The JBX02299 1000BASE-ZX SFP transceiver represents a cost-effective solution for enterprises requiring extended-reach Gigabit Ethernet connectivity over singlemode fiber infrastructure. This optical transceiver module operates at 1550nm wavelength, enabling transmission distances up to 70 kilometers without signal degradation—significantly exceeding standard 1000BASE-LX capabilities. This extended range makes it particularly valuable for organizations connecting geographically dispersed facilities, implementing disaster recovery networks, or expanding data center footprints across metropolitan areas. Key Technical Features: The transceiver utilizes 9/125 micron singlemode fiber with duplex LC/UPC connectors, providing industry-standard interfaces that integrate seamlessly with existing fiber infrastructure. The SFP form factor enables hot-swappable installation in any compatible network equipment, supporting quick upgrades without system downtime. Built to IEEE 802.3z and SFF-8472 standards, this module delivers consistent 1 Gigabit per second performance with reliable bidirectional communication. Quality and Compliance: Manufactured with precision-engineered laser transmission components housed in a protective metal case, the JBX02299 undergoes rigorous testing to meet Class 1 laser safety standards, TÜV certification, UL/FDA compliance (21CFR 1040.10), and RoHS/ELV environmental directives. These certifications ensure safe operation in professional network environments while meeting international regulatory requirements. Compatibility and Integration: Purpose-built for Extreme Networks infrastructure, this transceiver directly replaces OEM part numbers 1G-SFP-LHA-OM-T, 10053H, and I-MGBIC-GZX. The module accommodates custom brand programming, allowing organizations to maintain consistent branding across their network equipment inventory. Operational Reliability: Designed for demanding network environments, the transceiver operates reliably across extended temperature ranges (-40°C to 85°C), making it suitable for both climate-controlled data centers and outdoor cabinet installations. The 90-day limited warranty provides confidence in product quality and performance. Applications: Ideal for enterprise WAN connections, ISP backbone networks, metropolitan area networks (MANs), and multi-site campus interconnections requiring high-reliability, extended-distance fiber transmission without the cost of router-based solutions. Shipping and Support: Orders over $99 qualify for free standard shipping from conveniently located fulfillment centers in California and South Carolina, ensuring rapid delivery and reliable service.
