These series devices include several types:
- Wavelength Switch Device : It can provide date transmission between two wavelength, This kind of device also can be used as positive power enlarge device such as 1310nm↔1310nm、1310nm↔1550nm、1310nm↔850nm、850nm↔1550nm
- Mode Switch Device： It can provide date transmission between multi mode (850nm,1310nm)and single mode (1310nm,1550nm)，This kind of device also can be used as positive power enlarge device.
- Fiber Switch Device: It can provide the date transmission between single –fiber and dual–fiber.
- Switch different wavelength and two types of mode
