Arista OSFP-200G-2LR4-Arista | 200G OSFP Transceiver, Dual LC, Single-Mode, 10km

Q: What is the difference between OSFP-200G-2LR4 and 400G OSFP transceivers?
A: The OSFP-200G-2LR4 operates at 200G using 8 x 25G NRZ electrical lanes, while 400G OSFP transceivers use 8 x 50G PAM-4 lanes. The 200G module is designed for interoperability with legacy 100G QSFP and 25G SFP ports, making it ideal for networks transitioning from 100G to higher speeds.

Q: Can this transceiver interoperate with 100G equipment?
A: Yes, the OSFP-200G-2LR4 is optically interoperable with 100GBASE-LR4 QSFP modules. Each of the two LC duplex connectors supports a physically separate 100G-LR4 link, allowing flexible connectivity with existing 100G infrastructure up to 10km.

Q: What platforms support the OSFP-200G-2LR4 transceiver?
A: This transceiver is supported on Arista switches with OSFP ports, such as the 7060X4 series and other platforms with OSFP interfaces. The port must be configured for 200G operation using 8 x 25G NRZ electrical lanes. Refer to Arista's Transceiver and Cable Guide for platform-specific compatibility.

Q: What are the typical deployment scenarios for this transceiver?
A: The OSFP-200G-2LR4 is ideal for data center spine-leaf architectures, campus core interconnects, and long-haul links requiring 200G bandwidth over distances up to 10km. It suits environments upgrading from 100G while maintaining backward compatibility with existing fiber infrastructure.

Q: Does this transceiver support breakout configurations?
A: Yes, with its dual LC duplex connectors, the OSFP-200G-2LR4 effectively provides 2x 100GBASE-LR4 links from a single 200G OSFP port. This allows flexible network design without requiring additional breakout cables, simplifying cabling and reducing costs in mixed-speed environments.
