Optical Power Meter K-520

The slim meter of the range: the same two detector grades and eight PON wavelengths in a 26 mm body that disappears into a tool pouch.

Two detector grades: −70 to +6 dBm (A) or −50 to +26 dBm (B)
Eight calibrated wavelengths, including 1577 nm for XGS-PON
Slim 113 × 70 × 26 mm body, 150 g
Linear (nW) and logarithmic (dBm) readings on one screen
Wavelength memory, user calibration and user zeroing
Dry-cell or rechargeable Li-ion versions
SC / FC / ST interfaces; auto power-off after 10 minutes

K-520 or K-510?

Both meters measure the same way. The K-520 is the slimmer body for pouch carry; the K-510 adds the high-brightness LED work light and low-light mode for cabinet work. Detector grade and power source are chosen the same way on both.
