There's no single "best" EXFO device
When I first started managing equipment purchases for our network team, I assumed there was a clear winner. You know—the one OTDR or power meter that everyone should buy. I was wrong.
After five years and about $120k annually across test equipment vendors, here's what I've learned: the right EXFO tool depends entirely on your team's workflow. Not on specs alone, not on price, and certainly not on what your competitor is using.
Let me break this into the three most common scenarios I've seen—and helped navigate.
Scenario A: The large-scale deployment team
What you're dealing with
You're rolling out fiber to hundreds of premises per month. Your techs are in the field full-time, swapping between FTTH builds and metro backbone work. You need rugged devices that survive pickup trucks and rain, and you need them to do multiple jobs without returning to the shop.
What I'd recommend
For this crew, the EXFO MaxTester 715B is hard to beat. It's a handheld OTDR with PON power meter built in. One device, one rugged shell, and it handles both troubleshooting and acceptance testing.
(Note to self: Our field team ran 200+ tests per week on a 715B for 18 months. Zero failures. That's the kind of stat you don't forget.)
But here's the counterintuitive part—I'd not buy the MaxTester for every single tech. If someone is purely doing splitter testing or power verification, a simpler PON power meter (like the EXFO PPM-350) is cheaper and faster. The 715B's extra features would just be wasted weight in their tool bag.
What about a DWDM OTDR?
If your deployment involves DWDM or CWDM networks, the EXFO DWDM OTDR (part of their FTB-1v2 or MaxTester line) is the right call. But don't buy it unless you're actually testing DWDM spans. I've seen teams overspend on DWDM-capable units when 99% of their work is standard single-mode fiber.
"The vendor who said 'this DWDM OTDR isn't necessary for your use case—here's the mid-range alternative' earned my trust for everything else."
Scenario B: The mid-sized engineering team
What you're dealing with
Maybe you're a 30-person company supporting a regional network. Your engineers wear multiple hats—one week they're on a truck, next week they're in the lab. You need portable gear that's still lab-grade accurate. And you need it to integrate with your existing reporting software.
What I'd recommend
This is where the EXFO C300 series comes in. It's a modular test platform that can be configured for OTDR, optical channel checking, and even Ethernet testing. One chassis, multiple roles.
I went back and forth between the C300 and individual handhelds for two weeks. The C300 offered flexibility, but the handhelds were cheaper per unit. Ultimately, I chose the C300 because our engineers needed to switch between testing protocols in the same day—and carrying three devices wasn't practical.
Looking back, that was the right call. But if I could redo one thing, I'd have spent more time upfront training the team on the software interface. (Honestly, I assumed it was plug-and-play. It wasn't. Budget for training.)
What about DWDM channel checking?
For mid-sized teams that support DWDM networks but don't need a full OTDR every day, the EXFO DWDM Channel Checker (like the OCC-4056C) is a smart middle ground. It's cheaper than a full OTDR and faster for verifying channel power levels. Not a replacement—a complement.
Scenario C: The small team or specialized technician
What you're dealing with
You're a two-person show, or a contractor who handles specific fiber jobs. Maybe you do mostly connector inspection and power verification. You don't need a fleet of devices; you need one reliable tool that does the core job well.
What I'd recommend
Honestly, start simple. An EXFO PON power meter and a fiber microscope (like the EXFO FIP-400B) will cover 80% of what most small teams need. Add an OTDR only when you're building new spans or troubleshooting hard-to-reach faults.
I've never fully understood why some technicians buy a $10,000 OTDR when they spend 90% of their time cleaning connectors and checking power levels. My best guess is they assume they'll grow into it. In practice, they just carry an expensive, unused brick.
If you do need an OTDR, the MaxTester 715B is still a good fit—just know it's overkill if you're not doing distance-to-fault work regularly.
How to figure out which scenario you're in
Here's the practical self-check I use with colleagues:
- Do you test fiber more than 20 times per week? → Scenario A: prioritize rugged, multi-function devices like the MaxTester 715B.
- Do you need to switch between testing types (OTDR, power, Ethernet) on the same job? → Scenario B: consider a modular platform like the C300.
- Is your testing limited to occasional verification and connector inspection? → Scenario C: don't over-buy. A power meter and microscope are enough.
And for the Cisco vs. EXFO question I hear in procurement meetings: they're not direct competitors. Cisco is the network build; EXFO is the network test. You need both. Any vendor who claims their kit eliminates the need for testing is overselling.
Final thought
The best procurement decision I ever made was admitting I didn't know which device fit our scenario. I asked my field team to shadow-test two different tools for a week. The feedback was immediate and clear.
(I wish I had tracked their preference with a simple survey earlier. What I can say anecdotally is that field techs overwhelmingly prefer a rugged handheld over a lab-accurate but fragile desktop unit.)
Be honest about your team's actual workflow. That honesty—not the latest spec sheet—will lead you to the right tool.
