FAQs

Q: What is the maximum transmission distance for the QSFP-200G-SR4?
A: The transceiver supports up to 100 meters over OM4 multi-mode fiber and 70 meters over OM3 multi-mode fiber, making it suitable for intra-rack and across-rack data center deployments.

Q: Is this transceiver compatible with QSFP28 ports?
A: No, QSFP56 modules require QSFP56 or QSFP-DD ports. While QSFP56 ports can accept QSFP28 modules, QSFP56 transceivers cannot be used in QSFP28 ports due to different electrical specifications.

Q: Does the QSFP-200G-SR4 support breakout configurations?
A: Yes, on supported platforms, this transceiver can be configured for breakout mode to 2× 100G or 4× 50G connections, providing flexible migration paths from lower-speed infrastructure to 200G.

Q: What type of fiber cable is required for this transceiver?
A: The QSFP-200G-SR4 requires MTP/MPO-12 multi-mode fiber patch cables with UPC (Ultra-Physical Contact) connectors. OM4 fiber is recommended for maximum 100m reach.

Q: Is this transceiver suitable for high-performance computing and AI workloads?
A: Absolutely. The 200G QSFP56 SR4 provides the high bandwidth and low latency required for modern AI, machine learning, and high-performance computing environments, particularly in spine-leaf data center architectures.
