Optical Bypass Switch

Optical Bypass Switch

The IBP-202 Optical Bypass Switch is an industrial grade external bypass switch for optical-node failure in fiber optical network infrastructures. The IBP-202 Optical Bypass Switch prevents and saves communication from network failures during power loss. When power failure occurs, the Bypass switch will swiftly set to bypass mode and isolate the main-network from the local networking device (See Figure 1). Bypass switches are commonly used in some major optical networks, such as in railway communication systems, factory automation, and power substation, where fiber link failures are not tolerated.

  • Supports 100M/1G/10G optical bypass in SC/ST/LC connectors
  • Optical bypass switching time <10ms with Low insertions loss
  • Provides rotary switch to set delay boot time (0~180 seconds)
  • Relay output for power failure warning
  • Redundant dual DC input power 12/24/48VDC (9.6 ~ 60VDC)
  • IP30 rugged metal housing and fanless
  • Wide operating temperature -20 ~ 75°C
  • Heavy industrial grade EMS, EMI, EN61000-6-2, EN61000-6-4,CE, FCC certified
The IBP-202 supports the function of optical path Normal mode and Bypass mode for fiber optical networks. It offers a simple mechanism to switch both of upload and down load fiber path when a power system failure occurred, and a path restores when power back. It offers a simple way to reduce the risk of optical network Node-Down which is caused by the power system.
