Introduction to Optical Amplifier (BA, LA, and PA)

Optical Amplifier (OA) is an important composition in WDM Transmission Network, it amplifies optical signals. TARLUZ Optical Amplifiers featured with real-time, high gain, broad width, on-line, low noise, and low attenuation. It is an essential component in a new-generation optical fiber communication system. based on the position of the Optical Amplifiers in the optical link, […]

WDM, Mux/Demux and OADM Over view

CWDM Mux/Demux The Coarse Wavelength Division Multiplexing-CWDM Mux/Demux is often a flexible plug-and-play network solution, which helps insurers and enterprise companies to affordably implement denote point or ring based WDM optical networks. CWDM Mux/demux is perfectly created for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and […]

Different types of WDM technology

Early WDM systems transported two or four wavelengths that were widely spaced. WDM and the “follow-on” technologies of CWDM and DWDM have evolved well beyond this early limitation. WDM Traditional, passive WDM systems are wide-spread with 2, 4, 8, 12, and 16 channel counts being the normal deployments. This technique usually has a distance limitation […]

How to install SFP Transceiver

Thanks for choose TARLUZ SFP Transceivers, The transceivers may compatible with different network devices from different venders, TARLUZ could offer Generic and compatible SFP Transceivers, CAUTION: When installing or removing a transceiver module, avoid touching the golden plating on the transceiver module with a bare hand. Do not remove the dust plug from a transceiver […]

WDM – Wavelength Division Multiplex WDM wird auch als Wellenlängenmultiplex oder Wellenlängenvielfach bezeichnet. Jede Farbe des Lichtes wird einer bestimmten Frequenz der elektromagnetische Welle zugeordnet. Durch die Verwendung unterschiedlicher Farben (Frequenzen) lassen sich auf einem Lichtwellenleiter mehrere Datenkanäle unabhängig voneinander betreiben. Diese Methode entspricht dem Prinzip des Frequenzmultiplexverfahrens. Wobei die Wellenlänge mit der Frequenz vergleichbar […]

Evolution of MPO Connectors

The MPO was created to provide highly reliable connections in high density fiber applications, primarily in interoffice data network environments. The connector was revolutionary and performed as advertised in its early years, and helped advance optical connectorization in subsequent decades. The data communications industry uses MPO connectors to connect fiber backbone in premises applications, mainframe […]

OM4 fiber optic cabling

What is OM4 ? Based on The New TIA/EIA Standard, OM4 is a laser-optimized, high bandwidth 50µm multimode fiber. In August of 2009, TIA/EIA approved and released 492AAAD, which defines the performance criteria for this grade of optical fiber. While they developed the original “OM” designations, IEC has not yet released an approved equivalent standard […]

OTN Technology Overview

The following technologies have a common goal of being able to route packet technologies (Ethernet) across a network in a deterministic way while providing a stable system with management and fault-finding abilities. Technologies such as SDH/SONET, which is connection-oriented, are very deterministic in routing and quality but they are also very inflexible with regards to […]

MTP MPO Trunk cables

On-site termination of an MPO/MTP® connector with 12, 24 or even up to 72 fibers is obviously no longer possible. In other words, if you use MPO connectors you also have to use trunk cables (Figure 11) delivered already cut to length and terminated. This approach requires greater care in planning but has a number […]

50um or 62.5um fiber for Data Center

In terms of physical properties, the difference between these two fiber types is the diameter of the core—the light-carrying region of the fiber. In 62.5/125 fiber, the core has a diameter of 62.5 microns and the cladding diameter is 125 microns. For 50/125, the core has a diameter of 50 microns with the same cladding […]
