In This Issue: 12U Freestanding Equipment Rack, 19″ | What are the different types of QSFP+ Transceivers? | News to Start Your Day
We’ve made it to the middle of the week! The week has seemed a bit long so far, but we hope you are hanging in there. Today is National Fajita Day! There really is a holiday for everything – but today is the day to enjoy the sizzling deliciousness of the savory Tex-Mex flavor found in fajitas!
The CK Daily – Change is Good
Happy Midweek! Someone send me some Kleenex! The day has finally come where my husband and I decided to send my toddler back to school and I can’t stop crying. After 17 months of listening to every single ABC song and seeing the movie Trolls over and over again, my house is back to its former self and is completely silent.
I know change is good, but why does it hurt sometimes? I began to realize change was coming when my son told me he wanted to go back to school. Even though he was home with my husband and me every day learning and thriving, we realized that we needed to cover our son in prayer and let him grow in a formal school environment.
Monday morning came faster than ever, and it was time for my son to go to school. We walked through the school doors, said Good Morning, and the teacher came and walked my son to his classroom. To my surprise, he took the teacher’s hand and walked away without saying goodbye or showing any fear.
It was at that point that I realized that this change was not only good for my growing son, but for myself as well. It is imperative that I expose my child to the many wonders of the world and allow him to soak up all the knowledge he can retain. It is also imperative for me to release my fear and sense of uncertainty and allow God to protect him while he is at school. This change now allows me to spend more focused time on work and myself, which is equally as important.
I say all this to say yes changes in life can shake up your world, but sometimes we need a little shaking! How do y’all adjust to change, because this momma has been a bucket of tears!
Hot Topic of the Day
Do you have an old cell phone? Hopefully, you’re able to update the model or version of software you have as YouTube will no longer work on some Android models and smartphones that have version 2.3.7 or lower of an operating system. Beginning September 27th, users who have smartphones with said operating system will no longer be able to log in to the Google suite (YouTube, Maps, Play Store, Gmail, and Google Photos).
Hopefully, you aren’t impacted by this change, but we feel for you if you are! What we want to know is – Are you a fan of YouTube? What’s your favorite video/channel to watch? Head on over to the CK Facebook page and share your favorite – bonus points sharing a link!
Product Spotlights & Updates
We’ve made it to the middle of the week! Anyone else think the week is flying by? To keep this week moving we’re showcasing the 12U Freestanding Equipment Rack!
Not every installation requires a full 6′-7′ equipment rack. When you are mounting just a few pieces of gear, or space is limited, using a smaller more compact rack is the key to getting the job done with the space you have.
This freestanding 12U mount is perfect for labs and SOHO network installations. The rack is big enough to hold 12 1RU units and strong enough to hold up to 75lbs. The black, powder-coated steel frame is angled back to better support the weight of the mounted gear giving it a better center of gravity. This rack is light, weighing in at only 7lbs, and small enough to fit either on top of, or below a desk or table.
When space is limited and the install is small, this compact racking solution will fit the bill!
What are the different types of QSFP+ Transceivers? – CK Learning Center
There’s been a rapid evolution of gigabit ethernet and a growing demand for equipment that handles this advancement. Data centers are now migrating to blazing-fast 40G, and QSFP+ transceivers as a necessary component in making sure high-speed internet stays high speed.
QSFP+ stands for Quad Small Form-Factor Pluggable Plus. A parallel and hot-swappable fiber optical module that provides high-density 40G connectivity options for high-performance computing networks and modern data centers. It has four independent receive and transmits optical channels that can terminate to another 40G QSFP+ transceiver, or can be distributed to four separate 10 Gigabit SFP+ transceivers. The QSFP+ modules, in a nutshell, connect the entire electrical circuitry of your system to an optical external network.
QSFP+ Interface: LC & MPO
There are a variety of 40G transceivers currently available on the market. However, 40G QSFP+ optics follow the QSFP MSA standard which dictates that 40G QSFP+ connectors can be either 12-fiber MPO or duplex LC. Which are the MPO and the LC. What are the differences between these two interfaces?
To put it simply, 40G QSFP+ transceivers that have an LC interface are used in transmitting data over long distances via single-mode fiber (SMF), while transceivers with an MPO interface (except for 40GBase-PLR4 and 40GBase-PLRL4) are deployed for data transmission over short distances via multimode fiber (MMF). In addition to that, MPO interfaced QSFP+ transceivers can be used in 4x10G connectivity using a breakout cable, compared to LC interfaced ones that can’t be divided into 4x10G since they use 4 wavelengths on one pair of SMF.
Let’s delve deeper and understand how 40G QSFP+ transceivers with LC interface work. From the transmitting side, 4 channels of 10G serial data streams that have different wavelengths are sent over to laser drivers. These same laser drivers control the DML or directly modulated lasers using wavelengths. Then the DML outputs are multiplexed optically to a single-mode fiber via a standard LC connector, combining as 40G. On the receiving side, the 40G signal is demultiplexed into four separate 10G streams at different wavelengths. Each single-wavelength light is acquired by a diode and amplified by a TIA and then comes out as electric data.
The working principle of a 40G QSFP+ transceiver with an MPO interface can be explained by starting from the transmitting side when it transmutes parallel electrical input signals into parallel optical signals via a laser array. The optical signals are then sent through the MPO-terminated MMF ribbon. On the other side, the receiver transforms parallel optical input signals into parallel electrical output signals using a photodetector array.
Which QSFP+ Type Is Right For You?
QSFP+ transceivers also come in several ratings. It is important to know which category best suits your network setup. As your partners in IT procurement, we are here to provide a series of cost-effective transceivers to meet your various network demands.
