Os1 Vs Os2 Fiber Cable

Category os1 is appropriate to internal tight buffered cable construction.

Os1 vs os2 fiber cable. The multimode fiber is prefixed with om and the singlemode mode os. Os1 and os2 are cabled single mode optical fiber specifications. Indoor fibre is more tolerant of bending called b1 3. Os2 is for outdoor loose tube cable.

The easiest points to remember are os1 is for indoor tight buffered cable. 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. Cabling is is tight buffered i e. In general single mode fiber cable is categorized into os1 and os2 fiber.

Category os2 is appropriate to a loose tube or blown fiber solution where the cabling process applies no stress to the optical fiber. The attenuation of an os1 fiber cable is higher than an os2 fiber cable. Os1 is for indoor use i e. Fia s os1 and os2 are cabled optical fiber specifications.

In 2006 os2 was born. 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. Os2 is for outdoor or loose tube use i e. Loose tube not held in medium but blown or otherwise inserted into carrier.

Manufactured into solid medium. In fact there are many differences between os1 vs os2 single mode fiber. 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.
