Key Differences:
- Data Rate: The QSFP-40G-SR4 supports a much higher data rate (40 Gbps) compared to the SFP-10G-SR, which supports 10 Gbps. This makes the QSFP-40G-SR4 suitable for high-performance networking requiring faster throughput.
- Distance: The SFP-10G-SR has a longer distance support for 10G Ethernet (up to 300 meters on OM3 fiber), while the QSFP-40G-SR4 supports up to 100 meters for 40G Ethernet, but this is on higher-performance OM4 fiber.
- Connector Type: The QSFP-40G-SR4 uses a MTP/MPO connector, designed for multi-fiber configurations, while the SFP-10G-SR uses an LC connector, which is more common in simpler single-fiber setups.
Both transceivers are designed for different network speeds (10G vs. 40G) and use cases, with the QSFP-40G-SR4 aimed at high-performance, high-throughput environments and the SFP-10G-SR suitable for standard 10G Ethernet applications.
