Features of OMK-SR-OTS.2
- Fully complete "turnkey" set – no need to purchase a light source or meter separately.
- Designed for HMA connectors (commonly used in military/tactical environments) – specialized HMA-FC and HMA-HMA adapters.
- High level of case protection (IP67, shock-resistant case) allows operation in field and harsh conditions.
- AWD (automatic wavelength selection) minimizes operator errors.
- USB interface for data transfer to PC allows report generation and documentation.
- Suitable for both installation and maintenance of fiber-optic networks.
Advantages
- Versatility: covers a wide range of wavelengths, interchangeable adapters, compatibility with various connectors.
- Compactness and mobility: the entire set fits in a case – convenient for field trips.
- Reliability: climate/shock-resistant case, field-ready.
- Convenience features: AWD, USB connection, data recording.
- Specialization for HMA / FC – an advantage for specific applications (military, tactical networks).

FAQ (Frequently Asked Questions)
Q1: Which networks is this set suitable for?
A: It is suitable for fiber-optic networks (both multimode and single-mode), especially when HMA connectors are used and field diagnostics are required.
Q2: Can losses be measured on two wavelengths simultaneously?
A: Yes – the LS-800 source supports multiple wavelengths (e.g., 1310 nm and 1550 nm) and has AWD function, making measurement easier.
Q3: Can a computer be connected for report generation?
A: Yes – the PM-800 meter has a USB interface, data recording, and compatibility with SmartProtocol software.
Q4: What warranty or service is provided?
A: The manufacturer states that the company is ISO 9001 certified and has an accredited calibration laboratory.
Q5: Is separate calibration required?
A: Yes – for accurate measurements, ensure devices have a current traceable calibration certificate. The set also includes accessories for connector cleaning.
Q6: Can it be used for a home FTTH network?
A: Technically yes, but the set may be excessive in functionality and cost. If the network uses standard connectors (LC/SC) and is low-demand, a simpler tester can be chosen.
