25GBASE-SR Door de ontwikkeling van 100GBASE-SR4 in 2015 werd het noodzakelijk een nieuwe standaard te ontwikkelen voor een lagere snelheid in de vorm van 25GBASE-SR. Deze is in 2016 formeel vastgelegd als IEEE 802.3by Ontwikkeld voor het aggregeren van vier 25G server-poorten naar één 100G switch-poort De transceiver gebruikt de bekende SFP+ form factor met […]

Market for Optics Returns to Growth After a Slow Start of the Year
Sales of optical components and modules dropped sharply in the first few months of 2017 because of very low demand for these products in China. The situation in China remains uncertain, but the market for optical transceivers managed to return to growth in the second quarter of 2017, as shown in the figure below. Sales […]
Testing and structured cabling standards: Harmonization?
By SEYMOUR GOLDSTEIN, Fluke Networks — If you ever attended a Standards meeting you might have heard the word “harmonization” mentioned frequently. The idea of harmonization, somewhat of a holy grail, is to have standards from different organizations agree. For example, imagine if the TIA, IEC, and ISO/IEC organizations used the same test standard. Actually, […]
CS Connector – The Next Generation of Data Centre Connectivity by Senko
Senko’s new CS connector is specifically designed for Data Centre 400G optimization. Intended to complement the form factor of the next generation of (OSFP/ QSFP-DD) transceiver modules, the CS connector meets the requirement for 2x100G/200G CWDM4 transceivers requiring two pairs of TX/RX. Customer benefits include: 36 % reduction in size. Pitch is reduced to 3.8mm […]
FTTH project characteristics
To successfully built and implement modern FTTH network you need to realize how big work must be done and especially define basic parameters of such system. Design aspects: At this stage you need to elaborate a conception and project which will be developed at the next stages. System must be uniformed, based on well known, […]
What are the reasons a data center might consider installing OM5?
“OM5 offers a longer cabling reach than OM4.” The difference is minimal. For all the current and future multimode IEEE applications including 40GBASE-SR4, 100GBASE-SR4, 200GBASE-SR4, and 400GBASE-SR16, the maximum allowable reach is the same for OM5 as OM4 cabling. Based on application testing recently done with 40G-SWDM4 transceivers, it has been proven that OM4 could […]
