The JBX02135 1000BASE-BX10-U SFP transceiver represents a premium solution for businesses seeking dependable optical networking infrastructure. Engineered to deliver consistent gigabit-speed performance, this single-mode fiber transceiver excels in medium-distance network scenarios where reliability and signal integrity are paramount. **Technical Specifications:** This optical transceiver operates using 1000BASE-BX10-U technology, transmitting data at 1GB speeds over distances up to 10 kilometers via single-mode fiber (SMF). The module uses simplex LC/UPC connectors—industry-standard interfaces that ensure secure, aligned connections with minimal signal loss. It operates on dual wavelengths: 1310nm for transmission and 1490nm for reception (or vice versa, depending on configuration), enabling full-duplex communication over a single fiber strand. The transceiver features a robust metal case housing an integrated laser transmitter, providing both durability and reliable optical signal generation. Its compact dimensions (5.0 x 4.0 x 2.0 inches) allow seamless integration into existing network infrastructure without space constraints. **Compliance & Safety:** Fully certified to IEEE 802.3ah standards and SFF-8472 specifications, this module guarantees interoperability across diverse networking environments. Safety certifications include Class 1 Laser classification, ensuring eye-safe operation under normal conditions. Additional certifications—TUV, UL, and FDA 21CFR 1040.10—demonstrate compliance with international safety and environmental regulations. RoHS/ELV directive compliance eliminates hazardous materials, making it suitable for environmentally conscious organizations. **Compatibility & Integration:** The JBX02135 is manufactured to replace Extreme Networks AA1419069 and maintains full compatibility with Extreme Networks infrastructure. Custom brand programming is available for OEM requirements and white-label applications. **Operating Conditions:** With an operating temperature range of 0-70°C (32-158°F), this transceiver performs reliably across diverse climatic conditions, from controlled data centers to less-regulated network closets. **Value Proposition:** Invest with confidence: every unit includes a 90-day limited warranty, backed by Free Standard Shipping on orders exceeding $99.
