2. Typical Application Scenarios
1. Data Center Short-Distance Interconnection
Server-Switch Connection: In high-density data centers, used to connect blade servers with access layer switches. For example,
AWS data centers use FTLX8571D3BCV to build 10G TOR (Top-of-Rack) networks, supporting high-bandwidth requirements for virtual machine migration and containerized applications.
Storage Area Network (SAN): Connects NAS or SAN storage devices to achieve low-latency data access. For example,
the EMC Unity series storage uses FTLX8571D3BCL module to achieve stable 400-meter transmission on OM4 fiber, supporting real-time writing of video surveillance recordings.
2. Enterprise Campus Network
Backbone Link Upgrade: Replace traditional 1G copper cables to enhance the core layer bandwidth of the campus network. For example,
a financial institution uses FTLX8571D3BCV module to upgrade the connection rate from 1G to 10G between branches and headquarters, supporting high-definition video conferences and big data analysis.
Multi-Floor Interconnection: In office buildings, connects access switches on different floors via OM3 MMF. For example, H3C S5820V3 switch paired with FTLX8571D3BCV achieves 300-meter cross-floor 10G interconnection.
3. Industrial Automation and Intelligent Transportation
Factory Workshop Control: In automotive manufacturing production lines, the -5°C low-temperature adaptability of FTLX8571D3BCL ensures stable operation of equipment in winter,
connects PLC and edge computing nodes, supports real-time quality detection systems.
Rail Transit Communication: Wi-Fi hotspots for high-speed rail carriages are connected to the on-board backbone network. For example,
the low-power design of FTLX8571D3BCV can reduce the load on the on-board power supply, and its metal casing protection meets the requirements for vibration and electromagnetic interference.
4. Cloud Computing and High-Performance Computing
Internal Interconnection of Cloud Platform: In OpenStack or Kubernetes clusters, the FTLX8571D3BCV module supports high-speed transmission of east-west traffic in the virtual network.
For instance, a certain regional node of Alibaba Cloud uses this module to build a 10-Gigabit VXLAN network, supporting the dynamic scheduling of elastic computing resources.
Scientific Research Computing Cluster: Connects high-performance computing (HPC) nodes to achieve data interaction for parallel computing tasks.
For example, a university's meteorological simulation center uses the FTLX8571D3BCL module to implement 400-meter low-latency interconnection on OM4 optical fiber, accelerating climate model computations.
III. Deployment Considerations
1. Fiber Selection:
FTLX8571D3BCL: Preferentially use OM4 MMF for 400-meter transmission, and keep OM3 MMF within 300 meters.
FTLX8571D3BCV: Both OM3/OM4 fibers are acceptable, but OM4 can increase bandwidth margin.
2. Host Compatibility:
FTLX8571D3BCL: Ensure that the host PHY supports the limited receiver (such as Broadcom BCM57810), and configure EDC parameters according to the manufacturer's recommendations.
FTLX8571D3BCV: Plug-and-play, wide compatibility, but some devices (such as certain old Cisco switches) need to upgrade firmware to support DOM functionality.
3. Temperature Management:
In high-temperature environments (such as data center hot aisles), it is recommended to use FTLX8571D3BCL, as its wide temperature range of -5°C to +70°C can adapt to larger temperature differences.
4. Optical Power Testing:
Use an optical power meter (such as EXFO FTB-7200) to verify link loss, ensuring the transmission power is between -9.5dBm and -3dBm, and the receiving sensitivity is better than -12.5dBm.
IV. Compatibility and Certification
Standard Compliance: All comply with SFF-8431/SFF-8432, IEEE 802.3ae 10GBASE-SR, and SFF-8472 DOM interface standards.
