Information - Questions? Call Ask for Chip or Trip The MT9812B is a mainframe supporting devices such as DFBLD multiple light sources and multi-channel device evaluation systems. A maximum of 9 MT9810B compatible light sources (DFB-LD, FP-LD, SLD) and optical sensor units can be inserted. In addition to being able to set and verify setting conditions for each unit on the front panel, a remotely controlled measurement system can be supported as GPIB and RS-232C interfaces are standard equipment. The unit incorporates a DFB-LD light source that supports D-WDM and complies with ITU-T. High Power of +10 dBm and high stability of better than or equal to ±0.005 dB are provided. In addition, high stability of better than or equal to ±2 GHz can be achieved for the center frequency. The center frequency of the light source can be varied in the maximum range of ±60 GHz (approx. ±0.5 nm). Moreover, the frequency can be displayed in either frequency or wavelength units. This function allows a required frequency to be set between reference grids. This system has the following modules installed: The cards have the following specifications: * Applicable optical fiber: SM (ITU-T G.652) * Specified wavelength: 1563.86 to 1530.33 nm (191.7 to 195.9 THz) * Center optical frequency: fp ±0.01 THz (approx. ±0.08 nm) * Spectrum half width: =30 MHz * Optical output power: +10 ±1 dBm * Time stability (short term): =±0.005 dB * Time stability (long term): =±0.02 dB * Temperature stability: =±0.25 dB * Center frequency stability * Time stability (short term): =±2 GHz (approx. ±0.02 nm) * Time stability (long term): =±4 GHz (approx. ±0.04 nm) * Tuning range: fp ±60 GHz (approx. ±0.48 nm), Step: 1 GHz (approx. 0.01 nm) * Accuracy: =±10 GHz (setting to fp +60 GHz, or fp –60 GHz, 25°C) * Frequency: 270 Hz, 1 kHz, 2 kHz ±0.1% * Duty: 50% ±5%, Extinction ratio: =13 dB * Optical output attenuation: 0.00 to 6.00 dB (0.01 dB steps), accuracy: =±0.5 dB (at 25°C when set to 6.00 dB) * Warm-up time: 1 h (after optical output on) Reasonable offers will be considered. This item is in excellent condition, working perfectly, and comes with a 14 Day Guarantee Against DOA. If you have any questions, e-mail me. |
