Today’s Topics: Bullet Journaling | Kendall Howard Rack Screws & Cage Nuts | What is an SFP & how do they work? | News to Start Your Day
March 8th is International Women’s Day! Today we celebrate the many achievements of all of the wonderful women in our lives. We are surrounded each day by incredible women, let them know you are proud of their success!
Good Morning! Another new voice here for the CK daily e-mail! My name is Amy Mai and I’m part of the sales and customer service team at CablesAndKits.com. My role involves a lot of planning and organizing. To keep myself on track of my personal and work life, I use a Bullet Journal.
If you never heard of a bullet journal, it is a hybrid of a personal journal and a daily planner. The Bullet Journal “explores what it means to live an intentional life, one that’s both productive and meaningful.” I’ve been using this system for almost 3 years already and I can’t imagine going back to a normal planner. The biggest pro of bullet journaling is that it’s 100% customizable! You can pick and choose what spreads you want, how your weekly formats look, how big or small your font will be, the possibilities are endless. This can also be a con for some. It’s very hard to start from scratch. I recommend reading The Bullet Journal Method by Ryder Carroll If you are thinking about starting one. Ryder Carroll is the creator of the Bullet Journal. Why not learn what it is from the creator himself! Here is also a link to Ryder Carroll setting up his own Bullet Journal: https://www.youtube.com/watch?v=GfRf43JTqY4&ab_channel=RyderCarroll
I hope you try this out! I look forward to talking to you in my next entry!

What is an SFP & how do they work? – CK Learning Center
High-end networking demands high-end equipment. You have a plethora of options, but eventually, you have to make decisions on which technology covers each of your applications. When considering all of those options, an understanding of SFP transceivers is pivotal. It’s a core technology that serves as a primary workhorse in many networks. This guide is going to explain all about SFP and its primary uses.
Starting with the basics, SFP stands for small form-factor pluggable. It’s also commonly called mini-GBIC (gigabit interface converter). SFP is a popular transceiver for three main reasons. First is the small form factor. Its size allows it to be used in tight networking spaces to provide fast communication between switches and important networking components. The second reason for its proliferation is the variety of SFP connection options. SFP works with copper or fiber optics. The networks that can’t utilize SFP are scarce. Finally, SFP is hot swappable. That makes it ideal for expanding or adjusting existing networks without having to redesign the entire cable infrastructure.
SFP is designed to work with the bulk of modern networks. On the copper side, you will primarily find 1000BASE-T and 1000BASE-TX modules for gigabit Ethernet networking. SFP modules are excellent for bridging communications between switches in compact environments, provided everything is within 100 meters.
On the fiber optics side of the equation, options are massive. SFP modules are made to support singlemode and multimode fiber. It works with simplex and duplex. Wavelength options range from 850 nm to 1550nm. Networking ranges are anywhere from around 500 meters to over 100 km. In all, there’s an SFP module for every job.
SFP compatibility is deceptively tricky. There is not a formal, regulated international standard for these modules. Instead, compatibility is found within the multi-source agreement (MSA). This is an agreement supported by a number of manufacturers that work together to try and provide a reliable means of mixing and matching SFP brands successfully.
The challenge is that, despite the MSA, SFP modules tend to work best when brands are not mixed. It creates an interesting obstacle for optimizing equipment costs. You can follow MSA guidelines and try to use lower-cost parts in different components of your network, or you can simplify compatibility and stay within a single brand. The trade-off is usually between equipment costs and deployment time, but overall, MSA compatibility can be used successfully in most networks.
Applications of SFP’s
With all of this talk about SFP, the inevitable question arises. When is it useful? SFP has a wide reach of applications. For copper modules, the most common use (as mentioned before) is bridging network switches. They provide fast copper connections without requiring bulky equipment.
In the realm of fiber optics, the applications cover anything that might involve high-speed and/or long-range cables. High-definition audio transmission and reception, passive optical networks (PON), multiplexing, and simplex networking are some of the most common uses of this technology. The variability of SFP allows it to provide modules for any of these connections, and it provides a range of options in cost, speed, range, and accessibility.
Since the development of SFP, modernized advancements have been added to the mix. Namely, SFP+ and QSFP are now available. SFP+ is a faster version of the same form factor. It supports speeds up to 10Gbps, and it typically works across shorter distances. SFP+ ports are usually compatible with SFP optics, but the reverse is not true. SFP+ cannot operate slower than 1Gbps.
QSFP (quad small form-factor pluggable) is another transceiver with a range of support options. Ethernet, InfiniBand, SONET and fiber channels are all supported. The primary difference between QSFP and SFP is the quad form. QSFP can hit speeds up to 100 Gbps by utilizing four transmission and reception channels. QSFP is the powerful upgrade for systems that require huge bandwidth.
Complete mastery of SFP modules requires more learning that might fit in a single article, but this is enough to get started. What matters is that you understand how frequently SFP modules can be used to bridge communications between devices. From there, it’s a matter of matching the SFP design to the rest of the network.
