber choice throughout the 80 s 90 s and into the early 2000 s and was the most common multimode fiber used and yet it has the lowest data carrying capacity and shortest distance limitations as compared with other multimode fiber types.

Ethernet 100 meters 328 feet there are a few different versions of ethernet cable but they all have a maximum distance of 100 meters 328 feet. The length of a fibre optic cable run is primarily determined by whether a strong enough laser signal is received by the gigabit transceiver commonly known as an sfp1 although there are other considerations such as modal dispersion and signal integrity for signal propagation lets. For information on audio video cable distance limits click here. This is the maximum length you can have for each type of cable without using something such as a hub to continue the signal.

And you probably should long answer follows. Insertion loss can be met by substituting the proper length of patch cable for the horizontal cable. Om3 and om4 came after the 1000base sx standard was written so the distances up to 860 meters listed in the chart below are based on the gigabit fibre channel values.
