OS1 vs. OS2 Single-mode Fiber Cable


Single-mode fiber (SMF) cables help superior community programs required in facts facilities, permitting guaranteed basic overall performance for Gigabit applications. SMF may be categorised into OS1 and OS2. That is, OS1 and OS2 are cabled SMF specs. For many humans, one of the confusing components in fiber optics industry might also moreover contribute to the standardization, because numerous requirements may be sure under one fiber cable kind, simply as SMF. Actually, the variations among OS1 and OS2 specs are a bit apparent. This textual content will provide an explanation for the versions among OS1 and OS2.
The table listed below is prepared OS1 and OS2 specification variations.


OS1 vs. OS2 – Standards
First introduced inside the year 2002, OS1 refers to a totally vintage specification for SMF. The mechanical, optical and environmental traits of OS1 are compliant with ITU-T G.652A or ITU-T G.652B (IEC 60793-2-50 Type B1.1). Additionally, the low water peak fibers categorized in ITU-T suggestions as G.652C and G.652D additionally come underneath OS1 fibers. To placed it honestly, OS1 is a elegant term used to specify SMF that comes under the ITU-T G.652. Or in any other way, OS1 covers all the SMFs that take a look at ITU-T G.652 developments. In evaluation, OS2 have become introduced inside the yr 2006. Only G.652C and G.652D come underneath OS2, which means that OS2 SMFs are low water peak fibers only.
OS1 vs. OS2 – Cable Construction and Application
OS1 is tight-buffered cable production, appropriate for indoor packages, which include campus or information facilities. On the opposite, OS2 is free-tube cable production, suitable for outdoor programs, which includes avenue or underground.
OS1 vs. OS2 – Fiber Optical Performance
OS1 or OS2 fiber optical overall performance is stated mainly from their attenuation and transmission distance. As for OS1 going for walks among 1310 nm and 1550 nm, its maximum attenuation allowed constant with km for an set up cable is 1.Zero db, with the most transmission distance reaching 2 km at 10 Gigabit Ethernet (GbE) transmission. When concerning about OS2, maximum attenuation allowed in step with kilometer is zero.4db between 1310 nm and 1550 nm, allowing the maximum transmission distance of 10 km at 10GbE. As an extended way as 40GbE transmission is worried, the maximum distance of SMF is forty km. For example, QSFP-40G-ER4, a Cisco 40GBASE-ER4 transceiver, takes SMF as its transmission medium for 40G links. The image beneath shows this Cisco QSFP-40G-ER4 module indexed on Fiberstore.


Quick Notes
OS2 SMFs can’t be linked with OS1 SMFs. If they're connected, surprising sign overall performance at water top place ought to arise. So, it you need to use SMFs for your indoor programs, then choose OS1. For outside cases, OS2 is optimized. Besides, while the required transmission distance is less than 2 km, it’s clever to select OS1 SMF, on the grounds that OS1 is able to meet this requirement whilst costing less than OS2 SMF.
Conclusion
According to what had been mentioned above, the confusion amongst the ones OS1 and OS2 specs has been cleared off. 10Gtekstore offers various fiber optical merchandise, which include the ones OS1 and OS2 SMFs of immoderate notable. In addition, Fiberstore moreover materials fiber optic transceivers which might be definitely compatible with some essential manufacturers, which include Brocade QSFP+. You can visit 10Gtekstore for extra data about OS1 and OS2 SMFs similarly to the associated fiber optic transceivers.
