How Should I Terminate My Fiber Optic Cable

In today’s day and age, we are more connected than ever. And we expect it.   At the work place we are attending virtual trainings on the latest technologies and we are connecting across the globe with our colleagues in real-time meetings – with just the click of a button.   When we leave work, we are going home using app-based scooters and bicycles that only needs the swipe of a cell phone. And if taking a highway home, you no longer search for change at a toll booth but instead you drive through a toll lane that scans and charges your account as you drive underneath it.   And it doesn’t stop at home. We are answering emails, while streaming Ultra HD video on our smart TV’s, all while having the latest super hero flick downloading on our tablet to watch on an upcoming business trip.   With the ever-increasing demand for the bandwidth needed to meet today’s expectations; how we design, install, and maintain our fiber optic networks must evolve with th...

Understanding Fiber Optic Based Light Source

by www.fiber-mart.com Each piece of active electronics will have a variety of light sources used to transmit over the various types of fiber. The distance and bandwidth will vary with light source and quality of fiber. In most networks, fiber is used for uplink/backbone operations and connecting various buildings together on a campus. The speed and distance are a function of the core, modal bandwidth, grade of fiber and the light source, all discussed previously. Light sources of the fiber light source are offered in a variety of types. Basically there are two types of semiconductor light sources available for fiber optic communication – The LED sources and the laser sources.   Using  single mode fiber  for short distances can cause the receiver to be overwhelmed and an inline attenuator may be needed to introduce attenuation into the channel. With Gigabit to the desktop becoming commonplace, 10Gb/s backbones have also become more common. The SR interfaces are also...

Knowledge About GPON SFP Transceivers

by Fiber-MART.COM GPON stands for Gigabit Passive Optical Network. GPON is one of the key technologies that are being used in fiber-based (FTTx) access networks, including fiber to the home (FTTH), fiber to the business (FTTB), fiber to the curb (FTTC), etc. GPON system contains two main active transmission components, namely optical line termination (OLT) and optical network termination (ONT) or optical network unit (ONU). Modern OLT and ONT/ONU use compact fiber optic modules to achieve the triple-play GPON services. These modules are known as GPON SFP transceivers. This post will give a comprehensive introduction to GPON SFP modules.   What Is GPON SFP? GPON SFP is one type of gigabit optical transceivers that are used in GPON system, which is compliant with ITU-T G.984.2 standard. It is a bidirectional module that has SC receptacle and works over simplex single-mode fiber optic cable. A GPON SFP module transmits and receives signals of different wavelengths between the...

How Does Fiber Identifier Work In Your Fiber Optic Network

by Fiber-MART.COM Fiber Optical Identifier  is an essential installation and maintenance instrument which can identify the optical fiber by detecting the optical signals transmitted through the cables, during this process the fiber optic identifier do no harm or damage to the fiber cable and it also don’t need opening the fiber at the splice point for identification or interrupting the service.During fiber optic network installation, maintenance, or restoration, it is also often necessary to identify a specific fiber without disrupting live service.   The Fiber optic identifier have a slot on the top. The fiber under test is inserted into the slot, then the fiber identifier performs a macro-bend on the fiber. The macro-bend makes some light leak out from the fiber and the optical sensor detects it. The detector can detect both the presence of the light and the direction of light.   A fiber optic identifier can detect “no signal”, “tone” or “traffic” and it also...

Optical Power Meter – an Essential Tester for Fiber Optic Testing

by Fiber-MART.COM In  fiber optic network , whether installing new cable, or troubleshooting existing cable, cable testing always plays an important role in the process. Optical power meter which is widely used for power measurement and loss testing is well known to us. Today, we are going to talk about this familiar and essential fiber optic tester—optical power meter, in details.   As its name suggests, optical power meter is a meter which is used for testing optical power. So, what is optical power? And how to measure power by using optical power meter?   Optical Power In simple terms, optical power is the brightness or “intensity” of light. In optical networking, optical power is measured in “dBm” which refers to a decibel relative to 1 milliwatt (mW) of power. Thus a source with a power level of 0 dBm has a power of 1 mW. Likewise, 3 dBm is 2 mW and -3 dBm is 0.5 mW, etc. And one more thing should be known is that 0 mW is negative infinity dBm.   ...

WHY IT PROFESSIONALS PREFER FIBER OPTICS

More and more IT professionals are choosing to install fiber optic cables over the copper cables that have traditionally been used to create networks. Why is that? Well, for one, fiber optic cables have proven to transmit data substantially faster than copper cables. Fiber optic cables use light to move data around, and that makes them quicker. But that’s not the only reason why IT professionals are choosing fiber optic cables. Here are several other reasons.   FIBER OPTIC CABLES DON’T LOSE THEIR SIGNAL STRENGTH AS QUICKLY AS COPPER CABLES. When copper cables are forced to transmit data over a long distance, they end up losing a lot of their signal strength. IT professionals refer to this as low attenuation, and it can obviously be problematic for companies that need cables capable of carrying data over longer distances. Data doesn’t break down in fiber optic cables like it does in copper cables, which, outside of speed, is one of the biggest benefits of using them.  ...

QSFP+ to 4xSFP+ AOC and QSFP+ MTP Breakout Cable Solution

Migration from 10G to 40G is an inevitable trend in data center. Migration means you need new QSFP+ transceiver modules, fiber patch cables and other equipment. Common two methods to migrate from 10G to 40G for short distance are QSFP+ to 4xSFP+ AOC and QSFP+ MTP breakout cable solution. When you come across this issue, it’s hard to tell which one is better. This article will introduce their difference and tell you how to make the right decision. 40G QSFP+ to 4xSFP+ AOC (active optical cable) is composed of a QSFP+ connector on one side and four individual SFP+ connectors on the other side. The QSFP+ connector (40Gbps rate) offers four parallel, bidirectional channels and each operates at up to 10.3125 Gbps. The QSFP+ connector can be installed into QSFP+ port on the switch and feed up to four 10G SFP+ links. And the link lengths can reach 100 meters on OM3 fiber. It’s a cost-effective interconnect solution for 40G and 10G switches and servers. QSFP+ MTP Breakout Cable The o...

Introduction to Simplex, Half Duplex and Full Duplex

图片
Introduction to Simplex, Half Duplex and Full Duplex by Fiber-MART.COM Simplex, half duplex and full duplex are three kinds of communication channels in telecommunications and computer networking. These communication channels provide pathways to convey information. A communication channel can be either a physical transmission medium or a logical connection over a multiplexed medium. The physical transmission medium refers to the material substance that can propagate energy waves, such as wires in data communication. And the logical connection usually refers to the circuit switched connection or packet-mode virtual circuit connection, such as a radio channel. Thanks to the help of communication channels, information can be transmitted without obstruction. A brief introduction about three communication channel types will be given in this article. Three Types of Communication Channel 1) Simplex A simplex communication channel only sends information in one direction. For exa...
