Hardware / Transceivers and cables / 800G OSFP 2×SR4

800G OSFP twin-port SR4 multimode transceiver

The short-reach, multimode option for switch ports. Cheaper per link than DR4 when servers and leaf switches sit in the same or neighboring racks.

Common pitfalls

  • Both ends must be SR4 on multimode fiber. SR and DR optics do not interoperate.
  • 50 m is tight for spine links between rows. Use DR4 on single-mode for anything beyond the row.
