Temperature Range: Commercial-grade operating temperature of 0°C to +70°C, Suitable for most data centers and enterprise environments.
3. Digital Diagnosis and Management
DOM Function: Monitors optical power, temperature, voltage, bias current, etc. parameters in real time through I²C interface (following SFF-8636/SFF-8665 standard), supports fault warning and remote management.
Protocol Compatibility: Compatible with 100G Ethernet (100GBASE-SR4), 4x25G Split (Breakout) applications, and CPRI/eCPRI protocols (cellular base station front haul).
2. Typical Application Scenarios
1. Data Center Short-Distance Interconnection
TOR (Top-of-Rack) Architecture: Connects servers with access layer switches. For example, an AWS data center uses the MMA1B00-C100D module on OM4 fiber,
to achieve 100-meter 100G connection, supporting high-bandwidth requirements for containerized applications and virtual machine migration.
Storage Area Network (SAN): Connects SSD arrays with servers. For example, the NetApp AFF A400 storage uses this module to achieve low-latency.
data access on OM4 fiber, supporting real-time read and write for financial transaction systems.
2. High-Performance Computing (HPC) Cluster
GPU/CPU Node Interconnection: Connects GPU servers with InfiniBand switches in deep learning or scientific computing clusters. For example,
the NVIDIA DGX-1 system uses the MMA1B00-C100D module to build a 100G SR4 network, supporting high-speed data interaction for distributed training.
Parallel File System: Connects computing nodes with parallel storage in oil exploration or weather simulation scenarios.
For example, IBM Spectrum Scale uses this module to achieve 100G bandwidth, accelerating the analysis and processing of massive data.
3. Enterprise Campus Network
Core Layer Upgrade: Replaces traditional 10G links to increase the backbone bandwidth of the campus network. For example,
the Shanghai park of a multinational company achieved 100G interconnection across buildings on OM4 optical fibers using the MMA1B00-C100D module, supporting 4K video conferencing and big data analysis.
Multi-floor interconnection: In office buildings, different floors' access switches can be connected through OM3 MMF. For instance, the H3C S12508E switch,
when paired with this module, enables 100G transmission over a distance of 70 meters.
4. 5G Communication Network
Front-haul and mid-haul networks: In the deployment of 5G base stations, it is used to connect distributed units (DU) and centralized units (CU).
For example, the HUAWEI 5G base station uses the MMA1B00-C100D module to transmit eCPRI signals on OM4 optical fibers, supporting the high bandwidth requirements of Massive MIMO antennas.
Edge computing: In smart cities or industrial Internet of Things scenarios, it connects edge servers with 5G base stations. For instance,
a certain edge node of China Mobile uses this module to achieve 100G data return, supporting real-time traffic analysis for autonomous driving.
III. Deployment Considerations
1. Fiber Selection and Link Budget
Recommended Fiber: Preferentially use OM4 MMF for 100-meter transmission, and keep OM3 MMF within 70 meters. Avoid using OM1/OM2 fibers as they have insufficient bandwidth.
Optical Power Testing: Use an optical power meter (such as EXFO FTB-7200) to verify link loss and ensure the transmit power is between -8.4dBm and +2.4dBm, and the receiving sensitivity is better than -10.3dBm.
2. Equipment Compatibility
Mainstream Manufacturers' Compatibility: Seamless integration with mainstream switches such as Cisco Nexus 93180YC-FX3,
Huawei CE6881, and H3C S12508E. For example, Cisco switches can directly recognize this module and enable DOM functionality.
Firmware Update: Some older devices (such as certain Juniper switches) need to upgrade their firmware to the latest version to support the 100GBASE-SR4 protocol and shunting function.
3. Heat Dissipation and Power Consumption Management
Environmental Control: In high-density racks, it is recommended to keep the temperature around the module within 70°C. Increasing fans or optimizing the cabinet layout can improve the heat dissipation efficiency.
Power Consumption Planning: The power consumption of a single module is ≤ 2.2W. Ensure the power supply capacity of the switch ports (such as the Cisco Nexus 9300 series, the maximum power supply for a single port is 3.5W).
4. Fiber Cables and Connections
Cable Type: Use MPO-12 to MPO-12 multimode cables (OM4 or OM3) to ensure the fiber core number matches (4 cores for transmission, 4 cores for reception, and the rest as spare).
Cleaning and Maintenance: Regularly use dedicated cleaning tools (such as MPO fiber end face cleaning pen) to clean the interface to avoid increased optical loss due to dust.
IV. Compatibility and Certification
Standard Compliance: Compliant with international standards such as RoHS, SFP+ MSA, IEEE 802.3bm 100GBASE-SR4, SFF-8636/SFF-8665 DOM interface.
