The CK Daily – Get To, Not Got To
Good Morning CK Fam!!
Sometimes we really need to put things into perspective to really appreciate what we have and where we are at in life.
The title of this entry is get to, not got to. It’s because we all get to. We get to have coffee this morning. We get to have clean, running water. We get to go to a job to provide for ourselves and our families.
I’m not an Alabama Football fan, but you certainly don’t have to be to enjoy (and share) this five-minute video of Ernie Johnson speaking to them about GET TO.
Don’t forget to remind yourself and your loved ones that you get to today.
Appreciate you all – enjoy getting to embrace Monday,
Corey

Product Spotlights & Updates
Happy Monday CK Family! We hope you had a relaxing weekend and are ready to take on the week! Today we’re kicking off our deals by highlighting the Cisco 2960-X Series 48 Port 740W PoE+ Switch, WS-C2960X-48FPS-L.
Cisco has always done an amazing job with catering to small and medium businesses. The Cisco 2960-X series is another generation of the already popular 2960 series that will enable the typical small to medium business to function at an enterprise level without the enterprise budget. The 2960-X series switches offer a fixed configuration of Ethernet switches that are not only Gigabit, but also stackable. The 2960-X was specifically designed for easy deployment and operational efficiency. These switches are also energy cautious and have a large range of IOS software features.
Switching capacity on the 2960-X series come in twenty-two percent higher than the 2960-S units as they have a total capacity of 216 Gbps. Each switch will offer either two 10 gig uplinks or four 1 gig uplinks and zero-touch configuration as well as IOS software updates when you are deploying the 2960-X switch.

What is the difference between OS2, OM1, OM2, OM3, OM4, and OM5? – CK Learning Center
When it comes to fiber-optic networks, there are a lot of options in how a network is designed. Ultimately, the demands of the network will determine which cable is best for any given job, but you need to have a clear understanding of the different fiber cables in order to make that decision. While the complete list of design differences could fill several books, you can understand the key variations in design in a few minutes. This quick guide will highlight the characteristics of OS2, OM1, OM2, OM3, OM4, and OM5 fiber cables.
OS vs OM Fiber
The first difference to understand is the one that exists between OS and OM cables. The briefest explanation is that OS cables are all single-mode fiber, and OM cables are multimode fiber. If that provides enough clarity, feel free to skip to the next section.
For those who like more details, there are a few key design differences between the cable types. These differences mostly scale to the single- or multi-mode functionality. OS cables have much thinner cores than their OM counterparts. An OS cable, like OS2, will usually have a 9-micron core while OM cables can be over 100 microns. Additionally, OM cables are designed to work across shorter distances and with less expensive transmission parts.
OM Fiber Cables
If multimode fiber is the right build for a network, there are still important decisions to make. For the most part, the cables come in five separate designs (named OM1, OM2, OM3, OM4, and OM5 respectively). OM1 might be the older, slower guy on the market, but it is no less common in modern applications. It utilizes a 62.5/125-micron core and is known for its cost efficiency for short runs. The other three designs all work with a 50/125-micron core.
The next major difference is in transmission. OM1 and OM2 both use LED transmitters. These are great for their low cost, but the LED transmitters limit bandwidth. OM1 and OM2 cables hit top speeds of around 1Gbps. OM3, OM4, and OM5 cables utilize laser-optimized multimode (LOMMF) transmission. This is more expensive, but it enables higher bandwidths, and these cables can get speeds up to 10Gbps (OM3), to 40Gbps (OM4), and up to 100Gbps (OM5).
Other, subtler differences can be found among these varying cables, but in terms of application, this is the bulk of the story.
OS Fiber Cables
As for OS cables, they come in OS1 or OS2 builds. OS1 is a bit antiquated. It is designed for distances less than 2km, and it hits a top transmission speed of 10Gbps. For jobs in that range, there are usually OM designs that are more cost-effective. OS2 is the standard for long-range networking. The cables can carry signals up to 200 km, and they can achieve transmission rates in excess of 10Gbps.
The purpose of OS2 fiber cabling is to do work that is best suited by single-mode fiber optics. It’s the easy go-to for long-range, high-speed work.
We like to keep things simple and straightforward. In almost every case, the best cable will be the one that meets your distance and speed needs at the lowest possible cost.
