10G SFP+ LR40 Optical Transceiver — 40km at 1310nm

The Sate Optics ST-10G-SFP-LR40 is a 10G SFP+ optical transceiver for single-mode links up to 40km at 1310nm. With 0 ~ +5 dBm launch power and -15 dBm sensitivity, it delivers ER-class reach in the 1310nm window for metro aggregation and long campus spans.

Why This Module

  • 40km over duplex SMF: 1310nm optics with 0 ~ +5 dBm launch power
  • ER-class reach at 1310nm: suits plants standardised on 1310nm optics
  • 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.
