10G XENPAK LR20 Optical Transceiver — 20km Single-Mode for Installed-Base Networks
The Sate Optics ST-10G-XENPAK-LR20 is a 10G XENPAK optical transceiver for single-mode links up to 20km. 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
- 20km reach: 1310nm optics for XENPAK 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.
