The 6337D is a dual-channel modular optical power meter supporting simultaneous measurement with two power-meter modules. The optional 74601A-1133 and 74601A-1132 InGaAs modules cover 800–1700 nm, with power ranges of −90 to +10 dBm and −50 to +26 dBm respectively under CW operation at 1000–1630 nm. LAN, RS232C and USB interfaces support testing and calibration of optical communication components, fiber cables and optical sources.

Configuration and operating notes
- ¹ Module power ranges apply to continuous-wave (CW) input at 1000–1630 nm, not automatically to the entire 800–1700 nm band.
- ² Linearity conditions: CW, −60 to +10 dBm, 1000–1630 nm. These values do not cover the entire power range.
- Other calibration wavelengths can be configured on request. Set the measurement wavelength to match the center wavelength of the optical source.
- The product photograph illustrates a mainframe with installed modules. Power-meter modules are optional; confirm models, quantity and lead time when requesting a quotation.
- Specify the wavelength, power range, fiber type, number of modules, communication interface and application when requesting a quotation.
