Furukawa Cat5e and the Cost of a Supplier Who Says “Probably”

A supplier once told me a delivery would “probably” arrive by Friday. It didn’t. The cable showed up the following week, after I’d already paid extra to solve the problem with someone else.

So let me get my opinion out at the beginning: when a purchase is tied to a deadline, the delivery date is part of the specification. I’d rather pay a known amount for a supplier who owns the date than save money with a supplier who just hopes it works out.

I manage purchasing for a 50-person engineering firm. That means I buy a lot of unglamorous things—toner, work gloves, access cards, network cable. I process roughly 60–80 orders a year and manage maybe eight active vendors. The budget amounts to around $200,000. Most orders are routine. A few, though, can turn bad very fast if they show up one day late.

The Furukawa Cat5e order that shifted my view

In March 2022, we needed ten 305-meter boxes of Cat5e cable for a floor renovation. The low-voltage contractor was booked for March 21 through March 25. If cable was not on site by Friday, March 18, they would move us to April.

The first quote came from a distributor that stocked Furukawa cable. The total was $2,240, and the delivery appointment was explicit: March 17, 8–11 a.m. The second quote came from an online seller offering generic Cat5e for $1,940. I asked about timing; the rep said “usually ships in 3 to 5 business days, so probably by then.”

I did the math the wrong way: $300 in savings looked better than a delivery estimate. I ordered the cheaper cable.

What I didn’t notice was that “probably” is not a date. The order confirmation created a shipping label on March 10. On March 16, it still had not been scanned by a carrier. On March 17, the cable wasn’t there. I called and got a runaround: “we can’t guarantee delivery dates.”

I canceled the order before it went anywhere. Then I called the distributor with the Furukawa quote and asked what it would cost to get the cable that same day. The premium: $725. I said yes. The cable arrived at 4:12 p.m. and the job started Monday.

I paid $725 for a problem that never should have existed. The cheaper quote was not cheaper; it was just less committed.

If you buy cable in Brazil, you’ll see this same product listed as “cabo de rede cat5 Furukawa.” We have offices in São Paulo, so that phrase is familiar. But the lesson isn’t about the brand or the language. It’s about treating the delivery commitment as a technical requirement.

What changed in my buying process

Now I ask about dates before I ask about discounts. If a purchase is tied to a fixed need, I really only care about three things:

• The latest date the supplier will put in writing.
• The person and number I call if that date slips.
• The cost to correct the miss—before they take the order.

Cat5e performance has standards, and TIA-568.2-D covers the electrical side. No standard covers “probably.” That means the delivery commitment is not a nice-to-have. It is part of the product I’m buying.

That doesn’t mean every purchase has to be premium delivery. If we are restocking toner or buying cable for a future project, I compare unit prices like everyone else. But when a date matters, the cheap quote without a firm date is the riskiest option on the table.

Isn’t “known date” just code for paying more?

Sometimes. In a normal year I process about 70 orders; only a handful actually justify paying extra for certainty. The rest have enough buffer that standard delivery is fine.

But on the few orders where a supplier can take a date from me or give me one, I no longer pretend the cheaper estimate is a better deal. From the outside, the low quote looks efficient. The reality is that the supplier is letting me carry the risk of their schedule. I’ve learned that the hard way.

My sample here is one office manager at one mid-size company. If you buy commodity items with no deadline attached, ignore my rule and buy cheap. That is the right approach. But if you have ever stood in an empty room waiting for a contractor who arrived on time, you know the price of a late delivery doesn’t stay on the vendor’s invoice. It lands on your department.

Bottom line

I still buy Furukawa cable, but not because I think it is magic. I buy it because the people who sell it to me give a date and hit it. When that stops being true, I will find another supplier who does the same.

So here is my plain opinion: certainty has a price, but uncertainty has a larger one. I know which bill I prefer to pay. Next time a supplier says “should be there,” ask for a date. If they can’t give one, they are telling you how much risk you are about to carry.
