8 port optical fiber Switch managed industrial network switch witch D2*2B bypass 1


1. Critical Industrial Control Networks (PLC / SCADA)
* In PLC and SCADA systems, switches are often deployed in critical communication paths
* In case of power failure or device malfunction, the built-in Bypass function automatically maintains link connectivity
* Prevents network interruption caused by single device failure
* Ensures continuous data transmission in mission-critical industrial automation environments

 
2. Video Surveillance & Security Systems
* Widely used in IP surveillance networks with daisy-chain or ring topologies
* Traditional switches may cause complete link failure if a node loses power
* With Bypass functionality, the link remains active even when the switch is powered off
* Guarantees uninterrupted video transmission for security-critical applications
 
3. Daisy-Chain Topology Deployments
* Common in industrial environments to reduce cabling costs
* However, traditional daisy-chain networks are vulnerable to single-point failures
* With Bypass-enabled switches:
Failed nodes are automatically bypassed
Downstream communication remains unaffected
* Significantly improves fault tolerance in linear network architectures

FAQ

1. What is an optical bypass switch?
A: it is also named a bypass TAP used for automatically switching faulty nodes when power outages or failures take place, this secures the complete optical transmission.

2. Where it is used?
A: It is mainly used to prevent network outages, protect the network or control the networking system in the optical telecommunication. It can be used in ring or linear fiber network architectures such as railway communication systems, factory automation, and power substations.
 
3. What are the ordering options?
A: There is SC connector singlemode(4 port), LC singlemode(4 port and 8 port) and LC multimode(4 port and 8 port)for your choice as below photos.
 
4. Can your optical bypass units work with different switches?
A: Yes, this device is about the optical transmission level and not involving any network protocols.
It can work with any switches of different optical rates(100M/1G/2.5G/10G/25G/40G/100G).
 
5. What is the switching time?
A: No more than 10ms, this depends on the optical switch component inside.
