Product Manual
Features
- Cascadeable, bi-directional eight channel mux/demux modules
- ITU-T G.694.1 compliant 0.8nm (100GHz) channel spacing
- Capable of being inserted into CWDM 1550nm wavelength slot adding an additional 8 or 16 DWDM wavelengths to existing CWDM systems
- Passive design for any bit rate
- Low insertion loss to conserve system power
- High optical isolation for low crosstalk
- Fully hot swappable from front of frame with no fiber disconnect/reconnect required
- SC/PC, ST/PC*, FC/PC* connector options
- Fiber protector to prevent connector damage
* 7705DWDM to be used ONLY in Single Mode Fiber applications
Applications
