ST-10G-SFP-LR20

10G SFP+ LR20 Optical Transceiver — 20km Single-Mode Extended LR

The Sate Optics ST-10G-SFP-LR20 is a 10G SFP+ optical transceiver for single-mode links up to 20km. It keeps standard 1310nm LR optics but with a higher launch power (-1 ~ +4 dBm), doubling LR reach for metro access and larger campuses without moving to 1550nm ER optics.

Why This Module

• 20km over duplex SMF: 1310nm optics with a boosted launch budget
• Twice the LR reach: covers the gap between 10km LR and 40km ER
• 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.
