FAQ
Q: What distinguishes SR4 from other 100G transceiver types like LR4 or CWDM4?
A: The 100GBASE-SR4 designation indicates a short-range, 4-lane parallel optics design optimized for multimode fiber. Unlike LR4 or CWDM4 which use wavelength-division multiplexing over single-mode fiber for distances up to 10km, the SR4 architecture employs four separate 850nm VCSEL channels transmitting simultaneously through OM3/OM4 MMF. This approach delivers cost-effective 100Gbps connectivity for data center environments where link distances remain under 100 meters.
Q: Can this 100G module support 4×25G breakout connections?
A: Yes, this 100G QSFP28 SR4 transceiver fully supports 4×25G breakout functionality. Using an MPO to 4×LC breakout cable, a single 100G port can be split into four independent 25GbE SFP28 connections. This capability enables flexible network designs, allowing gradual migration from 25G server connectivity to 100G aggregation while maximizing port utilization in high-density switch deployments.
Q: What fiber cabling is required for this 100G SR4 optical module?
A: This 100G SR4 transceiver requires 12-fiber ribbon cable terminated with MTP/MPO-12 connectors. For full-duplex operation, 8 fibers are active (4 TX + 4 RX). The module achieves 100m reach over OM4 laser-optimized multimode fiber, or 70m over OM3 fiber. Ensure your MPO connector uses UPC polish and verify polarity matches your cabling configuration for proper channel alignment.
Q: How does the built-in CDR enhance 100G signal quality?
A: The integrated Clock and Data Recovery (CDR) circuitry on both transmit and receive paths compensates for timing jitter and signal degradation that naturally occurs during high-speed optical transmission. This capability maintains clean eye diagrams at each 25Gbps lane, enabling reliable operation even approaching the maximum 100m OM4 distance. The CDR also provides broader compatibility with host switch SerDes implementations.
Q: What customization options are available for bulk orders?
A: FB-LINK offers customized 100G QSFP28 SR4 modules configured for compatibility with your specific switch platforms. We support major networking equipment brands including Cisco, Juniper, Arista, Huawei, Dell, HP, and others. Contact our sales team to discuss your requirements and receive a quotation based on your specifications and volume needs.
Q: Why is the ≤1.8W power consumption significant for data center deployments?
A: Ultra-low power consumption directly impacts data center operational costs and density capabilities. At just 1.8W maximum, this energy-efficient 100G optical module generates less heat than competing designs (often 2.5-3.5W), enabling higher port counts per switch without exceeding thermal envelopes. Over thousands of ports, the power savings compound into significant reductions in electricity costs and cooling requirements, improving both TCO and environmental sustainability.
