The JBX02048 1000BASE-SX SFP transceiver is a versatile optical module engineered to deliver reliable, high-speed gigabit Ethernet connectivity for enterprise networks, data centers, and telecommunications infrastructure. Operating at the 850nm wavelength standard for multimode fiber applications, this transceiver provides exceptional performance and compatibility with existing Brocade networking equipment. **Technical Specifications:** This SFP (Small Form-Factor Pluggable) transceiver supports 1000BASE-SX connections with a maximum transmission distance of 550 meters over OM2 multimode fiber—the industry standard for many existing installations. The duplex LC/UPC connectors ensure precise optical alignment and minimal signal loss. With a compact form factor measuring 5x4x2 inches and weighing mere ounces, it integrates seamlessly into SFP-equipped network switches and routers. **Performance & Compatibility:** Fully compliant with IEEE 802.3z and SFF-8472 standards, the JBX02048 delivers 1GB data rates with consistent, reliable operation. It's specifically designed as a drop-in replacement for Brocade E1MG-SX-OM-T modules, making upgrades and replacements straightforward without requiring firmware changes or reconfiguration. **Safety & Compliance:** This transceiver meets stringent safety and environmental standards, including Class 1 Laser certification, FDA compliance (21CFR 1040.10), TUV and UL certifications, and RoHS/ELV directives. The metal case with integrated laser transmitter provides durability and optimal thermal management across operating temperatures from -40°C to 85°C. **Applications & Use Cases:** Ideal for connecting switches within the same building or campus, connecting servers to core switches, or establishing backup connectivity in redundant network configurations. The 550-meter range covers most office buildings and campuses, while multimode fiber compatibility makes it cost-effective for short- to medium-distance deployments. **Warranty & Support:** Backed by a 90-day limited warranty and available with custom brand programming for OEM customers. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99. Whether you're upgrading legacy Brocade systems, expanding network capacity, or establishing redundant connections, the JBX02048 offers proven reliability and superior value for gigabit Ethernet infrastructure.
