Description
- An Attenuated Patch Cord is designed to attenuate an optical signal, usually to keep the detectors response in the linear region.A patch cord with fixed built-in attenuation is a cost-effective alternative to an attenuated adapter. A disadvantage with anextra adapter is that some reflection loss is introduced into the system. However, this problem can be avoided with an attenuated patch cord.
- GH high performance attenuated patch cords can be installed in place of conventional patch cords to provide a constant level of attenuation with more than 50DB return loss, they are compact, multipurpose passive devices designed to operate in 1310nm and 1550nm wavelengths.
- Attenuated Patch Cord can be provided with several different connectors styles with lengths up to 20 meters to meet varied customer requirements.
Features
- Combines the functions of an attenuator and a cable assembly
- Low back reflection
- SM or MM available
- Conforms to EIA/TIA standards
- Inexpensive compared to other type of attenuator
Applications
- Telecommunication Networks
- Data Networks
- Video&CATV
- Broadband
- FTTP
