How To Choose Fiber Patch Cord?

FAQ 1. What is fiber optic?

Fiber optic technology refers to the process of transmitting light down the thin glass (sometimes plastic) strands. Fiber optic cables transfer the information from one end to another. One end of the fiber connects to LED or laser that sends information; the other end is connected to a device designed to recognize the incoming light. Most often used in communication, medicine, aeronautics, or broadcasting, fiber optics.

FAQ 2. What is multimode?

Multimode fibre allows light to travel down multiple paths and has a large diameter, typically 50-100 microns. Over medium distances, multimode fibers give high bandwidths at high speeds. Light waves are dispersed into numerous paths, or modes, as they travel through the cable’s core typically 850 or 1300nm. In cable runs longer than 914,4 meters, the multiple cable pats can cause distortion at the receiving end, resulting in an unclear and partial data transmission. Multimode cables are considered to be the “domestic” fiber as they are used for local-area network, as an example, they can be used in FTTH. Multimode can reach up to 100Gbps Ethernet.

FAQ 3. What is single mode?

Single mode cables are designed to carry light directly down the fiber. It is a single strand of glass fiber and has a diameter of 8.5-10 microns. Because it has one mode of transmission, it will propagate 1310 or 1550 nm. Compared to the multimode fiber, the single mode patch cords carry a higher bandwidth, but it requires a light source with a narrow spectral width. The single mode gives a higher transmission and up to 50 times more distance than multimode. The core from a single mode cable is smaller than one from a multimode. Single mode is a vital part of broadband networks. It was designed to transmit data over long distances, thus making it perfect for cable television networks or college campuses.

FAQ 4. Simplex and Duplex cables – What is the difference between them?

Simplex cables consist of a single strand of glass fiber and is widely used when a single transmit/receive line is required between devices. Duplex cables consist of two strands of glass fiber and are used in situations where separate transmit and receive lines are required.

FAQ 5. Do single mode connectors work on multimode cables?

True, you can use single mode connectors on multimode, but not the other way around.

FAQ 6. What can OM5 do to cover my bandwidth needs?

OM5 cabling was designed to benefit the data centre and to meet the bandwidth challenges. OM5 fiber is optimized for short division multiplexing and supports at least four wavelengths in the 850-950nm range.

It enables optimal support of merging SWDM (Shortwave Wavelength Division Multiplexing) applications that reduce parallel fiber count by at least a factor of four, to allow continued use of just two fibers for transmitting 40 Gb/s and 100 Gb/s and reduced fiber counts for higher speeds.

FAQ 7. Why does multimode cost more than single mode?

It’s all about manufacturing costs. The multimode fiber has a graded-index core with tight performance requirements that implies more costs, compared to the single mode fiber which has a step-index core.

FAQ 8. What types of fiber optic connectors are available on the market?

The common types of fiber optic connectors are ST, SC, FC/PC, FC/APC, and LC. The most popular connector is LC due to its high performance, small size, and ease of use.

FAQ 9. How many lengths of Fiber can support?

1M, 1.5M, 2M, 3m, 4m, 5m ... 100m, or customized.

FAQ 10. What are brands of Fiber Cable?

Brands: Corning Fiberhome, YOFC，or other brands are available.

FAQ 11. What is the brand of Ferrule?

Brand: CCTC
