Product Description: Nokia 3HE10452AA
10GBase-BX: This is the key technical identifier.
10G: Represents a transmission rate of 10 Gigabits per second (10Gbps).
Base: Indicates "baseband" transmission.
BX: Stands for Bi-Directional (bidirectional) on Single Fiber (single fiber).
This is the most important feature, meaning it only requires one fiber to simultaneously send and receive data.
SFP+: The form factor of the module, a standard hot-swappable optical module specification, downward compatible with SFP but supporting higher speeds (10G).
SMF: Single-mode fiber, suitable for long-distance transmission.
1490nm Tx / 1550nm Rx: Wavelength information.
Tx (Transmit, transmit): This module uses a 1490nm wavelength laser to send data.
Rx (Receive, receive): This module uses a 1550nm wavelength to receive data.
By using two different wavelengths, bidirectional communication on a single fiber is achieved.
80km: The maximum transmission distance is 80 kilometers. This is an ultra-long-distance module, falling into the "long-distance" category.
LC: The type of optical fiber connector, a small square connector, currently the most mainstream type.
DOM: Digital Optical Monitoring. This is a very important function that allows network management systems (such as Nokia's router/switch operating systems) to monitor the module's working status in real time,
such as: Transmit optical power, receive optical power, temperature, supply voltage, laser bias current, which greatly facilitates network operation and maintenance and fault diagnosis.
Summary Description: This is a 10G SFP+ optical module produced by Nokia that supports 80 kilometers of ultra-long-distance transmission and single-fiber bidirectional communication.
It achieves the sending and receiving tasks by using two different wavelengths, 1490nm and 1550nm, on a single single-mode fiber and has digital monitoring capabilities. Usage scenarios
This type of optical module is mainly used in scenarios where fiber resources need to be saved and long-distance point-to-point connections are required. Here are several typical application cases:
1. Telecommunication operator networks (the most core application)
Metropolitan area network access and convergence: It is used to transmit data from business nodes distributed throughout the city (such as base station controllers,
enterprise access points) back to the core machine room of the metropolitan area network, with distances typically ranging from tens of kilometers.
Areas with tight fiber resources: In some old urban areas or regions where pipeline resources are full, the cost of laying new fibers is extremely high.
By using this single-fiber bidirectional module, the utilization rate of existing fibers can be doubled, and the tasks previously handled by two fibers can be accomplished with just one.
2. Interconnection between enterprise networks and data centers
Long-distance interconnection between campuses or buildings: When large enterprises, universities,
or government agencies have multiple campuses or data centers that are far apart (up to 80 kilometers) and need high-speed (10G) interconnection, this module is very suitable.
For example, connecting the headquarters data center with the backup data center.
Reducing fiber cabling costs: Even if fiber resources are not tight, using a single-fiber solution can directly reduce the number of fiber cores required, lowering cabling costs and complexity.
3. Dedicated line services
Network service providers offer 10G dedicated line access services for the "last mile" to connect customer sites to the network POP points of the operator.
