The JBX02141 1000BASE-BX10-U SFP Transceiver is a premium-quality optical networking module specifically designed to meet demanding long-distance connectivity requirements. As a direct Juniper EX-SFP-GE10KT13R14 compatible replacement, this transceiver seamlessly integrates into existing Juniper switch architectures without requiring firmware modifications or compatibility workarounds. Technical Specifications and Performance: This module operates at 1Gbps data rates over singlemode fiber infrastructure, delivering transmission distances up to 10km—ideal for campus interconnections, data center expansions, and enterprise WAN applications. The 9/125 micron singlemode fiber core minimizes modal dispersion, ensuring signal integrity over extended distances. The transceiver employs bidirectional wavelength operation: 1310nm for transmission and 1490nm for reception, enabling full-duplex communication across a single fiber strand through wavelength division multiplexing principles. Connectivity and Build Quality: The simplex LC/UPC connector delivers industry-standard low-loss performance with consistent return loss characteristics. The precision-engineered metal case provides electromagnetic shielding and thermal management, protecting the integrated laser transmitter and photodiode receiver components. Compact SFP form factor (5x4x2mm) fits standard SFP slots without requiring module adapters or cage modifications. Compliance and Certifications: This module holds full compliance with IEEE 802.3ah specifications and SFF-8472 standards, ensuring interoperability with certified network equipment. Class 1 laser safety designation and FDA 21CFR 1040.10 certification confirm rigorous optical safety standards. RoHS/ELV directive compliance ensures environmental responsibility, making this suitable for sustainability-focused organizations. Applications and Use Cases: Ideal for enterprise data centers, service providers, educational institutions, and government agencies requiring reliable gigabit connectivity. Perfect for fiber-optic backbone upgrades, disaster recovery links, and redundant network paths. The 10km reach supports metro-area network deployments without regenerator requirements. Warranty and Support: 90-day limited warranty backed by technical support team. Custom brand programming available for OEM requirements. Ships from strategic US locations with free standard shipping on orders exceeding $99.
