The JBX01987 100BASE-ZX SFP transceiver is an advanced optical module engineered for enterprise-grade network infrastructure requiring extended transmission distances. Delivering 100MB data rates at 1550nm wavelength, this transceiver achieves exceptional 80km transmission capability over 9/125 singlemode fiber—significantly exceeding standard short-reach modules. Key Technical Features: The duplex LC/UPC fiber connector provides industry-standard connectivity with low insertion loss and excellent return loss characteristics. The singlemode fiber core supports long-distance propagation with minimal signal degradation, ensuring reliable data transmission across campus networks and metropolitan area networks. Compatibility & Integration: Designed as a direct replacement for Juniper EX-SFP-1FE-LH modules, this transceiver integrates seamlessly into Juniper switching environments without requiring firmware modifications or compatibility adjustments. IEEE 802.3u compliance ensures interoperability with standards-based equipment. Reliability & Compliance: Built with metal case housing and laser transmitter components, this module withstands demanding deployment conditions. Comprehensive certifications include RoHS/ELV compliance, Class 1 laser designation, UL/FDA approval (21CFR 1040.10), and TUV certification. Operating temperature range of 0-70°C (32-158°F) supports installation in climate-controlled data centers and outdoor cabinet environments. Value Proposition: Offers significant cost savings compared to OEM Juniper modules while maintaining equivalent performance and reliability. Custom brand programming is available for resellers and system integrators. All units include 90-day limited warranty, with free standard shipping on orders exceeding $99. Applications: Ideal for data center interconnect, disaster recovery sites, campus backbone networks, and any deployment requiring 80km transmission capability over single fiber strand. The extended reach reduces infrastructure complexity and cost while maintaining 100BASE-TX performance standards.
