The JBX02027 1000BASE-T SFP Transceiver is a high-performance networking solution designed for organizations leveraging Juniper EX series infrastructure. This transceiver module operates at 1 Gigabit per second, delivering fast, reliable Ethernet connectivity over standard copper RJ45 cabling infrastructure. Supporting transmission distances up to 100 meters, it enables flexible network topology designs while maintaining compatibility with existing twisted-pair cabling. Engineered as a direct replacement for Juniper OEM part numbers EX-SFP-1GE-T-ET and SRX-SFP-1GE-T-ET, this module integrates seamlessly into Juniper EX and SRX series switches and routers without firmware modifications. Its RJ45 connector eliminates the need for costly fiber infrastructure, making it an economical choice for network expansion and upgrades. Built with premium materials including a metal case and printed circuit board, this transceiver ensures long-term durability and signal integrity. The compact 5 x 4 x 2-inch form factor fits easily into SFP slots without occupying additional space. Full compliance with IEEE 802.3ab specifications guarantees interoperability with standard Gigabit Ethernet networks. The JBX02027 exceeds industry safety and environmental standards, holding RoHS, TUV, and UL certifications. It complies with EU Directive 2002/95/EC (RoHS) for hazardous substance restrictions. Operating reliably across extended temperature ranges from -40 to 85°C (-40 to 185°F), this module performs consistently in diverse deployment environments. Custom brand programming is available for organizations requiring OEM labeling or specific configuration requirements. The transceiver includes a 90-day limited warranty, and qualified orders qualify for free standard shipping from our California and South Carolina distribution centers. Whether upgrading existing Juniper infrastructure or deploying new network segments, the JBX02027 delivers enterprise-grade performance at competitive pricing.
