25G SFP28 CWDM article focuses on Passive CWDM (Coarse Wavelength Division Multiplexing) 3rd generation which is one of xWDM technologies. Advancing from 10G Ethernet per channel to 25G Ethernet per channel. A short recap - CWDM multiplexes a number of optical carrier signals onto a...
400G Ethernet Transceivers introduction is so important right now as 400G Ethernet is the big thing that everybody is and will be talking about for years to come. 400 GbE is the next big step since 100GE. Being and staying informed and up to date...
When you expand or upgrade your Data Center, there can be a situation when you need to connect 10G SFP+ to RJ45 ports. Most Server NIC (Network Interface Card) and Storage Appliance units have fixed 10GBASE-T ports with RJ-45 connectors and on the other side...
25G SFP28 transceivers: Quo Vadis? Nielsen’s Law of Internet Bandwidth states that user’s bandwidth grows by 50% per year, and this law has held true for a period of 37-years, all the way back since 1983. Figure 1. Internet connectivity (bits per second) It is always interesting to...
100G PAM (Pulse Amplitude Modulation) are gaining ground in transceiver market and is encouraged by many but is it THE future? Many also say that future perspectives are grand, full with optimism as this technology is embraced by CISCO, HUAWEI, ARISTA to name a few....
Nowadays world information networks have become more inter-connected than ever. This can be attributed to advancements in multiple telecommunication sectors or as OSI calls it Layers. Each layer has had an integral part in rapid development of node to node connections and technology behind it....
Optical transceiver modules are the main end-to-end components which allows optical communication through optical fiber. Transceiver manufacturing technologies are developed over time to become faster and less susceptible to errors. Optical transceiver like any other high tech electrical appliance, during their manufacture process is undergoing...
The Internet has changed lives for all of us, but we believe it is only beginning. In recent years, the rapid development of IP and VPN has advanced data services - such as Internet access, IP-based virtual private networks and multimedia applications. This development requires...
One thing we can say for sure, world is constantly changing and evolving. If we take a look on Fortune 500 company list in 1955 and in 2016 only 12% of the companies which were on the list in 1955 are still on the same...
SFP type and BiDi SFP type optical modules are very popular and widely used in optical communication while CSFP (Compact Small Form-Factor Pluggable) optical transceivers are much more rare. In this article we would like to explain main difference between SFP, BiDi SFP and Compact...
