FAQs

Q: What applications suit a 70 km CWDM SFP?
A: Long-haul metro access, inter-campus links, and backhaul where extended reach and fiber efficiency are required.

Q: Can I mix this with other CWDM wavelengths?
A: Yes. Use with a CWDM MUX/DEMUX, ensuring each transceiver uses a unique wavelength channel.

Q: Is this transceiver vendor-locked?
A: It is Cisco-coded. It operates in devices that accept Cisco-coded SFPs; verify your platform’s policy.

Q: Does it support digital diagnostics?
A: Yes, DOM/DDM is available when supported by the host device.

Q: What fiber type should I use for 70 km?
A: OS2 single-mode fiber with low attenuation and proper patching to meet the link budget.
