What is DDM or DOM for Optical Transceivers

What Is DDM (Digital Diagnostic Monitoring)? DDM is short for Digital Diagnostic Monitoring, according to the industry standard MSA (Multi-Source Agreement) SFF-8472 and is also known as DOM (Digital Optical Monitoring). When choosing the fiber optic transceivers for your equipment, you can choose transceiver modules with or without DDM/DOM function. Most of fiber optic transceivers […]

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 […]

Introduction à la fibre optique

Une fibre optique est un fil en verre ou en plastique très fin qui a la propriété d’être un conducteur de lumière et sert dans la transmission de données par la lumière. Elle offre un débit d’information nettement supérieur à celui des câbles coaxiaux et peut servir de support à un réseau « large bande […]

Introduction to Non-contact MPO Fiber Connectors

The Non-Contact MPO fiber connector (NC-MPO) invented by Arrayed Fiberoptics, it might be the next generation multi-fiber optical connector for data center project, where there is no contact between fiber surfaces. There are two key elements in the NC-MPO connector, first, the fiber surface is recessed, and second, the fiber surface has an anti-reflection coating. […]

Multimode (OM1, OM2, OM3, OM4, OM5) and Single Mode (OS1, OS2) Fiber

What are OM and OS type fiber optic cables? In ANSI/TIA-568.3-D, the TIA adopted the nomenclature for fiber found in the international standard ISO/IEC 11801. The multimode fiber is prefixed with “OM” and the singlemode mode “OS”. The new designation in ANSI/TIA-568.3-D should alleviate some of the confusion associated with application support distance issues. Each […]
