1550nm Tapered Shortwave Wavelength Division Multiplexer SWDM
Short Wavelength Division Multiplexing (SWDM) is a technology that transmits data at high speeds and low costs by using multiple wavelengths in a single multimode fiber. SWDM is a cost-effective alternative to upgrading fiber infrastructure for higher data rates.
Here are some key features of SWDM:
-
Wavelengths
SWDM uses multiple wavelengths in the 850-950 nm range, which is optimized for multimode fiber.
-
Data rates
SWDM can transmit 40 Gigabit Ethernet (40G) or 100 Gigabit Ethernet (100G) over a single multimode fiber.
-
Cost
SWDM uses low-cost vertical-cavity surface emitting lasers (VCSELs).
-
Operational simplicity
SWDM has a simple Tx and Rx port, making it easy to tap for network security appliances.
-
Network monitoring
SWDM4 transceivers can be used with standard network taps and transceivers on monitoring equipment.
Features
- High lsolation
- High Return Loss
- Low Insertion Loss
- High Extinction Ratio
- High Stability & Reliability
Applications
- EDFA
- Research
