Mode-hop free performance across the band

under nominal conditions. When operating

with the wavelength reference, even if the

laser does mode-hop, the TLS will detect and

correct for this anomaly, which can occur with

any laser under some conditions

Wavelength resolution of 0.08pm

to precisely characterize narrow

band DWDM components

Continuous sweep at 1–1000 nm/second; with a typical sweep of 100

nm/sec, characterization of full C+L band components in less than 1

second. If desired, the laser can be slowed to any speed between

1 and 1000 nm/second.

Output power of +3 to -3 dBm with low noise gives

sufficient power with the CSA or Swept

Spectrometer to characterize even the deepest

components—even with the TLS power

split to several test benches. The High power

version provides +8 dBm

Output power is very stable. When used with the

dBm power reference option, any uncertainty due

to output power variation is eliminated.

The Wavelength Reference Option brings

accuracy to between 1 pm and 5 pm.

Without the Wavelength Reference

Option, accuracy is still 30 pm

in both stepping and continuous sweep

modes.

Easy to use from the front panel,

ethernet or GPIB
