Integrated Tunable Laser Assembly

The FLS-2800 is a benchtop, continuous wave (CW), tunable laser with a high-power output, narrow 100 kHz linewidth and 10 pm resolution tunability over the C or L band. This laser offers a cost-effective and versatile solution for various applications, including coherent/orthogonal frequency-division multiplexing (OFDM) transmission and WDM network emulation. The FLS-2800 is available in single- or dual-laser configurations.

Ease of Use

Local Control

The FLS-2800 is easy to directly control using the knob on the front panel. Each laser is controlled separately, and both wavelength and power can be adjusted quickly and precisely.

Remote Control

Using the EXFO TLM application, which is also fully compatible with the IQS-2800, it is possible to control the FLS-2800 remotely via the USB or Ethernet ports at the back of the unit. SCPI commands are also available when automation is required. The EXFO TLM user interface makes it very easy to view the status and control the lasers.

In the last 12 months, we have seen multiple trials for 200G and 400G transmission worldwide on both client and line sides, which have presented multiple challenges. At this moment, new technologies and standards are being developed by groups, such as ITU, IEC, OIF, IEEE, to meet beyond 100G network requirements.  This webinar will review the potential technologies enabling transmission beyond 100G and the expected challenges related to deployment and testing, with a particular focus on long-haul and metro requirements.
