The JBX01771 10GBASE-BX80-U SFP+ Transceiver Module represents a cost-effective solution for organizations requiring extended-range optical connectivity in their network infrastructure. This single-mode fiber transceiver is engineered to deliver reliable 10 gigabit-per-second data transmission over distances up to 80 kilometers, making it ideal for metropolitan area networks (MANs) and wide area network (WAN) applications. **Technical Specifications & Performance:** This optical transceiver operates according to IEEE 802.3ae standards and complies with SFF-8431 and SFF-8472 industry specifications. The module features a 9/125 single-mode fiber core with simplex LC/UPC connectivity, eliminating the need for separate transmit and receive fibers. The integrated laser transmitter and metal housing provide durability and optimal signal integrity over long distances. **Compatibility & Integration:** The JBX01771 serves as a direct replacement for Cisco's SFP-10G-BX-U80 transceiver, ensuring seamless integration with existing Cisco networking equipment. This compatibility eliminates costly infrastructure redesigns and streamlines deployment procedures. The module is available with custom brand programming options for organizations requiring proprietary identification. **Safety & Environmental Compliance:** As a Class 1 laser device, this transceiver meets stringent safety standards including TUV certification, UL approval, and FDA 21CFR 1040.10 compliance. Full RoHS and ELV directive adherence (EU 2002/95/EC) ensures environmentally responsible operation without hazardous materials. The operating temperature range of 0-70°C accommodates most data center and network facility environments. **Advantages Over Alternatives:** Unlike longer-distance transceivers, the 80km BX80-U model provides optimal cost-efficiency for regional network expansion without overspecifying capabilities. The simplex design reduces cabling complexity compared to duplex solutions, while the 10GB throughput supports modern bandwidth-intensive applications and future network growth. **Shipping & Support:** Ships from convenient U.S. locations (Danville, CA and Beaufort, SC) with complimentary standard shipping on orders exceeding $99. Backed by a 90-day limited warranty ensuring customer satisfaction and peace of mind. Ideal for telecommunications providers, enterprise data centers, educational institutions, and government networks requiring reliable, standards-compliant optical connectivity solutions.
