Structure of ADSS optical fiber cable
In the design of the cable, the internal glass optical fibers are supported with no strain, to maintain low optical loss throughout the life of the cable. The ADSS cable is jacketed to prevent moisture from degrading the fibers. The jacket also protects the polymer strength elements from the effect of solar ultraviolet light.
Using single-mode fibers and light wavelengths of either 1310 or 1530 nanometers, circuits up to 100 km long are possible without repeaters. A single cable can carry as many as 144 fibers.
Consequently, ADSS cable is up to 72 optical fibers in jelly-filled loose tube, laid up around a central non-metallic strength member. The cable is water blocked aramid yam reinforced and polyethylene sheathed. Surface printing for the cable includes sequential length marking at one-meter intervals.

Single-mode and multi-mode:
In a nutshell, OS1 fiber is a tight buffered cable designed for use in indoor applications (such as campuses or data centers) where the maximum distance is 10 km. OS2 fiber is a loose tube cable designed for use in outdoor cases (like street, underground and burial) where the maximum distance is up to 200 km. Both OS1 and OS2 fiber optic cable allow a distance of gigabit to 10G Ethernet. Besides, OS2 fiber can support 40G and 100G Ethernet.
Single Mode Fiber vs Multimode Fiber
Single mode fiber core diameter is much smaller than multimode fiber. A typical single mode cable is a core diameter of 8 to 10μm, while multimode fiber is 50 or 62.5μm. The cladding diameter of both is 125 μm.
Laser and LED are usually used as a light source. The LED light source produces more dispersed light (many modes of light), these light sources are usually used in multimode fiber jumpers (OM1 and OM2). At the same time, laser light sources (which produce light close to a single mode) are commonly used for single mode cables.
Lasers used to drive single mode fiber produce a single wavelength of light. Therefore, its modal dispersion is much smaller than multimode fiber.
