Fiber Optic Cabling

Fibre Optic Connectivity is the answer when your organization demands world-class connectivity speeds and scalability.   With Fiber Optic Cable as the backbone of your network, your organization can count on reliable, rock-solid and lightning-fast performance.

Single Mode

Single Mode cable is a single stand of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission.  Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310nm or 1550nm. Carries higher bandwidth than multimode fiber, but requires a light source with a narrow spectral width. Synonyms mono-mode optical fiber, single-mode fiber, single-mode optical waveguide, uni-mode fiber.

Single-mode fiber gives you a higher transmission rate and up to 50 times more distance than multimode, but it also costs more. Single-mode fiber has a much smaller core than multimode. The small core and single light-wave virtually eliminate any distortion that could result from overlapping light pulses, providing the least signal attenuation and the highest transmission speeds of any fiber cable type.

What is Signal Attenuation?

Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances.

Multi-Mode

Multimode cable is made of of glass fibers, with a common diameters in the 50-to-100 micron range for the light carry component (the most common size is 62.5).  POF is a newer plastic-based cable which promises performance similar to glass cable on very short runs, but at a lower cost.

Multimode fiber gives you high bandwidth at high speeds over medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable’s core typically 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet [914.4 ml), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission.

Fibre Optic Connectors

When selecting fiber optic connectors, you need to understand how your choice will effect the performance of the solution you are developing.  Fiber optic signal quality will be affected by selecting the right connector and installing it properly so as to minimize insertion loss. CityPro can help guide you toward the  most effective option for your needs.

(In telecommunications, insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in decibels (dB).)

OTDR Testing

OTDR stands for Optical Time Domain Reflectometer. 

OTDR testing is essential to trace and repair sections of underperforming sections of fibre optic cable.  it does this by reading the levels and reflective light in the cable.  Doing so helps to locate defects in the cable that are causing attenuation.

CityPro can detect and repair any performance issue on your fibre optic network.
