OP-970-EU(Extension kit for basic fibre optic communications training system)
Upgrades the basic Fibre Optics Trainer (EF-970) to the same characteristics as the EF-970-E
Photo-emitter 1300 nm Led
1 mm InGaAs PIN photo-detector
0.1 mm Ge APD (variable internal gain photo-detector)
The EF-970 Fibre Optic Communications Training System is a simplified version of the EF-970-E, including five photo-emitters and two photo-detectors. The rest of features are the same as those of the EF-970 E. If desired, the EF-970 can be upgraded to the EF-970 E with the OP-970-EU option.
