SPOBP0096AE2 OBP Optical Bypass Protection Subsystem: Complete Product Guide
This article is based on actual SPOBP0096AE2 product specifications, including complete product overview, features, specifications, NMU control board, and OBS protection card information
I. Product Overview
The OBP optical bypass protection subsystem (Bypass) is an intelligent optical path switching system. It belongs to the physical layer equipment and is applied to pure optical network environment. It can automatically identify the power supply status and optical signal output status of network nodes. When the local optical equipment fails (including power interruption, hardware or software failures), it can instantaneously switch to the bypass optical path, and the communication line will bypass the local equipment (i.e. the fault node), thus avoiding the total resistance obstacle caused by the fault node and ensuring the normal system connectivity.
II. Product Features
- Applicable to all kinds of gateway equipment: Such as DPI equipment, firewall, IPS, UTM, IDP, spam gateway, anti-virus gateway, special DDoS equipment, special logic isolation equipment in all fields, etc.
- Support power-off and power-on retention function: Bypass equipment's power-off or power-on does not affect the switching status of work routing to ensure the normal operation, and has hot-swap function.
- Unique power storage function: To ensure that no wrong switch occurs even when the bypass equipment itself is power off.
- Automatic instantaneous switch to fault nodes: Without human intervention, switching time <20ms.
- OBP card and network management card are independent: Of each other and have no influence on each other.
- Support multi-kinds of graphical interface network management: Such as SNMP, Web.
- Support AC power 220V, DC power -48V: And 1+1 power input protection.
- 1U pluggable rack mount: Flexible capacity configuration.
