We can categorize SMF cable into OS1 fiber optic cable and OS2 fiber optic cable. We cannot connect OS2 single-mode fiber cables with OS1 single-mode fiber cables, leading to lousy signal performance. That's why it's significant to understand the diversity between OS2 and OS1 fiber cables.
Differences between OS1 and OS2 Single Mode Fiber Cables:
Standard:
OS1 single-mode fiber cables are adaptable to ITU-T G.652, incorporating ITU-T G.652B and ITU-T G.652A standards, ITU-T G.652C, and ITU-T G.652D standards. Nevertheless, OS2 SMF cables are only adaptable to ITU-T G.652D and ITU-T G.652C standards that we specifically apply to LWP (low-water-peak) fibers. We usually use these LWP fibers for CWDM implementations. There is the declaration of a modern standard G.657.A1 for bending-insensitive fiber cables for cost balance and optimized performance. Some OS2 SMF optical fiber cables deal with that standard.
Cable Construction:
OS1 fiber cable embedded in a massive polymer jacket is appropriate for constructing tight-buffered wires of indoor implementations. We generally enclose the jacketed fiber with a collection of adaptable fibrous polymers strength members such as aramid within a thin plastic covering to create a simple fiber cable for indoor deployments. However, OS2 fiber optic cable is primarily related to loose-tube fiber construction, and it is more suitable for outdoor situations. We require a considerably more strong cable construction when utilizing some problematic conditions. We place helically OS2 singlemode fiber cables into rigid tubes enabling the wire to extend without extending the fiber to save the optical fiber from stress.
Attenuation:
OS1 cable’s attenuation is more than an OS2 cable. Generally speaking, OS1’s highest attenuation is 1.0db/kilometer for 1310 nanometers and 1550 nanometers, whereas OS2’s numerical value is 0.4db/kilometer for 1310 nanometers and 1550 nanometers. Accordingly, the highest transmission range of OS1 is 10 kilometers, whereas the highest transmission range of OS2 can extend to 200 kilometers. Both OS1 SMF and OS2 SMF will support speeds of 1GbE to 10 Gigabit Ethernet with different transmission ranges. Moreover, we can apply the OS2 SMF cable for 40 Gigabit/100 Gigabit Ethernet links.
The specification chart below will clearly show the dissimilarities between OS1 SMF and OS2 SMF cables.
How to Choose between OS1 and OS2 Single Mode Fiber Cables?
Concerning the cable selection between OS1 SMF and OS2 SMF, it is significant to understand that we support these cables for incessant transmissions. Select the correct wires which have a foundation for your connection length requirements.
We apply OS1 fiber optic cables for indoor infrastructures of a network, which we primarily deploy in networks of internal campus and internal wiring within data centers and telecommunication exchanges. OS2 wires are perfect for universal and indoor loose tube problems, including backhaul networks and external plants. Moreover, OS1 fiber cables suit your interior application requirements; when we need them for outside network substructure, then OS2 will be the right choice.
Why Choose OS2 Fiber Instead of OS1 Fiber?
Subsequently, comparing the OS1 and OS2 fiber optic cable, we can conclude that the OS2 wire is better for long-distance transmission by giving an outstanding performance with minor losses. Why not select the best OS2 wires to show good presentation for these days' excessive speed data systems?
OS1 was the only standard for SMF with the highest connection length for building cabling, about 10 kilometers, which can no longer fulfill people's growing requirements for longer connection lengths. The OS2 SMF cables are best for joining 1G, 10G, and 100G Ethernet links, meeting the demands of extraordinary performance with extensive ranges. Consequently, most vendors tend to offer solutions with OS2 fiber optic cables for new network applications.
