Overview of GPON Fiber Network Architecture
Passive optical networks (PON) technology was available in the middle of 90s, is the highest speed, longest life, lowest cost network infrastructure available in the market, offering a genuine future‐proof access network with flexibility and upgrade capability well into the future. Since the huge development of network, various standards have been established and matured. PON developed from the first ATM PON (APON) and then evolved... -
Fiber Optic Pigtail: Types and How to Splice It?
In fiber optic cable installation, how cables are attached to the system is vital to the success of network. If done properly, optical signals would pass through the link with low attenuation and little return loss. What is Fiber Optic Pigtail? A fiber pigtail is a single, short, usually tight-buffered fiber optic cable with a factory-installed connector on one end, and un-terminated fiber on... -
Simplex vs Duplex Fiber Optic Cables
Simplex vs duplex fiber optic cables what are they different? It is known to all that fiber optic cable is made of glass or plastic that mainly used for transmitting information. Fiber optic cable can be divided into many types according to different classification principles, such as source, mode, usages etc. Different kinds of fiber optic patch cables have different applications. This paper will focus on... -
Twisted Pair Cables Cabling for Ethernet Network
Twisted pair copper cabling is the most ubiquitous for Ethernet network and telephone installations. But how much do you know about twisted pair cable? What makes it different from other cables and how many types of twisted cables are there? What is Twisted Pair Cables? Twisted pair cabling consists of two conductors of a single circuit, twisted together. By twisting the wires, some part... -
Optical Amplifier is a Key Technology for Restoring Signals
Introduction To Optical Amplifiers Optical amplifiers, as the key technology for optical communication networks, have made it possible to transmit many terabits of data over distances from a few hundred kilometers and up to transoceanic distances with wavelength-division multiplexing (WDM) technology, which allows the transmission of multiple channels over the same fiber. The transmission distance of any optical fiber communication system is eventually limited by... -
Why Not Use Raman Amplifier to Extend the CWDM Network Reach?
In comparison with the long-haul DWDM network that uses the thermo-electric coolers to stabilize the laser emissions essential, CWDM technology employs wider wavelength spacing and less expensive components, allowing the wavelength fluctuation of uncooled directly modulated laser diodes (DMLs). But on the other hand, the CWDM network exists the limitation for the uncooled DMLs’ output power and the additional loss of CWDM Mux Demux... -
Quick View about Armored Fiber Cable
Tired of broken fiber optic patch cords? Micro Armor Fiber Cable is the ideal optical for you, never break a patch cord again! As is known, armored fiber cable can provide extra protection for fiber optic cable without sacrificing flexibility or functionality within fiber networks, featuring more robust and reliable when encountered with rodents, moisture, and other issues that may cause damage. The armored fiber cable is now optimal... -
Active Tap vs Passive Tap
When talking about network security and monitoring solutions, network access devices are the very first step in building an advanced visibility platform. The two most popular ways of monitoring traffic are using Network TAPs or port mirroring through a SPAN port. As covered in this article, a network TAP provides the most accurate way to copy the actual traffic that runs through a system... -
Fiber to the Desk (FTTD): Advantage, Deploy and Solution
In recent years, projects like FTTH (Fiber to the Home) and FTTB (Fiber to the Building) are carried out to provide better services for customers. To future capitalize on the benefits of optical cable, Fiber to the Desk (FTTD) is recommended for enterprises, financial institutions and federal agencies, which need high security and high data transmission speed. This article will guide you to have... -
CWDM vs DWDM – What is the difference?
Coarse Wavelength Division Multiplexers (CWDM) : CWDM stands for Coarse wavelength division multiplexers. A CWDM system commonly supports eight wavelengths per fiber and is designed for short-range communications, using wide-range frequencies with wavelengths spread far apart. These are modules that increases the amount of bandwidth the fiber optic system will carry by transmitting multiple signals at various wavelengths along the fiber optic cables. Since...
