The Optical Bypass Switch automatically bypasses faulty network nodes during power outages, ensuring continuous optical fiber communication in ring or linear network architectures.
- Normal Mode: When powered on, the switch forwards Ethernet packets between three switches
- Bypass Mode: During power failure, directly forwards Ethernet packets between two fiber switches, bypassing the middle switch
Also known as a bypass TAP, it automatically switches faulty nodes during power outages or failures to secure complete optical transmission.
Primarily used to prevent network outages and protect networking systems in optical telecommunications. Suitable for ring or linear fiber network architectures including railway communication systems, factory automation, and power substations.
Available in SC connector singlemode (4 port), LC singlemode (4 port and 8 port), and LC multimode (4 port and 8 port) configurations.
Yes, this device operates at the optical transmission level without involving network protocols. Compatible with any switches supporting optical rates from 100M to 100G.
Olycom offers two types: standalone units that connect with optical ports of different speeds and brands, and integrated bypass switches combining industrial managed Ethernet switches with optical switching functionality.
