The JBX02308 is a premium 1000BASE-ZX SFP transceiver engineered for enterprises and service providers requiring extended-range gigabit Ethernet connectivity. This dual-fiber transceiver operates at 1550nm wavelength and supports transmission distances up to 80km over standard single-mode fiber, making it ideal for metropolitan area networks (MANs) and wide area network (WAN) backbone connections without requiring optical amplification. Key Features: The module features a compact SFP form factor compatible with virtually all SFP-enabled network equipment. Its duplex LC/UPC connectors provide reliable, low-loss optical mating with standard industry connectors. The 9/125 micron single-mode fiber core ensures excellent signal integrity over long distances while maintaining cost-effectiveness compared to premium long-reach alternatives. Technical Excellence: Fully qualified to IEEE 802.3z specifications, this transceiver delivers consistent 1 Gbps data rates with minimal latency. The integrated laser transmitter and receiver architecture provides superior thermal stability across the 0-70°C operating temperature range. Advanced SFF-8472 diagnostics support real-time monitoring of optical power, temperature, and voltage parameters. Compliance & Reliability: Class 1 laser certification ensures safe operation in managed environments. Full RoHS/ELV compliance meets EU directive 2002/95/EC requirements for environmentally responsible networking. The rugged metal case protects internal components from electromagnetic interference and physical damage. Each unit includes a 90-day limited warranty. Cisco Compatibility: This module directly replaces Cisco GLC-ZX-SM and MA-SFP-1GB-LX80 transceivers, offering significant cost savings without sacrificing performance or reliability. Custom brand programming is available for OEM integration requirements. Applications: Ideal for campus network extensions, disaster recovery site links, carrier backbone networks, and metropolitan fiber deployments. Cost-effective solution for organizations seeking extended-range connectivity without costly optical amplification infrastructure. Shipping & Support: Qualifies for free standard shipping on orders over $99 from U.S. locations (Danville, CA and Beaufort, SC). Technical support available for installation and configuration assistance.
