Fiber optic cable distance chart.

Light will propagate through the cladding layer but poorly. Om1 cable will support 1000base sx out to 275 meters and that distance jumps to 550 meters with om2 cable. Speed gbps maximum distance meters by optical media type. A multimode fiber has a large core thus allowing many light rays modes.

Optical glass fiber basics. Multimode and single mode optical fiber cables are two different cable types in optical networking. 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. Typically the multimode fiber optic cable speed and the transmitting distance limits are 100 mbit s for distance up to 2 km 100base fx gbit s up to 1000m and 10 gbit s up to 550 m.

Using a larger core size multimode fiber cable allows multiple light signals to be transmitted in a single fiber over short distances. The following chart lists the transmission distance of smf and mmf at different fiber optic cable speeds. Os2 fiber optic cable is designed for larger transmission distances in the range of 5 000 to 10 000 metres with similar transmission speed of 1 to 10 gigabit ethernet. An optical fiber is comprised of two inseparable sections a core and it s cladding.

Light propagates through the core section and the cladding provides an internal reflection boundary. In table 3 attenuation specifications of os1 and os2 fiber optic cables as mentioned in iso iec and en standards are summarized. 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. Fabric is already locked.

As you can see from the chart below different fiber core types have vastly different limitations for speed and maximum distance. Maximum distances using fiber cable types om1 om2 om3 om4 os1. Fiber optics color standards. The standards for multimode cables are as follows.

Comparison between different types of os. Unless the cable is being lain long distance for a telecom company distance limits should never be an issue for single mode fiber. Fiber optic cables are available in a wide range that varies according to use length diameter etc. Om1 multimode fiber optic 300 meters om1 is the basic version of multi mode cable being able to maintain 1gb data speeds for up to 300 meters.
