ShowMeCables keeps an inventory of 15,000+ products. And yet we realize that, for some of you, 15,000 is not enough.
Sometimes you need connectivity products in nonstandard lengths and configurations. For instance:
- Unique combinations of cables, connectors and adapters for Ethernet, fiber optics, RF coaxial and more
- Specially made antennas
- Weatherproof NEMA enclosures with pre-installed mounts or equipment
SMC offers these types of custom products and more, and this blog post reveals how surprisingly easy it is to get them. But first, if you’re undecided whether custom connectivity is the way to go, let’s summarize the three main benefits of such products.
Custom Products Last Longer
Going custom means choosing a product that is designed for a certain purpose. A custom wireless antenna handles the exact gain and frequency you need. Mounting plates in a custom NEMA enclosure can be metal or nonmetal for RF applications. When your installation operates within the electrical parameters, tolerances and environmental conditions it was intended for, it will perform better and last longer. Less maintenance will save you money.
Custom Products Mean Less Was

Multimode fiber optic cable supports high bandwidths, works great at shorter distances, has a larger core size that is easy to terminate and is usually cheaper than single-mode fiber cable.
So, why do so many people prefer single-mode fiber?
This blog post explains the benefits and uses of single-mode fiber optic cable, as well as the differences between single-mode simplex and duplex.
Single Mode: Stronger Signal, Longer Distance
Single-mode fiber optic glass has a narrower core than multimode and light travels a single path (mode) through it. Single mode’s smaller core minimizes reflection of light passing through, so there is less signal attenuation, or loss of strength. This allows single-mode fiber cable to transmit over distances up to 62 miles or more, and with virtually unlimited bandwidth. Applications include longer distance LANs, telephony and cable TV, although it is used in data centers as well.
Multimode fiber has a much larger core diameter and light travels multiple paths through it. It has more signal attenuation and thus is best for shorter distances, typically a maximum of 1,000 to 1,800 feet. Also, it is generally less expensive than single mode, which requires the use of pricier single-mode fiber optic transceivers. A fiber optic transceiver converts an electrical signal to an optical (light) signal and vice versa.
Simplex vs Duplex Fiber
If you choose a single-mode fiber optic cable, you can get it in either simplex or duplex. A simplex f

The Main Specs and Applications for Cat5e, Cat6, Cat6a, Cat7 and Cat8
Though there is a lot of talk about wireless and fiber optic connectivity these days, the business world still revolves around Ethernet cables. In most corporate offices, the PCs are connected via Ethernet cables to a central network hub or switch. The cables allow employees to communicate with one another on the network and to access files from servers.
Copper Is Still King
It’s true that copper wires cannot move data as fast as fiber optic cables, and take more work to install than wireless connections. But through the years Ethernet cables have become steadily faster and able to handle more and more bandwidth while remaining less costly than fiber. Also, they offer tighter cybersecurity and more control over access than Wi-Fi.
It is no wonder that most networking devices are still built with RJ-45 connectors. But Ethernet cabling can be confusing, considering all the cable categories that have been introduced over the past 20 years. To help you simplify your purchase decisions, we at ShowMeCables offer a summary of the main specifications and uses of the most popular categories: Cat5e, Cat6, Cat6a, Cat7 and Cat8.
- Bandwidth: 100 megahertz (MHz)
- Maximum data rate: 1 gigabit per second (Gbps) at up to 100 meters (328 feet)
- A big but affordable upgrade over the 10 to 100 megabits p

How to Find What You Need, from DisplayPort to Thunderbolt 4 to HDMI to RapidRun
Gone are the days when hooking up an audiovisual system required only speaker wire and a few S-Video and RCA cables. Today’s AV components do so much more, and with faster data transfer speeds, higher image resolution and pristine sound reproduction.
Of course, such advancements would be impossible without the AV cable assemblies that connect these components. Since starting out in 1995, ShowMeCables has kept pace with the latest trends in audio video cable assemblies. Below we summarize what you will find in our inventory.
Let’s start with the three categories where we have made our latest AV cable additions – DisplayPort 2.0, HDMI 2.1 and Thunderbolt™ 4. All three will allow you to upgrade your conference room, medical device, theater, AV screen or gaming setup to the latest in high-speed, high-definition standards.
DisplayPort 2.0 Cable Assemblies
DisplayPort 2.0 enables up to a threefold increase in video bandwidth performance. It has a maximum link rate of up to 20 gigabits per second (Gbps) per lane and features more efficient 128-bit/132-bit channel coding, delivering a maximum payload of 77.37 Gbps. DisplayPort 2.0 is the first standard to support 8K resolution (7,680 by 4,320 pixels) at a 60 Hz refresh rate with full-color 4:4:4 resolution, including with 30 bits per pixel (bpp) for HDR-10 support.

If you Google “Ethernet patch cable” you will get over a million hits. But while shopping for them can be confusing, you really only have to know four main things:
- What exactly is a patch cable?
- What are the main differences of the cable categories?
- What are your form factor options?
- What are your cable jacket options?
What Exactly Is a Patch Cable?
In a typical corporate office, the PCs are connected via Ethernet cables to a central network hub or switch, located in an IT room or closet. The hub or switch allows the PCs to communicate with one another on the network and to access files from servers. Also in the room are other network devices such as servers, routers and network media players. All these devices are connected, typically through patch panels. With its multiple ports, a patch panel is a switchboard of sorts that employs short Ethernet patch cables with connectors on both ends to make it easier to reconfigure the routing of the devices.
So, Ethernet patch cables, aka patch cords, are basically short Ethernet cables with connectors on both ends. They are used with patch panels, VoIP (voice over internet protocol) phones, Ethernet switches, and routers, and to connect workstations to wall outlets.
What Are the Main Differences of the Cable Categories?

You may have heard differently, but it is indeed possible for your organization to have data, voice and video transmission lines that are both robust enough to last a long time AND cost-effective and economical.
The key to having both benefits at once is to buy your Ethernet cable in bulk from ShowMeCables. We offer more than 100 types of bulk cable, which typically come in spools of 1,000 or 500 feet. You can also get shorter rolls of any length down to 1 foot.
Buying in bulk at SMC costs less than ordering shorter Ethernet cable assemblies, but without compromising quality. Here’s how we manage to do both.
How Bulk Cable Will Save You Money
Lower cost per foot. You will save money by buying cable in bulk. For instance, a 500-foot or 1,000-foot roll of Cat5e, Cat6, Cat6a or Cat7 Ethernet cable can cost from 20% to 80% less than when it’s purchased in short segments. Also, with bulk Ethernet cable you can cut it to the exact lengths you need, which means shorter, more efficient connections and less wasted product.
Quicker maintenance. Eliminating the mess of excess cable also makes it easier to install, remove or re-route cords and to troubleshoot wiring problems. Faulty connections are easier to find in a well-ordered installation, which means les

Whether your company’s data center is a big room or a small closet, it will be more functional if it is well organized. At ShowMeCables we are passionate about well-ordered data centers. Many of our 15,000+ products exist to make your job easier by organizing your IT equipment.
The two main types of these products are equipment organizers and cable organizers.
The best way to organize and protect your electronic components is to put them in either floor-mounted racks or wall-mounted racks.
Most companies install their servers and related IT equipment together in floor-mounted racks, aka server racks, which hold not only computer servers but patch panels, network switches, power distribution units and other components related to the network. They are floor-mounted on feet or on wheels, and some have a wall-securing option. They offer up to 45U of vertical capacity and depths of up to 42 inches.
Floor-mounted server racks offer four big benefits.

A large office might keep its computer servers in a data center while a smaller one can get by with an IT closet. But there is one thing most offices have in common: Their servers and related IT equipment are installed together in server racks.
Server racks hold not only computer servers but patch panels, network switches, power distribution units and other components related to the servers. They are either floor-mounted on feet or on wheels, or wall-mounted. Server racks are popular because they serve four crucial functions.
ShowMeCables’ server racks have several features for keeping your equipment cool. They have built-in fans to enable thermal management. Doors and side panels are vented for circulation. On most models, top panels are either vented or have dedicated ports for installing fans. Some cabinets have cable-routing features that keep interiors less cluttered to promote air flow. For the best circulation, we offer open-frame racks.
