Frequently Asked Questions
Q: What's the function of this bypass fiber switch?
A: This product protects fiber paths. If the protected fiber switch loses power, the optical path automatically bypasses the failed switch and directly connects to the next fiber switch, ensuring network continuity when individual switches are powered off.
Q: Does it include the power supply?
A: No, power adapter is not included and must be purchased separately. The input voltage range is 12V-52VDC.
Q: What temperature range can this device handle?
A: Operating temperature range is -20°C to 70°C (-4°F to 158°F).
Q: Does it come with a small din rail?
A: The switch supports 35mm DIN rail mounting, but the DIN rail itself is not included.
Q: Is it a managed product?
A: No, this is an unmanaged product designed for automatic optical path protection.
