10/25G SFP28 LR Dual-Rate Optical Transceiver — 10km Single-Mode for 10G and 25G

The Sate Optics ST-10/25G-SFP28-LR is a dual-rate SFP28 optical transceiver that runs at both 10G and 25G. It operates at 1310nm over duplex LC single-mode fiber for up to 10km, so one stocked optic serves 10G LR ports today and 25G ports after the switch refresh — no second inventory, no mid-migration swap.

Why This Module

  • Dual-rate 10/25G: auto-matched to the port speed, one module for both generations
  • 10km over duplex SMF: 1310nm optics on a duplex LC pair
  • DDM monitoring: real-time optical power, temperature and voltage readings, 0~70℃ commercial range
  • Compatible with your platform — coded for major networking platforms, including Cisco, Juniper, Arista, Huawei, Nokia, H3C and ZTE; 100% tested before shipment.
