In a fiber optic system, connectors and optical devices on the output of the transmitter may cause reflection, absorption, or scattering of the optical signal. These effects may cause light energy to be reflected back at the source and interfere with source operation. In order to reduce the effects of interference, you may need an optical […]

Differences between FBT and PLC Splitter
With the growing demand for optic signal transmission, fiber optic splitter becomes more and more important in today’s fiber optic communication. In terms of principle, optical cable splitter can be divided into FBT (Fused Biconical Taper) splitter and PLC (Planar Lightwave Circuit) splitter. Since, these two splitters have different working principles and applications, this post will make a […]
Things You Should Know about Optical Attenuator
We always utilize an amplifier to improve signal electricity in fiber optic transmission. But what if there is too much light deliver through a fiber optic receiver? At that time, you may need an optical attenuator to reduce the power level. This post will help you get better understanding of optical attenuator. An optical attenuator, or […]
An Introduction of CWDM Fiber Optic Splice Tray
When we talk about CWDM Tray, it means the CWDM splcie tray but not the rack mount “CWDM Tray”. A CWDM splice tray is a fiber optic splice tray that can be integrated with CWDM components (e.g. CWDM MUX). The CWDM tray allows for easy integration in enclosures, wall-mount boxes, or Optical Distribution Frames (ODFs). […]
Optical Multiplexing for High Speed Communication Systems
Introduction Optical transmission uses pulses of light to transmit information from one place to another through an optical fiber. The light is converted to electromagnetic carrier wave, which is modulated to carry information as the light propagates from one end to another. The development of optical fiber has revolutionized the telecommunications industry. Optical fiber has […]
Wavelength Selective Couplers and Splitters
Wavelength Selective Couplers (or Splitters) are used to either combine or split light of different wavelengths with minimal loss. Light of two different wavelengths on different input fibers can be merged (combined) onto the same output fiber. In the reverse direction light of two different wavelengths on the same fiber can be split so that […]
