Fused WDM
Fused WDM combines light sources and emits at different wavelength into an optical fiber. They are manufactured using fused biconical taper (FBT) process. Our fused WDMS series are ultra reliable devices featuring high isolation, low insertion loss, and high port isolation over wide ranges of temperature and wavelength. LFO fused WDM series have proven to provide exceptional characteristics for all applications demanding critical performance.
Following are three types of the fused WDMS devices we provide:
1. Standard singlemode WDMS
These devices are designed to divide and / or combine different optical wavelength in optical fiber system. They are operable in 1310nm / 1550nm, 1310nm / 1650nm, or 1550nm / 1650nm wavelength ranges.
2. High isolation WDMS
These devices are designed to divide and / or combine different optical wavelength in optical amplifiers. They are operable in 1310nm / 1550nm, 1310nm / 1650nm or 1550nm / 1650nm wavelength ranges.
High isolation WDMS provide channel isolation higher than 30dB, compared to the Standard singlemode WDMS.
3. Pump WDMS
These devices are designed to divide and / or combine different optical wavelength in optical amplifiers. They are operable in 980nm / 1550nm, 1480nm / 1550nm wavelength ranges.
Various types of pigtail and connector terminations are available to meet your requirements. Available in a wide variety of packaging configurations.
