  • Hand-held, rugged, lightweight
  • Test single-mode and multimode networks
  • Auto-detect transmitted wavelength (reduces errors)
  • Test two wavelengths simultaneously (faster testing)


  • Certify multimode and single-mode links per TIA/EIA standards
  • Fiber identification prior to splicing
  • Passive Optical Networks (PON) testing

Single-Mode and multimode Loss Test Kit with Wave ID and Set Reference

NOYES SMLP4-4 rugged loss test kit for testing and certifying fiber networks to industry standards. Backlight display works well in darker environments or direct sunlight.  Interchangeable connector adapters provide access to common network interfaces and provide access for cleaning launch and receive ports.   

OLS4 Quad Source is an integrated two-port LED (850 and 1300 nm) and LASER (1310 and 1550 nm) light source designed for performing insertion loss measurements on multimode or single-mode fiber optic links. Each port can transmit highly stabilized output (single or dual wavelength) ensuring accurate test results per current TIA/EIA requirements.  Equipped with industry standard 2 kHz test tone, the OLS4 from AFL is an ideal tool to pair with an optical fiber identifier (OFI-200D) for use in fiber identification.

OPM4-2D Optical Power Meter provides accurate measurements, reference storage for each calibrated wavelength, offers multiple test tone detection for fiber identification.   Set-Ref feature allows the OPM4 to display measured power levels above a known measured level.

Automatic wavelength identification significantly increases efficiency

Standard Wave ID feature automatically detects and sets the receive wavelength(s), preventing setup and measurement errors.  It significantly increases efficiency and reduces technician errors—and saves testing time—by eliminating the need to test each wavelength individually.

Optical References Storage

The OPM4 stores optical references for each calibrated wavelength and offers multiple test tone detection for fiber identification.

50 and 62.5 µm Fiber Mandrels Included

Mandrels condition test cable for use in certifying both 50 and 62.5 µm fiber links for current and planned high bit rate applications including Gigabit Ethernet and 10 Gigabit Ethernet.  Mandrels apply to launch jumpers is seconds without tools and ensure loss measurements comply with TIA/EIA-568-B standard.
