IMPORTANT
1. Please do not attempt to look into the optical connector with power applied, eye damage may result.
2. It is prohibited to touch the laser without any anti-static tool.
3. The optical input power should be only from -6 to +2dBm. The receiver may work when input power is
lower than -6dBm, but CNR will be largely deteriorated; when the input power is higher than 2dBm, CTB
and CSO will be deteriorated and may even cause the damage of the optical receiving module.
4. Clean the end of the connector with a lint free tissue moistened with alcohol before you insert the
connector into the receptacle of the SC/APC adapter.
5. This machine should be grounded before operation. The grounded resistence should be <4
Ω
6. Please carefully bend the fiber.
