How Often Should Fiber Tools (FSM, OTDR, and Power Meter) Be Serviced?
In fiber optic networks, the accuracy of installation, testing and fiber tool maintenance is critical. Equipment such as Fusion Splicing Machines (FSM), Optical Time Domain Reflectometers (OTDR), and Optical Power Meters must be serviced regularly to maintain performance and ensure reliable network results.
At Sangken Technologies, proper fiber tool maintenance is an essential part of delivering high-quality fiber installations and testing services.
🔧 Fusion Splicing Machine (FSM)
A fusion splicing machine precisely joins two optical fibers. Over time, electrodes wear out and dust can affect alignment, leading to higher splice loss.
Recommended Service Interval:
- Every 6 months
- Or after 3,000–4,500 splices (whichever comes first)
Maintenance includes:
- Cleaning fiber holders, mirrors, and V-grooves
- Replacing electrodes if required
- Performing arc calibration and alignment checks
- Inspecting heater and splice protection systems
Regular servicing ensures consistent low-loss splicing and reliable fiber connections.

📡 Optical Time Domain Reflectometer (OTDR)
An OTDR is used to measure fiber length, identify faults, and evaluate splice loss along a fiber link. Accurate calibration is essential for reliable measurements.
Recommended Service Interval:
- Once every 6-12 months
Maintenance includes:
- Connector and port inspection and cleaning
- Calibration verification
- Firmware updates and internal diagnostics
Routine servicing ensures accurate fault detection and network certification.
OTDRs:
🔎 Optical Power Meter
An optical power meter measures the light level in a fiber link and helps verify whether a network meets required power budgets.
Recommended Service Interval:
- Every 12 months
Maintenance includes:
- Sensor calibration
- Connector inspection and cleaning
- Accuracy verification using reference sources
Proper servicing ensures precise power measurements and reliable link validation.
