OLA-54/OLA-55 Optical Attenuator
Other Products
- The OLA-54 SMTQ Optical Power Attenuator is designed for multimode fiber systems (50/125μm fiber).
- The OLA-55 SMTQ Optical Power Attenuator is an instrument that meets future development needs, used for system testing, installation, maintenance, and single-mode fiber production. Due to its Differential Group Delay (DGD), the OLA-55 is also suitable for 40G transmission systems.
A new member of the series. Used for system testing, installation, and maintenance. Features low Differential Group Delay (DGD). Additionally, the OLA-55M is also suitable for 40G transmission systems.
