N7779C Step-Tunable Laser Source, High Power and Low SSE, Basic Line
The new N7779C basic line step-tunable laser source is ideal for cost-effective testing of broadband optical devices. It can also serve as a highly stable, tunable local oscillator for receiver testing or transmission experiments.
Starting from
Highlights
- Wavelength: 1240-1380 nm or 1340-1495 nm or 1450-1650 nm or 1490-1640 nm
- Tuning time: 300 ms for a 1 nm step
- Max. power: > +12 dBm peak typ. (Options 114, 116, 216) or > +13 dBm peak typ. (Option 113)
- Signal to SSE ratio: ≥ 75 dB/nm typical
- Absolute wavelength accuracy: ±10 pm typical
The new N7779C basic line tunable laser source, like the other new N777xC models, can step quickly to discrete wavelengths with a resolution of 0.1 pm and a typical wavelength repeatability of ±3 pm, making it ideal for cost-effective testing of broadband optical devices. With wavelength setting times like 300 ms, rapid stepped sweeps are possible. Like the other lasers in the N777xC family, it delivers more than +12 dBm peak output power with low spontaneous emission levels. At ±0.01 dB power stability over an hour, it can also serve as a static local oscillator with a wide tuning range for receiver testing or transmission experiments.
The wavelength tuning performance has been enhanced to provide default fine tuning without overshoot. No separate fine-tuning control is needed for smooth tuning with 0.1 pm resolution, due to automatic coordination of the motor and piezoelectric-actuator. This simplifies wavelength-optimization procedures.
All N777xC tunable lasers are based on a common cavity and laser module design and share a narrow linewidth, excellent long-term stability and low spontaneous emission level. They are software compatible with the 8160xA and 81600B lasers, the industry standards for more than a decade, but occupy 1 height unit less rack space. The remote user interface on the instrument is accessible with just a web browser, either via LAN or via USB connection. An optional touch-screen display provides local operator access and displays current operating parameters.
