It scans the full C-band wavelength range between 1260 and 1650 nm for commissioning, upgrade, and trouble shooting of DWDM networks. The Nano-OSA offers the functionality and speed of an optical...
  • Page 6 Introduction SFP Slots The Nano-OSA offers 1 integrated SFP slot for mounting one SFP transceiver module or tunable laser (to be ordered separately). These SFP+ modules can be used as a DWDM stimulus to check DWDM networks together with the DWDM analyzer. An activated transceiver module connected to the SFP+ slot emits optical radiation at the output “TX”.
