| Criteria | OTDR | Optical Power Meter | Fiber Inspection Probe |
|---|---|---|---|
| Fault Location | Yes — pinpoints faults to ≤ 1 m accuracy | No — measures total link loss only | No — visual endface inspection only |
| Test Speed | 10–180 seconds per trace | Instant (< 2 seconds) | 3–8 seconds per connector |
| Typical Cost Range | $4,000–$25,000 | $300–$2,000 | $1,500–$6,000 |
| Best For | Installation certification, fault diagnosis, long-haul links | Daily spot checks, simple pass/fail verification | Connector quality assurance, contamination detection |
| Key Limitation | Dead zone prevents short-link testing (< 100 m) | Cannot identify fault location or type | Only inspects connector endface, not fiber span |
