EX-SFP-1GE-LX40K, Juniper EX Series SFP Module, 1000BASE-LX/SMF 40km/LC Connector

The Juniper EX-SFP-1GE-LX40K is a carrier-grade 1 Gigabit Ethernet SFP fiber module designed for stable long-distance links in enterprise and service provider networks. This Juniper optical module supports 1000BASE-LX over single-mode fiber up to 40 km, making it a solid choice for campus backbones, metro access, and data center interconnects. With a 1310 nm wavelength and Duplex LC interface, the EX-SFP-1GE-LX40K integrates easily into existing SMF cabling systems used across Asia, Europe, Africa, and North America.

For distributors and resellers, the EX-SFP-1GE-LX40K offers a reliable, standardized SFP (Small Form-factor Pluggable) option that is MSA compliant and compatible with Juniper Networks high-performing switching and routing platforms. Its low typical power consumption of 1.0W helps optimize power budgets in dense deployments, while hot-pluggable design simplifies stock rotation and field replacement without downtime.

For small and mid-size system integrators, this module reduces project risk by providing predictable 1G optical performance and extended 40 km reach for point-to-point or ring topologies in telecommunication and data network projects. Digital Optical Monitoring (DOM) support allows proactive monitoring of key optical parameters, so integrators can troubleshoot faster and improve SLA delivery for customers.

For end users, including enterprises, government, and campus networks, the Juniper EX-SFP-1GE-LX40K helps build stable fiber uplinks between wiring closets, branches, and data centers. The supported operating temperature range of 0 to 70 °C and humidity from 5% to 95% non-condensing fits typical indoor environments across different climates. Enhanced security features and support for advanced QoS functions make it suitable for converged voice, video, and data services where consistent performance and compliance with international industry standards are important.
