10G X2 LR Optical Transceiver — 10km Single-Mode for Installed-Base Networks
The Sate Optics ST-10G-X2-LR is a 10G X2 optical transceiver for single-mode links up to 10km. It runs at 1310nm over single mode fiber with SC duplex connectivity, keeping first-generation 10G platforms in service with fresh, coded optics.
Why This Module
- 10km reach: 1310nm optics for X2 cages
- Fresh spares for legacy fleets: new-production modules, not refurbished pulls
- 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.
