Hello, can I use your FS BOX to program the transceiver?

by W***a on 12/20/2024

Yes, you can use the FS BOX to program FS transceivers. It supports functions like online configuration, diagnostics, and wavelength tuning for tunable transceivers. However, it does not support reconfiguring certain modules like HPE compatible transceivers or 40G BiDi transceivers currently.

Hi, I need WSP-Q40GLR4L cisco, should I choose #36172 or #48276?

Hello, the my link distance is around 150M, if buying QSFP-LR4L-40G 2KM single-mode module to transmit 150M will cause damage to the module/equipment, the whole link? Thank you.
