Description of model 83437A
The Agilent 83437A Broadband Light Source (BBLS) is based on Agilent Technologies’ edge-emitting LED (EELED) technology. An EELED provides significantly more power density into a single-mode fiber than a regular LED and more than one hundred times that of a white light source.
The 83437A can incorporate up to four EELEDs, with five available wavelengths in the 1200 to 1650 nm range. Connectors on the back panel allow you to modulate the light by applying a TTL compatible signal, or to selectively turn any of the EELEDs on (open connection) or off (shorted). In configurations with multiple EELEDs installed, optical couplers combine the light to a single output.
In order to minimize coupler losses, Agilent uses wavelength-dependent and wavelength-independent couplers depending on the ordered configuration.
Peak wavelengths: 1200 ±30 nm / > -17 dBm, 1310 ±20 nm / > -13 dBm, 1430 ±30 nm / > -13 dBm, 1550 ±20 nm / > -13 dBm, and 1650 ±30 nm / > -17 dBm.
Compatible fiber: 9/125 µm, single mode.
Output return loss(Characteristic value): > 25 dB ( 50 dB ).
Power stability (1310 / 1430 / 1550): < ±0.02 dB (15 min), < ±0.05 dB (6 hr).
Power stability (1200 / 1650): < ±0.03 dB (15 min), < ±0.05 dB (6 hr). Modulation: Digital (TTL compatible input), 100% on-off, DC to 100 kHz).
