Typically speaking the maximum attenuation of os1 is 1 0db km for 1310nm and 1550nm while the numerical value of os2 is 0 4db km for 1310nm and 1550nm.
Os1 vs os2 fiber cable.
Cabling is is tight buffered i e.
Os1 fiber optic cable is designed for premises where the maximum distance is 2 000 metres with transmission speeds of 1 to 10 gigabit ethernet.
Os1 is for indoor use i e.
The multimode fiber is prefixed with om and the singlemode mode os.
It was written around the premise that the low water peak wavelengths around 1383 nanometers was required to have an attenuation of less than 0 4db over 1 kilometre for use in cwdm.
Fibre cable referred to as os1 had its inception in 2002 and was written around the 2 glasses available at the time being g652a and g652b.
Manufactured into solid medium.
Category os1 is appropriate to internal tight buffered cable construction.
Indoor fibre is more tolerant of bending called b1 3.
The attenuation of an os1 fiber cable is higher than an os2 fiber cable.
Om1 om2 om3 om4 om5 and os1 os2 fiber in ansi tia 568 3 d the tia adopted the nomenclature for fiber found in the international standard iso iec 11801.
Fia s os1 and os2 are cabled optical fiber specifications.
Os1 type cable is predominantly of a tight buffered construction whereas os2 is a loose tube or blown cable construction where the cable designs applies less stress on the optical fibers.
Os2 is for outdoor loose tube cable.
In 2006 os2 was born.
Os2 is for outdoor or loose tube use i e.
Loose tube not held in medium but blown or otherwise inserted into carrier.
The easiest points to remember are os1 is for indoor tight buffered cable.
Category os2 is appropriate to a loose tube or blown fiber solution where the cabling process applies no stress to the optical fiber.
