The JBX02134 1000BASE-BX10-U SFP transceiver represents an ideal solution for network administrators seeking dependable gigabit fiber connectivity. Designed to match or exceed the performance of Extreme Networks' 1G-SFP-BXU module, this transceiver provides a cost-effective alternative for expanding or maintaining existing network infrastructure. Key Technical Features: This simplex singlemode transceiver operates over 10 kilometers of standard 9/125µm singlemode fiber, making it ideal for moderate-distance campus or metro network deployments. The wavelength division multiplexing scheme—transmitting at 1310nm and receiving at 1490nm—enables bidirectional communication across a single fiber strand, optimizing infrastructure investment and reducing installation complexity. Connectivity and Compatibility: The LC/UPC connector provides excellent optical alignment and minimal insertion loss. The compact SFP (Small Form Factor Pluggable) design ensures compatibility with virtually any modern network equipment supporting standard SFP modules. This transceiver is specifically qualified for Extreme Networks platforms, making it a drop-in replacement for OEM part 1G-SFP-BXU. Reliability and Compliance: Manufactured with precision-engineered metal housings and integrated laser transmitters, this module meets rigorous safety standards including Class 1 laser certification, TUV, UL/FDA, and 21CFR 1040.10 compliance. RoHS and EU directive 2002/95/EC certification ensures environmental responsibility. Operating temperature range of 0-70°C accommodates diverse deployment scenarios from climate-controlled data centers to outdoor equipment cabinets. Operational Benefits: The 90-day limited warranty provides peace of mind, while custom brand programming options allow seamless integration into existing inventory systems. Qualified to IEEE 802.3ah and SFF-8472 standards, this transceiver guarantees interoperability and future compatibility. Applications: Ideal for enterprise networks, carrier-grade deployments, fiber-to-the-building implementations, and any application requiring reliable 1Gbps transmission over singlemode fiber infrastructure up to 10km. Shipping and Support: Free standard shipping on orders over $99 from US locations (Danville, CA and Beaufort, SC), ensuring quick deployment timelines.
