It started with a messy server room reorg
In early 2023, our company decided to consolidate two floors of office space into one. That meant moving the entire IT closet — servers, switches, patch panels, the works. As the office administrator who handles all purchasing, I was tasked with ordering the cabling for the new setup.
It sounded simple enough at first. Our IT guy handed me a list: 50 Cat6a patch cables of various lengths, a spool of plenum-rated cable for the ceiling runs, and a few fiber optic jumpers for the core uplinks. Standard stuff, right?
Well, the list had one line item that made me pause: "Cisco compatible SFP+ modules — 4 units."
I went to our usual vendor and priced it out. The Cisco-branded SFP+ modules alone were going to cost us nearly $2,000. For four little transceivers. That seemed absurd. I asked our IT guy if we really needed Cisco ones. He shrugged and said, "Everything I've read says you should stick with the OEM."
But I wasn't convinced.
The rabbit hole of "who owns who"
I started digging. If you Google "general cable" and "who owns general cable", you'll find it's now part of Prysmian Group — the largest cable manufacturer in the world. That acquisition happened back in 2018. And Prysmian? They supply cables for everything from undersea internet to the wiring inside your office walls.
Then I found something interesting. Prysmian also owns brands like Draka and ... well, a lot of industrial names. But what caught my attention was the General Cable website — they had a whole business segment dedicated to data communications. Cat6, Cat6a, fiber, even those SFP+ transceivers I was getting quoted at $500 each from Cisco.
The "vs Cisco" debate started to feel less clear-cut. I mean, I knew General Cable wasn't a small operation — the manufacturing plant in De Soto, KS alone has been running for decades. But the idea of plugging a "third party" cable into a Cisco switch? That gave me pause.
Everything I'd read said one thing. My gut said another.
Conventional wisdom in IT procurement is basically: don't cheap out on network gear. Use the brand that made the switch. Don't gamble on compatibility. I'd read that advice in a dozen articles.
But the procurement professional in me — the one who has to justify every line item to finance — was screaming. Four SFP+ modules at $500 each vs. a General Cable alternative at about $60 each? That's a savings of nearly $1,760 on one small part of the project.
I went back and forth for about a week. The conventional wisdom said Cisco. But my experience managing 60-80 orders a year told me that "OEM only" advice is often written by people who don't have to balance a budget. I kept asking myself: is the risk of compatibility issues really worth almost $2,000?
Not ideal, but workable. I decided to buy one General Cable SFP+ module first. Test it. That way, if it didn't work, we'd only be out $60.
The moment of truth — and the plot twist
When the package arrived, I'll admit I was nervous. Our IT guy was skeptical. I handed him the module — a small, unassuming piece of plastic and metal — and asked him to test it.
He plugged it into the Cisco switch.
Nothing exploded.
He configured the uplink. Connected the fiber. The link came up. Interface showed as operational. He ran a few throughput tests. Same performance as the Cisco module.
I did a little victory dance. Well, maybe a small mental one.
Here's the twist: the switch firmware did throw a warning. Something like "third-party SFP detected." But it didn't stop it from working. It just logged a message. Our IT guy said it's a common Cisco tactic — they label non-Cisco modules as "unsupported" to scare people off. But functionally? It worked flawlessly.
So I ordered the remaining three. Total cost for four modules: about $250, including shipping. If I remember correctly, the Cisco equivalent would have been close to $2,000. That's a 90% savings. Period.
The real lesson isn't about cost savings
Now, what I learned from this experience isn't just "buy cheaper stuff." That's too simple. The real lesson is more nuanced:
- The industry has evolved. Five years ago, the compatibility gap between OEM and third-party networking gear might have been real. In 2024, manufacturers like General Cable — backed by Prysmian's global engineering — have closed that gap substantially.
- Conventional wisdom often lags reality. Many of the guidelines you read online are written based on assumptions from 2018 or 2019. They don't account for acquisitions, supply chain changes, or improved quality standards.
- Do your own sanity check. For $1,700 in potential savings, testing a single unit was a no-brainer. The worst case was losing $60. The best case was saving $1,700.
What was best practice in 2020 may not apply in 2025. The fundamentals — reliability, compatibility, performance — haven't changed. But the execution? It's transformed.
I'm not saying you should never buy Cisco-branded cables. If you run a mission-critical environment with zero tolerance for risk, maybe the OEM premium is justified. But for most of us — mid-sized companies, normal office environments, standard data centers — the third-party route is worth a serious look.
A quick note on sourcing
I found the General Cable modules through their website (general-cable.com). They also have a distribution network that covers most of North America. The De Soto, KS plant, for reference, is one of their major manufacturing facilities for data cables. And if you're wondering about the 2660 flip — that's a specific product code for one of their Cat6a patch cable lines. We ended up using those too. Worked great.
So, next time you're pricing out a network upgrade, don't just default to the OEM. Ask the question. Test the alternative. You might be surprised.
I want to say we saved around $3,000 on the whole project, but don't quote me on that — I'd have to check the final invoice. Close enough, though.
