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....

It is quite common when we receive questions from our customers as this example “Hey – we have available one dark fiber between our two network nodes and we need to organize 6x10G bi-directional links over that fiber and distance is about 30km. Future plans...

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...

Mobile traffic is booming and this evolution is backed up by both the evolution of 4G and the coming introduction of 5G, which will deliver a downlink user experience of 100Mbps everywhere and 1-10Gbps locally, with a latency of less than 1ms. Such increase in...
