JGR Optics: TLS5 Tunable Laser Source

The TLS5 Tunable Laser Source (TLS5) offers an ultra-wide continuous wavelength range of 1260 to 1630 nm, all in one bench-top chassis. The TLS5 enables customers to span the entire CWDM spectral range at a relatively low cost, enabling affordable testing of CWDM as well as broadband optical components. Currently, an alternative approach would require the use of several tunable laser sources, each covering a different wavelength range, to achieve the same wide wavelength coverage. The cost of such an approach would be several times higher than that of the TLS5. To accomplish such wide wavelength coverage, the TLS5 uses several optical amplifiers and an external cavity.
