Product Features
Technical Overview
This expansion module implements 10 Gigabit Ethernet technology with 10GBase-X network standards, ensuring compatibility with existing 10GbE optical fiber infrastructure. Each of the eight SFP+ ports operates independently, supporting full-duplex communication for maximum throughput in demanding network environments.
The module's optical fiber media support includes both singlemode and multimode fiber types when paired with appropriate SFP+ transceivers, though specific wavelength and reach capabilities depend on the installed transceiver modules. No integrated DOM or DDM monitoring is specified at the module level—monitoring functions reside within the host device or individual transceivers.
Key Product Advantages
The AT-SBX81XLEM/XS8 expansion module provides a cost-effective density upgrade for networks requiring additional 10GbE optical ports without replacing core switching hardware. Its plug-and-play design simplifies network expansion while maintaining compatibility with existing Allied Telesis ecosystem components.
Scalable Port Density
Add eight dedicated 10GbE SFP+ ports to compatible switches, increasing uplink capacity or server connectivity in data center, enterprise, or service provider environments.
- Eliminates need for standalone 10GbE switches
- Preserves existing switch investment
- Maintains uniform management interface
Optical Fiber Optimization
Designed specifically for optical fiber media, the module ensures reliable high-speed connectivity over longer distances compared to copper-based solutions, with lower latency and immunity to electromagnetic interference.
- Supports both singlemode and multimode fiber
- Enables campus or data center backbone links
- Reduces cable bulk and weight
Deployment / Use Cases
This expansion module serves as a strategic network upgrade component for organizations scaling their optical fiber infrastructure. It is particularly valuable in environments where gradual capacity increases are preferred over wholesale hardware replacement.
Common deployment scenarios include adding 10GbE uplinks between distribution and core switches in enterprise networks, providing high-speed server connections in virtualized data centers, or extending optical backbone links in campus or metropolitan area networks. The module's environmentally friendly manufacturing also aligns with sustainable IT initiatives.
Data Center Server Connectivity
Connect virtualized servers or storage arrays to top-of-rack switches with 10GbE optical links, reducing bottlenecks in virtual machine migration, backup operations, and live data replication.
Network Aggregation Layer
Increase uplink capacity between access and distribution layers in multi-tier network designs, ensuring sufficient bandwidth for converged voice, video, and data traffic across optical fiber backbones.

FAQ
What type of SFP+ transceivers work with this expansion module?
The AT-SBX81XLEM/XS8 expansion module accepts standard SFP+ optical transceivers compatible with 10GBase-X specifications. You can use either singlemode or multimode SFP+ transceivers depending on your fiber cable type and distance requirements. Always verify transceiver compatibility with your specific Allied Telesis switch model before purchase.
Can this module be used with copper SFP+ transceivers?
While the module is designed for optical fiber applications, it may support 10GBASE-T copper SFP+ transceivers if they are compatible with the host switch's specifications. However, the product documentation emphasizes optical network usage, so for optimal performance with copper connections, consult Allied Telesis compatibility guides or technical support.
Does this expansion module support DOM/DDM monitoring?
The module itself does not include integrated DOM or DDM monitoring capabilities. Monitoring functions for temperature, voltage, laser bias, and optical power are typically provided by the host networking device or individual SFP+ transceivers that support these features. Check your transceiver specifications for monitoring support.
What is the maximum distance supported by this module?
Distance capabilities depend entirely on the SFP+ transceivers installed in the expansion slots. With appropriate transceivers, the module can support reaches from 100 meters over multimode fiber to 40 kilometers or more over singlemode fiber. Always pair the module with transceivers matched to your specific distance and fiber type requirements.
