GLSUN Bypass Unit integrates optical switching modules

Bypass Unit integrates optical switching modules and heart rate monitoring, which provides bypass protection when optical network node equipments appear power interruption, hardware failure, software deadlock etc to insure the normal signal transmission. Mainly used in flow control equipment, signal safty analysis, gigabit data communications and other fields.

Features
1U Plug-type design, support four ways, mixed insertion for single mode and multimode.
USB design for power supply and communication.
Diversification of heartbeat. Support independent control or group control.
Customizing production of function and appearance etc can be provided.
