Os1 single mode fibers are compliant with itu-t g. 652a or itu-t g. 652b standards. Except, the low-water-pinnacle fibers defined with the resource of itu-t g. 652c and g. 652d moreover come under os1 single mode fibers. That is to mention, os1 is compliant with specs of itu-t g. 652. But, os2 unmarried mode fibers are most effective compliant with itu-t g. 652c or itu-t g. 652d standards, which approach os2 is explicitly carried out to the low-water-top fibers. Those low-water-top fibers are typically used for cwdm (coarse wavelength branch multiplexing) programs.
Except the requirements, the principle distinction among os1 and os2 single mode fiber is the cable creation. Commonly, os1 cabling is tight-buffered creation, it really is normally used for indoor applications, which incorporates campus or records middle. But os2 cabling is unfastened-tube layout. Cable with this creation is appropriate for outdoor times like avenue, underground and burial. Because of this, os1 indoor fiber has more loss constant with kilometer than os2 outdoor fiber. In wellknown, the maximum attenuation for os1 is 1. zero db/km and for os2 is zero. 4db/km. As a result, the maximum transmission distance of os1 single mode fiber is km however the most transmission distance of os2 single mode fiber can achieve five km and is up to ten km. Then for a lot of these motives, os1 is lots less expensive than os2. There can be factor need to be aware of is that each os1 and os2 single mode fibers over their distance will permit speeds of 1 to 10 gigabit ethernet. All of those versions amongst os1 and os2 referred to above are indexed within the table underneath. You can get a easy know-how from it.
