Will this LS-BL49551G-A6I module work directly with Cisco Catalyst switches without throwing any third-party optic warning errors?

Yes, absolutely! These modules are pre-coded with standard vendor compatibility. If you need specific OEM coding like Cisco, HP, or Juniper, you can request it during checkout, and they will program it before shipping so it runs completely error-free.

Is the industrial temperature rating (-40°C to 85°C) true for both ends, and does it require any special cleaning before installation?

Yes, the industrial rating covers the full harsh temperature range. As for installation, we always recommend standard optical cleaning with 99% isopropyl alcohol wipes and a fiber scope check before plugging in, just to prevent dust from degrading that 160km link budget!

Can I pair this 1490nm-TX/1550nm-RX module with a standard media converter on the remote end, or does it strictly need the matching inverse BiDi SFP?

You will need the matching inverse BiDi SFP on the remote end (which would be 1550nm-TX/1490nm-RX) because BiDi technology multiplexes different wavelengths over a single strand of single-mode fiber. A standard dual-fiber media converter won't match the wavelength pairing.
