Choosing the right tool for an RF network cable telecom test comes down to one practical question: do you need a basic cable check, or a single instrument that also reaches into PoE and optical troubleshooting? The NOYAFA NF-8508 is aimed at the broader end of that decision, so its fit depends on the range of jobs you expect to handle.
Quick verdict
The NOYAFA NF-8508 is a 9-in-1 LAN Ethernet cable tester priced at USD 68.95. It combines copper-cable diagnostics with PoE identification, optical power measurement, and visual fault locating. Choose it when that range matters; otherwise, its broad scope is the main question to resolve.
Who it suits
The NF-8508 fits shoppers working with both RJ11 and RJ45 connections who want more than a basic cable check. Its cable functions cover Cat5/6 length measurement, physical-status testing for STP and UTP LAN cable, and detection of the crimping condition at the crystal head. PoE testing identifies the pins providing power, measures voltage, and identifies the PSE type across the stated at/af standards.
Those functions make the model relevant to mixed network-cable work, especially when cable condition and powered Ethernet connections are part of the same task. The product title's LAN Ethernet focus also keeps the main use case clear even though the tool extends into optical checks.
What stands out
The optical side gives the NF-8508 a role beyond copper-cable diagnostics. Its optical power meter has a stated test range of -70 dBm to +10 dBm. The visual fault locator uses a 10 mW red-light source for checking fiber breaks and damage. Together, these functions give the model a way to address optical power and visible fault-location tasks alongside network cable testing.
Meaningful trade-offs
The broad function set is also the key limitation. A shopper whose routine is confined to RJ11/RJ45 cable checks may not use the optical power meter or visual fault locator. Conversely, the NF-8508 is presented as a combined LAN-and-optical instrument, so its appeal depends on wanting those roles together rather than a narrowly focused cable-testing tool.

Reason to choose: The 9-in-1 design is the strongest fit signal for a shopper who wants one tool to cover several diagnostic tasks rather than a cable-only role.
Limitation: That same breadth can be unnecessary for a narrow RJ11/RJ45 testing routine, where the optical functions may go unused.
Bottom line
NOYAFA NF-8508 is a sensible choice when your RF network cable telecom test work spans Ethernet diagnostics and optical fault or power checks. Its main buying trade-off is straightforward: the USD 68.95 price is attached to a broad 9-in-1 scope, so the model is easiest to justify when you expect to use more than one part of that scope. For a narrow cable-testing job, consider whether the additional diagnostic functions belong in your regular work.
