La fibre la plus couramment employée dans le domaine des télécommunications demeure la fibre monomode G652.B & G652.D (standard UIT-T repris par la CEI 60793). Grâce à son faible affaiblissement linéique et à sa bande passante, elle permet la réalisation de liaisons longue distance à très hauts débits. Ces fibres sont préconisées dans les réseaux […]

Introduction to XGS-PON 10 Gigabit capable symmetric passive optical network
Recommendation ITU-T G.9807.1 describes a 10-Gigabit-capable symmetric passive optical network (XGS-PON) system in an optical access network for residential, business, mobile backhaul and other applications. This system operates over a point-to-multipoint optical access infrastructure at the nominal data rate of 10 Gbit/s both in the downstream and the upstream directions. XGS-PON systems are able to […]

What is SWDM Shortwave Wavelength Division Multiplexing
In 2015, the SWDM Alliance was formed by a group of transceiver, fiber and system vendors to develop a multi-source agreement (MSA) for SWDM transceivers. As OM5 permits the use of a much wider wavelength range, it is now desirable to reduce fiber count by transmitting multiple VCSEL wavelengths in the same multimode fiber. The […]
25G PON Technologies and Calls for Unified Next-generation PON Standards HUAWEI
[Shenzhen, China, April 18, 2017] At the fourteenth Huawei Analyst Summit held in Shenzhen recently, a Huawei speaker gave an presentation about the key symmetric 25G PON technologies that binding multiple wavelengths to deliver N × 25 Gbit/s bandwidths over a single fiber. Huawei called on the industry partners to jointly push for unifed next-generation […]
La Solution FTTx / FTTh
FTTh est l’acronyme de Fiber To The Home qui signifie « fibre optique jusqu’à la maison » en anglais. La solution FTTx rassemble toutes les solutions FTTh, FTTo (office), FTTd (desk)… Jusqu’alors utilisée principalement dans les réseaux de longues distances (transport et collecte) et réservée aux entreprises pour la partie desserte, la fibre optique s’approche […]
Introduction to OM5 (WBMMF) Fiber
ISO/IEC decided to name WBMMF Wideband Multimode Fiber as OM5 in Oct. 2016, this decision was made by ISO/IEC Joint Technical Committee 1 (JTC 1)/Subcommittee 25 (SC 25) Interconnection of Information Technology Equipment. At a spring 2016 meeting of JTC 1/SC 25’s Working Group 3 – Customer Premises Cabling – the working group was unable […]
What you should know about ADSS Cable
ADSS cables. All-Dielectric Self Supporting cables. The All-Dielectric Self Supporting (ADSS) cable is a completely non-metallic structure in which the tensile load bearing elements are integral within the circular design of the cable – usually in the form of aramid yarns or stranded glass reinfroced plastic rods. The structure of ADSS Cable Typically a loose […]
