Structured cabling: Choose a copper, fiber, or coaxial structured cabling system for a variety of media applications. These can connect your CCTV cameras to monitors and recording devices, power your access control system, and link your commercial audio components together. A wired infrastructure is a good solution if you needed guaranteed coverage and dependability.
Wireless connectivity: When wiring isn’t a feasible option, clear up the cables with wireless connectivity. Low voltage devices can communicate wirelessly in a number of ways, including over radio frequencies, via microwaves, and with infrared laser technology. A wireless site survey can help determine your eligibility for this type of infrastructure.
What is Fiber Optic Cable?
A fiber optic cable is a network cable that contains strands of glass fibers inside an insulated casing. They’re designed for long-distance, high-performance data networking, and telecommunications. Compared to wired cables, fiber optic cables provide higher bandwidth and transmit data over longer distances. Fiber optic cables support much of the world’s internet, cable television, and telephone systems.
There are two types of fiber optics
Single Mode Fiber: (SMF) is an optical fiber designed to carry only a single mode of light – the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining Maxwell’s equations and the boundary conditions. For single-mode fiber optic cable speed, no matter data rate is at 100 Mbit/s or Gbit/s, the transmission distance can reach up to 5 km. In that case, it is usually used for long-distance signal transmission.
Multi-Mode: Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 100 Gbit/s.
Plastic optical fiber (POF) or polymer optical fiber is an optical fiber that is made out of polymer. Similar to glass optical fiber, POF transmits light (for illumination or data) through the core of the fiber. Its chief advantage over the glass product, another aspect being equal, is its robustness under bending and stretching.
Multimode vs. Single-Mode Fiber Distance
Multimode fiber has a much shorter maximum distance than single-mode fiber, making it a good choice for premise applications. Single-mode fiber can go as far as 40 km or more without hurting the signal, making it ideal for long-haul applications.
Multimode vs. Single-Mode Fiber Bandwidth
Single-mode fiber has a significantly higher bandwidth than multimode fiber. You can use a pair of single-mode fiber strands full-duplex for up to twice the throughput of multimode fiber cable. Single-mode cable’s lengths and speeds are attainable because sending light in a single-mode nullifies differential mode delay (DMD) which is the primary bandwidth limiting factor of multimode.
Multimode vs. Single-Mode Fiber Pricing
Multimode and single-mode cables cost about the same. But multimode fiber systems are much cheaper than single-mode fiber systems and considered more cost-effective in the right application. This is due to the lower price of multimode transceivers and components. Multimode transceivers are generally two to three times cheaper than single-mode transceivers. Also, LED components used as transmitter optics in multimode devices are cheaper to purchase and calibrate.
