1×2 FSW OSW 850NM
The 1×2 FSW OSW 850nm is a compact and cost-effective 1×2 fiber optic switch designed for reliable optical signal routing and network protection at 850nm wavelength. Featuring low insertion loss (0.5 dB typical), high channel isolation, and an epoxy-free optical path, it ensures high stability and long-term performance. This latching or non-latching switch supports multimode fiber applications and is widely used in optical network protection/restoration, signal routing, configurable optical add/drop, and transmitter/receiver protection. With a power supply option of 3.0V or 5.0V, operating temperature range of -20°C to +75°C, and multiple connector and fiber length options, it offers flexible integration for various optical test and communication systems.

| Description of indicator status: | 
| PWR: Module power status. When the light is on, it indicates normal power supply; when the light is off, it indicates abnormal power supply. | 
| RUN: Module working status. When it flashes, it indicates the module is working normally; otherwise, it is abnormal. | 
| Pri: Optical path channel status. When the light is on, it indicates the channel is In1→Out; | 
| Sec: Optical path channel status. When the light is on, it indicates the channel is In2→Out; |
