If you’re searching for general-cable connectors, you’re probably trying to figure out if a specific device will work in your 5G or FTTH network—or why a connector failed during a rush install. I can’t speak for every brand, but I’ve coordinated hundreds of rush orders in the last 3 years, and I’ll answer the questions I get asked most often. Some of these I learned the hard way.
1. What is a connector in optical networks, and why does the connector type matter?
In simple terms, a connector is the tiny plug on the end of a fiber cable that links a device to the network. If you’ve ever tried to plug a USB into a port and it didn’t fit—that’s the same problem at a much smaller scale. Different connectors (like SC, LC, ST) have different shapes, sizes, and insertion loss ratings.
From the outside, it looks like one connector is as good as another. The reality is, using the wrong connector type can triple your signal loss. For example, a general-cable LC connector is standard for high-density 5G backhaul, while an SC connector is more common in FTTH deployments. If you mix them without a proper adapter, you’ll introduce attenuation that no one planned for.
2. Can I use a general-cable website recommended connector for an emergency 5G installation?
Short answer: yes, but you have to check the specs first—especially if the order is rushed. In March 2024, I got a call at 4 PM on a Friday. A client needed 200 connectors for a 5G small cell install the next morning. Normal turnaround for custom terminations is 5 days.
The numbers said go with a generic LC connector that was in stock. My gut said to verify the polish type. Turns out, the generic option had a flat polish (PC), but the client’s equipment needed an angled polish (APC) to prevent back reflection. We found a vendor who could swap at an extra $400 in rush fees on top of the $800 base cost. We delivered, but the client’s alternative was a $50,000 penalty for missing the network activation window.
Always verify the polish type before you order. The general-cable website lists compatibility for its own products, but for third-party devices, you need to cross-reference.
3. How do I know if a connector is causing problems in my FTTH network?
People assume a dirty connector is the only cause of signal loss. Actually, the most common issue I see is a mismatch between the connector’s core diameter and the device’s fiber core. For FTTH, you’re typically looking at a 9/125 micron single-mode fiber. If someone uses a 50/125 multi-mode connector by mistake, your network will barely detect the light.
Last quarter alone, we processed 47 rush orders for replacement connectors. About 30% were because the original connector’s end face had been scratched during installation. The other 70%? Wrong core size or wrong ferrule material. Ceramic ferrules (zirconia) are standard for single-mode. Plastic ferrules are cheaper, but they’re not reliable for outdoor FTTH drops.
4. Can I repair a damaged connector in the field, or do I need a new device?
This worked for us, but our situation was a large-scale FTTH rollout with a strict timeline. When a connector got snapped off during installation, we tried to re-terminate it in the field with a standard splice-on connector kit. The success rate was about 60% on the first try. The other 40% caused even more loss because the cleave wasn’t perfect.
If you’re dealing with a general-cable pre-terminated assembly, I’d recommend replacing the entire pigtail if your timeline allows. It’s $15–25 per connector versus $5 for a field kit, but you save hours of troubleshooting later. I can only speak to installations where the environment is dusty or humid. If you’re working in a clean indoor data center, field repair is fine.
Quick tip: Always carry a fiber inspection scope to check the connector face before connecting. It’ll save you 30 minutes per link.
5. What does general cable du quoin photos have to do with connector selection?
I admit I didn’t immediately make the connection either. I was searching for general cable du quoin photos because a client forwarded me a photo of a damaged connector, and I needed to match the brand. Du Quoin is an important manufacturing and distribution center for General Cable—now part of Prysmian Group. The facility has been making cables and connectors for decades.
People think it’s just a factory. The photos (available on their website and industry trade sites) show how connectors are assembled, tested, and packaged. If you can see the photo of a specific connector model, you can verify the keying and footprint before placing a rush order. It’s saved me three times already.
Note: Prices and availability are based on publicly listed rates as of January 2025. Verify current pricing before purchasing.
Bottom line
Choosing the right connector comes down to:
✔ Know the fiber type (single-mode vs. multi-mode)
✔ Check the polish (PC vs. UPC vs. APC)
✔ Match the ferrule material to the environment
✔ Verify compatibility via the general-cable website or photos
An informed customer asks better questions and makes faster decisions. I’d rather spend 10 minutes explaining options than deal with mismatched expectations later.
