Key Differences:
- Distance: The QSFP-100G-LR4 supports much longer distances (up to 10 km) over single-mode fiber, making it ideal for long-distance connections. In contrast, the QSFP-100G-SR4 is designed for shorter-range connections (up to 100 meters) using multi-mode fiber.
- Wavelength: The QSFP-100G-LR4 uses a longer wavelength (1264.5nm to 1337.5nm) for single-mode fiber, which is suited for long-range communication, while the QSFP-100G-SR4 uses 850nm, which is typical for multi-mode fiber.
- Connector Type: The QSFP-100G-LR4 uses LC duplex connectors, commonly used in single-mode fiber networks, while the QSFP-100G-SR4 uses MTP/MPO connectors, designed for multi-fiber configurations typical in data centers and shorter-range applications.
