Typical Applications

✨Enterprise Long‑Distance Backbone Uplinks: Delivers high-bandwidth 10G long‑haul optical uplinks across multi-building campus sites or remote branch offices over OS2 (G.652) single‑mode fiber up to 40km (backward compatible with OS1).

✨Data Center Inter-Building Links (40km DCI): Interconnects geographically separated data center facilities, disaster recovery (DR) sites, and regional halls over 40km single-mode fiber links without requiring external optical amplifiers.

✨Core & Aggregation Networking (MX & QFX Platforms): Pre-programmed with native SFPP-10GE-ER-B EEPROM code to provide high-density, zero-alarm 10G optical backbone connections for MX series line cards (e.g., MICs, MPCs) and QFX data-center switches.

✨Security Gateway Interconnects & Expansion: Expands secure, high-throughput 10G optical WAN ports for SRX series security firewalls (SRX380, SRX1500, SRX4100, SRX4200, SRX4600) with clean Junos syslog logging.

✨Harsh-Environment & Industrial Field Deployments: Built with a true industrial-grade operating case temperature range ( -40°C to +85°C), fully supporting sub-zero cold-site startup and elevated thermal conditions in non-climate-controlled outdoor cabinets, roadside enclosures, and industrial edge nodes.
