Miniature Singlemode Coupler
FOCI's Miniature Singlemode Couplers are ultra reliable devices featuring low backreflection, low insertion loss, and high port isolation over a wide range of temperatures and wavelengths. The Miniature Singlemode Couplers are designed to divide and/or combine different optical signals in optical fiber systems. With its innovative Fused Biconical Taper (FBT) process, FOCI's C-MS series Miniature Singlemode Couplers have proven to provide exceptional characteristics for all applications demanding critical performance. Splitting ratio can be customer specified between 1%:99% and 50%:50%. Available in a wide variety of packaging configurations, these C-MS series are operable in either 1310nm or 1550nm wavelength range. Various types of pigtailing and connector termination are available to meet your requirements.
- The packaging option codes are explained in packaging dimensions below.
- Low insertion loss.
- High port isolation.
- Environmentally stable.
- Custom defined specifications.
