Call Ask for Chip or Trip The larger transmission capacity required by multimedia applications has seen increasing use of wavelength division multiplexing (WDM) using optical fiber amplifiers in every field from R&D to commercial operation. As a consequence, key WDM optical devices such as optical fiber amplifiers, couplers, and isolators require even higher performance and stability. The MG9637A design meets these requirements through excellent wavelength repeatability achieved by self calibration, improved reliability using a new external cavity technology. The MG9637A utilizes an external optical automatic power control (APC) module, and has a Lithium Niobate modulator in the APC section to provide excellent output power stability and S/N ratio. It is ideal for evaluating the wavelength loss characteristics and polarization mode dispersion (PMD) of optical devices (couplers, filters, etc.), as well as the gain and noise figure of optical fiber amplifiers and PMD used in dense wavelength division multiplexing (DWDM) system. This system has the following features: * 1 pm wavelength setting resolution * +/- 7 pm max. wavelength repeatability This unit has the following specifications: * Wavelength range: 1500 to 1580 nm * Wavelength setting resolution: 1 pm * Absolute wavelength accuracy: < +/- 0.1 nm * Wavelength stability: < +/- 100 MHz/h * Wavelength repeatability: +/- 35 pm (80 nm range), Typical: +/- 7 pm (at +/- 3 nm, after calibration) * Side mode suppression ratio: > 45 dB (1520 to 1570 nm); > 40 dB (1500 to 1580 nm) * Linewidth (typical value): 700 kHz (coherent control: Off), 50 MHz (coherent control: On) * Wavelength switching time (typical value): 100 ms/1 nm, 150 ms/10 nm, 500 ms/80 nm * Max Output Power: >–10 dBm (1520 to 1570 nm); >–13 dBm (1500 to 1580 nm) * Min. setting output power: <–20 dBm * Power stability: < +/- 0.01 dB/h * Power flatness: < +/- 0.1 dB * Polarization extinction ratio: > 18 dB * Output 2 Output power: > – 10 dBm * Internal modulation: 200 Hz to 20 kHz (square waveform), Duty: 50% * External modulation: 1 MHz to 3 GHz * Main functions: Wavelength calibration, single-step sweep * I/O Connector: Frequency control input, external modulation input, sweep signal output, sweep trigger signal output, internal modulation sync signal output This item is in excellent condition, working perfectly, and comes with a 14 Day Guarantee Against DOA.
