Optical fiber
6/16/15  |  Technical Article  |  FiberOnSale.com

Fiber is a core refractive index higher than that of the cladding of the coaxial cylindrical dielectric waveguide. The main component of the core material is doped silica or plastic.

What is Dispersion
6/15/15  |  Technical Article  |  FiberOnSale.com

Dispersion is due to light waves in different frequency components at different transmission speeds to produce a physical effect of different time delays. Digital transmission, dispersion caused by the optical pulse broadening, resulting in around pulse overlap, causing ISI mathematics signals, resulting in increased error rate; for analog transmission, it will limit the bandwidth, harmonic distortion, making SNR system decreases. Dispersion including material dispersion, waveguide dispersion, mode dispersion, polarization mode dispersion, and other.

Optical fiber communication band
6/9/15  |  Technical Article  |  FiberOnSale.com

Optical fiber communication wavelength range: 0.8μm ~ 1.7μm (frequency 1.76 * (10 ^ 14) to 4.75 * (10 ^ 14))

Optical Fiber Communication
6/7/15  |  Technical Article

Optical fiber communication: it refers to the light as an information carrier, optical fiber as the transmission medium of communication. 

The rapid growth of optical fiber communication optical module business fierce market competition
5/17/15  |  Industry News

According to the Ministry statistics, from January to June this year, the national new 1.386 million kilometers of optical cable, optical cable line total length of 18.838 million kilometers, an increase of 18.1%, 4G network to promote the rapid development of optical fiber and cable industry.

Difference between single-mode and multimode fiber
4/26/15  |  Technical Article

Single-mode fiber is only a single path, and generally used for long-distancetransmission, there are multiple propagation paths of Multimode Fiber, multimodefiber bandwidth for 50MHz~500MHz/km, single mode fiber optic bandwidth up to2000MHz/km, optical fiber wavelength 1550nm and 850nm,1310nm, etc.
