WDM fronthaul assigns each link its own wavelength, while passive fronthaul shares one wavelength through optical splitters.

CWDM Fronthaul vs DWDM Fronthaul

By C-LIGHT Marketing 丨 Mar 20, 2026

CWDM and DWDM fronthaul both multiplex multiple 5G radio links onto shared fiber, but differ in channel count, wavelength spacing, laser type, power budget, cost, and reach. Compare deployment scenarios for 5G transport.

FTTH vs FTTR

By C-LIGHT Marketing 丨 Mar 19, 2026

FTTH and FTTR both deliver fiber to the premises, but they differ in where optical conversion happens. Compare architecture, bandwidth, latency, coverage, deployment cost, and application scenarios for home and business networks.

FTTH vs FTTB

By C-LIGHT Marketing 丨 Mar 18, 2026

FTTH and FTTB both use fiber in the access network, but they differ in where the fiber ends and how the signal reaches the subscriber.

FTTB vs FTTC

By C-LIGHT Marketing 丨 Mar 17, 2026

FTTB and FTTC both use fiber in the access network but terminate it at different points. Compare copper loop length, achievable bandwidth, cabinet vs building deployment, power, cost, and upgrade paths to full FTTH.

FTTC vs FTTN

By C-LIGHT Marketing 丨 Mar 16, 2026

FTTC and FTTN both extend fiber into the access network but terminate it at different distances from the subscriber. Compare copper loop length, achievable bandwidth, cabinet vs node deployment, cost, and upgrade paths to FTTH.

FTTH vs FTTN

By C-LIGHT Marketing 丨 Mar 15, 2026

FTTH and FTTN represent opposite ends of the fiber access spectrum. Compare fiber-to-the-home and fiber-to-the-node architecture, copper loop length, achievable bandwidth, latency, deployment cost, and the migration path to full fiber.

FTTO vs FTTH

By C-LIGHT Marketing 丨 Mar 14, 2026

TTO and FTTH both deliver fiber to the end user, but one is a dedicated point-to-point business connection and the other is a shared residential PON.
