Product Description

High Isolation Polarization-Maintaining Taper Short WDM for Erbium-Doped Amplifiers

Product Description

Shortwave wavelength division multiplexing (SWDM) is a technology that uses multiple wavelengths at the shorterwavelength end of the fiber optic spectrum, around 850nm, in a single multimode fiber (MMF). in other words, the samewell know CWDM technology is applied to short reach MMF systems.

SWDM systems use four channels centered at 850, 880, 910 and 940nm (30nm spacing) to achieve higher data rates.

40Gbps is implemented as 10Gbps x 4λ and 100Gbps is implemented as 25Gbps x 4λ.
