Fibtele project input brief
Solution: CWDM & DWDM Network Planning by Channel, Loss & Reach
Solution slug: cwdm-dwdm

Quick answer
Choose CWDM for wider channel spacing and simpler shorter links, or DWDM when channel count, spectral efficiency and amplified reach justify tighter control. Confirm wavelength plan, mux loss, transceivers, dispersion, power and monitoring before deployment.

Inputs required before selection
- Required channels, wavelengths and growth reserve
- Fiber type, route loss, reach and dispersion
- Mux/demux, OADM, amplifier and monitoring plan
- Transceiver grid, power budget and connector package
- Protection, service turn-up and acceptance policy

Selection checklist
- CWDM grid or DWDM ITU channel plan
- Channel count and upgrade reserve
- Mux/demux, OADM, rack, LGX or ABS package
- Line rate, reach, dispersion and power budget
- Monitoring, protection and commissioning documentation

Important limits
- Channel count alone does not determine capacity; optics, loss, dispersion and power also constrain the link.
- DWDM planning may require amplifier, dispersion and monitoring engineering.
- Confirm active equipment wavelength plan before ordering passive modules.

Ordering note
This planning brief is for project scoping. Confirm the exact products, interfaces, documents, quantity, MOQ and lead time in the written quotation before ordering.
