Optical Modulators
The EOCV series Fiber Optical Transmitters (Electrical-to-Optical Converters) provide high-fidelity analog and digital optical signals from electrical inputs, supporting a wide frequency range of DC to 20 and 50 GHz. These user-friendly turnkey modules feature a corresponding Thin Film Lithium Niobate Fiberoptic Modulator (TLNM), a DFB laser with driver, an automatic bias controller, high-performance control circuits, and a DC power supply, all integrated into a convenient plug-and-play benchtop unit. The TLNM modulators employed in the EOCV series use smaller and shorter waveguides compared to conventional LiNbO₃ modulators, offering greater efficiency in converting RF signals into optical signals. Their low RF driving voltage eliminates the need for an external RF amplifier, making the system compatible with standard function generators for laboratory applications.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
20/40/50 GHz LN Fiber Optical Transmitter/Converter – Turnkey: Optical modulation depends on preserving the optical budget through the complete path. The C-Band, L-Band, 1550 nm, 1551.11 nm, 1562.22 nm, Tunable ITU Laser wavelength specification sets source and detector compatibility. The fiber/interface entry (FC/APC, FC/UPC, Special) must match the connected components. The 20GHz, 40GHz, 50GHz dynamic specification sets the usable control bandwidth.

Technical FAQ
Fiber Connector: FC/APC, FC/UPC, Special. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Laser Wavelength: C-Band, L-Band, 1550 nm, 1551.11 nm, 1562.22 nm, Tunable ITU Laser. Check the Optical Modulators passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
