The sheer volume of data being transmitted, processed, and stored is leading to the inevitable migration to 100G. Data centers and enterprise networks have the critical task to effectively migrate existing infrastructures to higher network speeds.
With network upgrades and high-density installations come cost and space challenges. The QSFP28 Compatible Optical Transceiver is a low-power, high-density device used to reduce 100G deployment costs and complexities. The smaller form factor saves space and reduces networking equipment costs, allowing organizations to optimize their existing fiber cable infrastructure.
Selecting the correct QSFP28 transceiver can be as easy as evaluating the existing fiber cabling and application. Here’s a Quick Selection Guide to help you configure your fiber connection applications to the correct 100G transceiver type.
If your fiber connection is Multi-mode 12F MPO and you’re running the connection over OM3 Multi-mode Fibers, then you would use a QSFP28-SR4 Transceiver.
If your fiber connection is Single-mode Duplex LC under 2km, then you would use a QSFP28-CWDM4 Transceiver, and so on…
ProLabs offers a complete portfolio of 100G Compatible Optical Transceivers, including CFP, CFP2, CFP4, and QSFP28 transceiver options, including extending distances with 100G Long Reach in an efficient QSFP28 package and a green solution which consumers 30% less power. Contact us to learn more about how our solutions can help you simplify and optimize your migration to 100G.

No matter how big a city is, the basic goal for a government is to guarantee residents’ safety. National Highways Authority of India(NHAI) was eager to solve some difficult problems caused by the cameras in their old video surveillance system, such as car plate number is not unrecognizable during nighttime. In 2015, NHAI decided to turn to use UNV products. Nowadays, 231 toll stations in Indian have being protected by UNV high quality products for more than 3 years.
National Highways are the arterial roads of a country for passengers and goods. In order to manage the vehicles’ status and information, there are more than 1300 UNV cameras and more than 200 NVRs installed over 231 toll stations in India. Over the past three years, UNV products never failed to provide the best quality image during day and night, ensured every vehicle’s information was recorded and were easy to be searched.
Besides, UNV products brought many other benefits to NHAI. For instance, with wide voltage range of ±25%, UNV cameras can work very well under unstable voltage. With ANR cache restores function, even if the network is not stable, the camera can swiftly change to save the video into the memory card. And after the network connected again, the video would be automatically sent to the local storage in the toll station.
“I believe in UNV products, because they are stable and professional. They can satisfy our requirement of high quality image during day and night. Except our toll stations, there are some airports and high-end hotels also using UNV products. Uniview now is a very popular brand in security industry and is believed to be able to provide reliable and high quality products.” Said a user from NHAI.

Dark fibre is essentially optical fibre infrastructure that is not in use. The term “Dark” referring to the fact that data is not being transported, so there is no light.
Dark fibre networks arise because when laying down network infrastructure, operators and utility companies will often over estimate the amount needed, future proofing their growth and cost, but this means that there could be thousands of miles of fibres across the globe which are not being used.
Our ever-increasing appetite for faster bandwidth speed is driving the demand for organisations to lease these unused fibres, freeing up valuable capacity. These dark networks could be one of the answers to fibre exhaustion and offer a cost effective alternative to the time, effort and labour intensive task of laying new fibre.
Mobile operators use leased lines to connect their masts and demand is increasing as we consume more data on the move. The introduction of next generation 5G mobile networks in the next few years is expected to further expand the market as operators plan to build more masts.
Adding wavelength division multiplexing (WDM) to a dark fibre network, doubles capacity on a single fibre, helping to achieve high connectivity, while keeping costs down.
WDM – CWDM and DWCM
Put simply, WDM adds multiple signals to the same fibre pair, using different colours of light. CWDM (course wavelength division multiplexing) and DWDM (dense wavelength division multiplexing) solutions allow multiple channels, traveling in either direction, to be simultaneously combined over a single fibre, meaning signals can be multiplexed into existing infrastructure, reducing the number of dark fibres needing to be leased.
