● Product 1: 400G DCI-BOX
400G DCI-BOX FW-8800 mainly aims at 400G high-rate transmission.One service card of 400G DCI Box support 4x100G(QSFP28) for clients side, and 1x400G(CFP2) for line side. With 4 slots in 1U rack mount ,the DCI-Box max support 4x 400G transponder board,total capacity 1.6Tbps .The products are mainly used in data center DCI interconnection and city access and convergence. Provide users with a variety of different capacity, different transmission distance, intelligent service applications of optical transmission solutions.
●1U chassis modular design, single board with hot plug design, support smooth upgrade, according to the demand can flexibly expand or delete the business.
●Dual power supply, compatible with AC 110V~260V or DC-48V.
●Complete network management protocol: supports WEB, SNMP, CLI, TLI and other network management interfaces.
●Support dual network management cards, 1+1 network function.
Application:
● Product 2: Optic bypass(OBP)
OBP is an automatic switching system applied to the field of optical fiber communication and can automatically bypass the fault. It can automatically identify the power supply state of the network nodes, and instantly switch the optical path when the protected node loses power, so as to avoid the full resistance obstacles of the network nodes and keep the system connection normal.
●Automatic switching, and no human intervention
●Switch when the protected device loses power
●Reduce the various losses caused by the network node failure
●Increase the reliability of the transmission network
●Support for manual switching and automatic switching selection
●Large-screen LCD display
●Support sound and light alarm
●Wide range dual power supply input DC +5V TO +36V
● Guide rail installation
The OBP optical line protector can be applied to highway and tunnel video surveillance scenarios, as shown below:
The application adopts a single fiber chain network structure (as shown in the figure: A-C-B). Once a node in the middle fails (power failure), the communication of all subsequent nodes will be interrupted;In order to increase the online rate of video monitoring of highway and tunnel, the OBP produced by our company can be increased.When a node has a failure (power failure), automatically bypass the fault node to ensure the normal working communication of other nodes.
