Tunable DWDM Lasers - a short overview

by www.fiber-mart.com A tunable laser is a laser whose wavelength of operation can be altered in a controlled manner. While all laser gain media allow small shifts in output wavelength, only a few types of lasers allow continuous tuning over a significant wavelength range.   In order to enable high-capacity optical networks, DWDM systems which use a single optical fiber for optical signals of several different wavelengths are being utilized.Wavelength tunable optical transceivers are becoming important as components that enable ROADM -  Reconfigurable Optical Add/Drop Multiplexer - functionality in next-generation networks. These transceivers have the characteristic that their wavelengths can be switched between different DWDM channels while in use in the network. Tunable transceivers are only available in DWDM form because the CWDM grid is too wide. Typically, these tunable optics are for the C-Band 50GHz. Around 88 different channels can be set with intervals of 0.4nm, which

WHAT ARE LC-LC PATCH CABLE?

by www.fiber-mart.com LC-LC patch cord  has become an important ingredient of high-density cabling network infrastructure. To make LC-LC fiber patch run a long way, the manufacturers have already invented LC-LC patch cables with different features to meet various requirements in data centers and increase the network performance.        Kind of Fiber Patch Cable required in Data Canters? Nowadays fiber patch cord has broad adaption in applications spanning from telecommunications to data communications. Fiber patch cord has been the most suitable and prevalent bandwidth feeder. To satisfy the increasing demands for higher density, bandwidth and easier management, more and more data centers are deploying fiber patch cable of high performance. Factors like high return loss which results in low insertion loss of connectors and light loss of optical fiber used for fiber patch cable makes it the best choice. Let’s have a look at several popular LC-LC fiber patch cables trending in

How to choose the right Fiber Optic Connector?

by www.fiber-mart.com When selecting the right  fiber optic connector  to use for any job or installation there are a few key features to make note of. Not doing the proper preparation cable make the customer go from satisfied to unsatisfied pretty quickly. So what are some keys factors to look at when selecting the right connector for a fiber optic installation?   What is the equipment or panel that the fiber optic cables are connecting to? Match the class size to the appropriate connector glass type OM1 to a beige color OM1 connector OM2 50 micron black connector or aqua OM3/4 50 micron aqua or maroon connector OS2 single-mode blue connector The termination Method: Mechanical, Epoxy Style (Termination Technique) Mechanical – termination of a connector can take less than 2 minutes.  The disadvantages are the overall pull tension, but the connector can be reused.   Epoxy Style Termination: This termination technique requires a lot of time and expertise, The ad

Importance of Reestablishing Fiber Connections Effectively

by www.fiber-mart.com Fiber Optic cables  offer a business many benefits for safe, fast installations with higher bandwidth frequencies. Fiber optic cables provide extreme pull tensions up to 600 lbs and a bend radius equal to coax cables.    If loss of fiber does occur it can result in disrupted communications and negative effects to local businesses. Review the steps below in order to repair any tainted connections quickly and effectively.Making a plan of how to respond to any cable failure is a great idea. Have questions answered ahead of time such as: Do we have the proper equipment if a loss occurs? Who will have proper training and materials to fix the issue? How will we know if the issue occurs? How quickly do we want to be able to resolve any issues?   Important Factors to Restoring a proper connection effectively   1) Documentation- Producing accurate documentation during the installation process and making updates is critical. Start with manufacturer data/tech

Fiber Optic Connectors and Termination Videos

by www.fiber-mart.com Fiber Optic connectors  are definitely distinctive compared to the traditional copper cable connectors. Instead of the metal-to-metal contact, fiber optic connectors need to align microscopic glass fibers in order for the communication data to carry efficiently.    Each connector contains three key components: Ferrule, Connector Body and Coupling Mechanism.   The ferrule is the thin structure that holds the glass fiber in place and they are generally made of ceramic, metal or plastic. The connector body is what holds the ferrule in place and allows it to attach to the members within the cable fiber. A coupling mechanism which essentially holds the connector while it is linked to another device. It may contain a clip or bayonet nut depending on the connector type.    Now, let's look at some popular connectors and what they are used for within networking applications:   SC Connector-(also known as the square connector) this type of connector

Things to Know About Bend Insensitive Multimode Fiber

by www.fiber-mart.com Bend insensitive multimode fiber (BIMMF) has become a very active area within the telecommunication industry once it was introduced and popularized. It typically signifies technical advancements in the production of multimode optical fiber for easier installation, and cable management for  multimode fiber cables  through improvements in bend insensitivity. This article will focus on some useful information about BIMMF from the perspective of its working principle, performance in networking and unique advantages as well.   What Is Bend Insensitivity? An optical fiber consists of a core and a cladding. Although both of these regions are made from glass in telecommunications grade fibers, they are significantly different from each other. Each region is designed to capture light within the core and transmit it to the opposite end of the fiber. During this process, the light may follow many paths, depending on the angle at which the light hits the boundary, i

MPO Cabling high-density and high-port count fiber equipment

by www.fiber-mart.com As networking equipment becomes denser and port counts in the data center increase to several hundred ports, managing cables that are connected to these devices becomes a difficult challenge. Traditionally, conneting cables directly to individual ports on low-port-count equipment was considered manageable. Applying the same principle to high-density and high-port-count equipment makes the task more tedious, and it is nearly impossible to add or remove cables that are connected directly to the equipment ports.   Using fiber cable assemblies that have a single connector at one end of the cable and multipe duplex breakout cables at the other end is an alternative to alleviate cable management. Multifiber Push-On (MPO) cable assemblies can achieve these goals. The idea is to pre-connect the high-density and high-port-count Lucent Connector(LC) equipment with and MPO to LC Breakout cable (shown in Figure 6-1) to dedicated MPO modules with a dedicated patch pane

Things to Know About Fiber Optic Media Converter

by www.fiber-mart.com With the expected growth of today’s communications, network operators must meet the continuing growth in data traffic and the increasing demand for bandwidth while making full use of the investment in the existing network infrastructure. Instead of costly upgrade and rewiring for fibers, fiber media converters provide a cost-effective solution by extending the life of the existing structured cabling. How fiber optic media converter can achieve this? And how much do you know about it? Today, this article will tell you something about fiber media converter.   What Is a  Fiber Optic Media Converter ? Fiber media converter is a simple network device that can connect two different media types such as twisted pair with fiber optic cabling. Its function is to convert the electrical signal used in copper unshielded twisted pair (UTP) network cabling into light waves that used in fiber optic cabling. And fiber media converter can extend transmission distance over
