Keysight (Agilent) 81662A DFB Laser Source Module

The Agilent 81662A Distributed Feedback (DFB) Laser Source module provides +10dBm output power to overcome the power penalties given in todays test setups. It's excellent stability in power and wavelength is key for accurate testing of any kind of optical amplifiers, such as EDFA, TDFA, semiconductor and Raman amplifiers. Specifications. Maximum output: Typical > +10 dBm (10 mW). CW stability (24 hours): Typical ±0.03 dB. Wavelength (original model): ITU Grid (100 GHz) ie: 1,529.55 nm (opt. 309); 1,610.06 nm (opt. 505) or Center wavelength: (opt. 131) 1310 nm ± 5 nm, (opt. 149) 1490 nm ± 3 nm, (opt. 151) 1510 nm ± 3 nm, (opt. 155) 1550 nm ± 3 nm, (opt. 162) 1625 nm ± 3 nm. Tuning range: Typical > ± 500 pm. Display resolution: 10 pm. Repeatability: ± 3 pm (typical ± 1 pm). Stability (15 minutes): ± 3 pm (typical ± 1 pm). Fiber type: Panda PMF 9 / 125 µm. Output connector: Compatible to angled contact APC, ASC, DIN47256/4108. Side mode suppression ratio (SMSR): Typical 45 dB. Internal digital modulation mode: Free selection 200 Hz to 100 kHz, all output signals are pulse shaped duty cycle 50%. Internal coherence control for linewidth broadening. Tuning speed over full range 30 s.

*This is a Web introductory price for one calibration of the Keysight (Agilent) 81662A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Broadband Source (BBS)
A Broadband Source is a spectrally large source that emits a signal which contains a continuous range of frequencies with a broad optical bandwidth (usually 100 nm or more). Sometimes called a white light source, there are two different meanings of this term. Visible white light and a source which does not necessarily emit in the visible spectral region.

Coherence
Coherence is the pattern and or relationships of waves due to phase properties.

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Power Flatness Over Modulation
When changing the wavelength and modulation frequency, and measuring the differences between actual and displayed power levels (in dB), the power flatness is ± half the span between the maximum and the minimum value of all differences.

Singlemode fiber
Singlemode Fiber has a small core, only about 9 microns, and is used for telephony and CATV with laser sources at 1300 and 1550 nm. It can go very long distances at very high speeds. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.
