Isolating Wavelength Division Multiplexer
- Combines a high-power multimode pump and a single-mode signal to a single SMM900 dual clad pump-signal fiber output
- Designed for cladding-pump applications with CP1500Y
- Provides multiplexing and isolation in one small package
Typical Applications:
- High power Erbium Doped Fiber Amplifiers (EDFAs)
- Fiber lasers
- WDM systems
- Cable Television (CATV)
