The JBX02219 1000BASE-BX80-U SFP transceiver represents a premium solution for enterprises and service providers requiring extended-reach optical connectivity. Built to exacting standards, this module delivers reliable 1 Gigabit Ethernet transmission over single-mode fiber (SMF) with an exceptional 80-kilometer range—ideal for linking distant network sites without intermediate amplification. **Technical Specifications:** This transceiver operates using BiDi (bidirectional) technology as specified in IEEE 802.3ah extended-reach standards, allowing simultaneous transmission and reception over a single fiber strand. The module transmits at 1550nm and receives at 1490nm, leveraging wavelength-division multiplexing to maximize fiber utilization. With a 9/125 micrometer core/cladding ratio optimized for single-mode propagation, the JBX02219 achieves superior performance over conventional multimode alternatives. **Superior Design & Compatibility:** Designed as a direct replacement for the Juniper SFP-GE80KT15R14, this transceiver integrates seamlessly into existing Juniper infrastructure without configuration modifications. The robust metal case houses a precision-engineered laser transmitter and receiver assembly, protecting sensitive optics while maintaining thermal efficiency across the full 0-70°C operating range. Simplex LC/UPC connectors ensure low insertion loss and excellent return loss characteristics. **Compliance & Reliability:** Qualified to SFF-8472 specifications and extended-reach BiDi standards, the JBX02219 exceeds industry requirements. Safety certifications include Class 1 Laser, TUV, UL, and FDA 21CFR 1040.10 compliance. The module carries RoHS/ELV certification under EU directive 2002/95/EC, ensuring environmental responsibility. A comprehensive 90-day limited warranty provides additional peace of mind. **Ideal Applications:** Deploy this transceiver for metropolitan area networks connecting buildings across city distances, carrier backhaul links, disaster recovery site connectivity, and campus networks spanning multiple locations. Financial institutions, healthcare organizations, and large enterprises benefit from the extended reach eliminating costly fiber amplification infrastructure. **Custom Solutions Available:** For organizations requiring branded transceivers, custom programming is available to match corporate imaging standards. Ships quickly from US locations (Danville, CA or Beaufort, SC) with free standard shipping on orders exceeding $99. Experience enterprise-grade optical networking at competitive pricing—the JBX02219 delivers performance, reliability, and value.
