Bend Sensitive and insensitive cables

How Far Can You Bend Your Fiber?

We know that stress and overstrain is a major enemy of the fiber’s lifespan, so cable installers must ensure that during the installation, fiber cables would not suffer from undesirable stretching or bending. Pulling, pushing and blowing are the three techniques used in wire management, which usually cause minor installation strains even for a seasoned installer. It is unavoidable, but…

Difference Between 50 Ohm and 75 Ohm Coaxial Cable

People know much about the coaxial cables, but they know little about the different impedance of coaxial cables, namely 50 Ohm and 75 Ohm coaxial cables. Even many optical manufacturers fail to adequately explain the difference between the two types of coax and why they need one type over the other. Therefore, today’s article will define some of the most…

C3KX-NM-10G Network Module Overview

Questions like whether a 1G SFP can be used on the SFP+ port of the switch and support 10G data rate are frequently asked by overall users. Generally, you will get the answer “no”. Because Most (95+%) SFPs and SFP+s will only run at the rated speed, no more, no less. Even though SFP and SFP+ have the same port…

Male-Female and Female-Female Fixed Fiber optic Attenuators

Introduction to Fiber Optic Attenuator

Fiber optic attenuators are often used to control the optical signal strength in fiber optic links. For example, in a DWDM based system, the DWDM employs multiple wavelengths and channels in different communication protocols and bit rates requiring precise tuning of the power levels of the channel signals. Fiber optic attenuators are often used to adjust the optical power signal…
