Pro8000 Modular laser platform sold by Thorlabs. Included is the programmable Chassis and 8 laser sources. We have three systems available. See: http:// /NewGroupPage9.cfm?ObjectGroup_ID=895&Visual_ID=2018 These units with the 8 DWDM laser sources retail at ~18k - 20k We are offering these at 50% list price. All units are fully tested and had little use. See our website for details on what wavelengths are available at Rack Mountable 8 Slot Version: PRO8000 Chassis for Large Test and Manufacturing Environments PRO8000-4 Chassis for High Power Applications Current and Temperature Controllers for Laser Diode Operation, Characterization, or Burn-in Applications Various Optical Modules including WDM Laser Sources and Optical Switches for Component Testing in Production and Quality Control Remote Control via IEEE 488.2 and RS232 with Drivers for LabVIEW™and LabWindows/CVI™ The PRO8 display menu allows easy configuration of any module in the chassis. Mneumonic symbols provide user-friendly access to all operational parameters. All settings are retained in memory and automatically recalled upon powering on the mainframe, as long as modules are not moved to different slots during power down. Individual modules are automatically identified and, when selected, can be configured and controlled using the softkeys. ************************************************** * DWDM DFB Laser Sources for ITU Wavelengths (down to 25GHz spacing) * DWDM: Complete Coverage of ITU Wavelengths within ITU Grid (S, L and C Band) (See Order Lines below) * Output Power: 10mW (CWDM), 20mW (DWDM) * Unbeatable Wavelength Stability (typ. < 2 pm/24hrs) * Extremely Stable Output Power < 0.01dB/24hrs * Precise Wavelength Tuning over ± 1nm (CWDM: ±0.5 nm) * Direct Display of Wavelength During Tuning * Precise Power Attenuation over 10dB * Variable Coherence Control, Linewidths Adjustable up to 1GHz * Instrument Drivers for LabVIEW™ & LabWindows/CVI™ The PRO8 WDM Laser Modules are DFB laser sources for the PRO8 Test & Measurement Platform with precise tunability, long term wavelength and power stability, and adjustable coherence control. For detailed information about the PRO8 test and measurement platform, please see PRO8 Platform. If you need a complete system with 8 laser sources, please see Preconfigured Laser Banks. The PRO8 CWDM DFB Laser Modules are available with center wavelength intervals of 20nm in the range of 1470nm to 1610nm, i.e. 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610nm packaged as plug-in modules for a PRO8 chassis. A TEC cooler integrated with each laser stabilizes the wavelength to better than ± 0.002nm (24hrs). The PRO8 DWDM DFB Laser Modules are available for center wavelengths within the ITU grid for S, C, and L Bands. Other wavelengths are available on request; these modules are ideal for both active and passive DWDM component testing, and multi-wavelength transmission experiments. Precise Wavelength Calibration and Control All of the PRO8 laser modules utilize telecom rated DFB laser diodes housed in butterfly packages. Each laser diode contains an integrated TEC and a temperature sensor to ensure long term stability of the laser. Using the front panel controls of the PRO8 chassis the wavelength of each DWDM module can be tuned by ±1nm (approximately ±125GHz) at constant output power. This is accomplished through the use of a comprehensive factory calibration (wavelength dependence on both the temperature and the injection current) of each laser source. Stability, Accuracy, and Dependability With laser linewidths of less than 10MHz, center wavelength stability of better than 0.002nm per 24 hours, and wavelength accuracy of typically ± 10pm, the PRO8 DWDM laser sources are an ideal choice for demanding DWDM test and measurement applications. We use only telecom rated, butterfly packaged DFB laser sources with integrated TEC elements, optical isolators, and low backreflection fiber pigtails. When combined with our sophisticated drive circuits the result is an extremely stable, low noise laser source witnessed by optical power stability better than 0.002 dB per 15 minutes, a Side Mode Suppression Ratio of better than 45dB (typ.) and a Relative Intensity Noise (RIN) figure of less than -145 dB/Hz. The ITU-T DWDM Grid contains 600 wavelengths (25 GHz channels) spanning the S, C, and L-bands. Thorlabs stocks a comprehensive inventory of C- and L-band lasers with powers of 10mW (CWDM) and 20mW (DWDM). Coherence Control, Internal Modulation All of the DWDM Series laser modules provide an adjustable coherence control. This reduces impacts on fiber transmission due to Stimulated Brillouin Scattering (SBS). SBS can lead to significant errors when making optical power measurements in fiber based systems. The magnitude of the error can be reduced by increasing the linewidth of the source. A small signal modulation on the laser current is used to broaden the DFB laser linewidth from about few MHz to more than 1GHz. The PRO8 provides continuous adjustment of the linewidth over this entire range by means of an internal noise source or an internal waveform generator (sine / square / optional triangle). The waveform generator can modulate the laser power between 20Hz and 50kHz. External Modulation, DC to 10kHz All laser modules within a chassis can be controlled (switch on/off) simultaneously by an external TTL level signal (DC to 10kHz), applied to a BNC input on the back panel of the chassis. The wavelength is displayed on the PRO8 front panel or read through the IEEE 488 interface with a resolution of 0.001nm. By precisely controlling the temperature and injection current of the laser chip, the emitted wavelength can be tuned over a range of ±1nm (approx. ±125GHz, i.e. more than one ITU 100GHz channel) while output power remains stable. This feature is useful for simulating crosstalk between channels. It can also be used to measure the profile of narrow band DWDM filters. (this posting is the responsibility of the poster) |
