Arista QSFP-200G-SR4-Arista | 200G SR4 QSFP56 Transceiver, 850nm, 100m MMF, MPO-12

Q: What fiber type and distance does the QSFP-200G-SR4 support?
A: The QSFP-200G-SR4 operates over parallel multimode fiber (MMF) using an MPO-12 connector. It supports transmission distances up to 70 meters on OM3 fiber and up to 100 meters on OM4 fiber, making it ideal for intra-data center connections.

Q: Is the Arista QSFP-200G-SR4 backward compatible with 100G ports?
A: Yes, the QSFP-200G-SR4 supports dual-rate operation at 200G and 100G. It can be used in QSFP56 ports and is backward compatible when inserted into compatible 400G QSFP-DD ports, which will operate at 200G. However, QSFP56 modules cannot be used in older QSFP28 (100G) ports.

Q: What standards does this transceiver comply with?
A: The QSFP-200G-SR4 is fully compliant with IEEE 802.3bs 200GBASE-SR4, SFF-8665, QSFP56 MSA, and CMIS Rev 4.0 standards. It uses PAM4 modulation at 850nm wavelength with VCSEL laser technology, ensuring interoperability with standards-compliant equipment.

Q: Can I break out a 200G port using this transceiver?
A: The QSFP-200G-SR4 itself does not provide breakout capability, as it is designed for native 200G connectivity. However, you can achieve breakout from 200G to 4x50G by using multimode MTP-to-4xLC duplex patch cables with 50G SFP56 SR optical modules at the remote end.

Q: What are typical deployment scenarios for this transceiver?
A: The QSFP-200G-SR4 is ideal for high-density data center spine-leaf architectures, high-performance computing (HPC) networks, enterprise core and distribution layers, cloud computing environments, and server-to-switch connectivity where high bandwidth and low latency are critical within short to medium distances.
