Single-mode and multimode fiber testing with OTDR analysis, insertion loss measurement, and IEC 61300-3-35 connector inspection.
Fiber optic cabling delivers the bandwidth, distance capability, and electromagnetic immunity required for high-performance network infrastructure. From backbone connections spanning campus buildings to high-density data center interconnects, fiber installations require comprehensive certification.
Our fiber optic certification services cover the full spectrum of fiber types and test methodologies. We perform Tier 1 certification using calibrated light source and power meter equipment, Tier 2 certification using OTDR analysis, and connector end-face inspection.
Tier 2 Fiber Characterization
IEC 61300-3-35 Analysis
9µm core supporting transmission over kilometers. OS1 for indoor, OS2 for outdoor. Tested at 1310nm and 1550nm wavelengths.
Laser-optimized 50/125 with 2000 MHz·km bandwidth. Supports 10GBASE-SR to 300m and 40GBASE-SR4 to 100m.
Enhanced with 4700 MHz·km. Extends 10GBASE-SR to 400m and supports 100GBASE-SR4 to 100 meters.
Wideband multimode with optimized 953nm performance. Supports SWDM for increased capacity.
High-density multi-fiber interfaces supporting 8, 12, or 24 fibers for 40G and 100G parallel optics.
Standard single-fiber connector interfaces. Full inspection and certification for all types.
Tier 1 Testing uses a calibrated light source and power meter (LSPM) to measure total insertion loss and verify length. This validates that aggregate link loss falls within the budget.
Tier 2 Testing adds OTDR analysis to characterize individual events along the fiber path. The resulting trace shows location and loss of connectors, splices, and anomalies.
OTDR testing is valuable for troubleshooting, long-distance links, and high-value installations.
| Fiber Type | Wavelengths | Typical Loss |
|---|---|---|
| Single-Mode | 1310nm, 1550nm | 0.35 dB/km |
| Multimode (850nm) | 850nm, 1300nm | 3.5 dB/km |
| Connector (mated) | All | 0.2-0.5 dB |
| Fusion Splice | All | 0.05-0.1 dB |
Connector quality directly determines fiber link performance. Contamination, scratches, chips, and pits on connector end-faces increase insertion loss and reflectance.
We inspect every connector end-face using fiber inspection microscopes. Connectors are evaluated against IEC 61300-3-35 pass/fail criteria:
