The JBX01673 is a premium 10GBASE-BX10-D SFP+ optical transceiver engineered for enterprise-grade network deployments requiring long-reach singlemode fiber connectivity. Operating at 10 Gigabits per second over distances up to 10 kilometers, this module combines performance with affordability through its simplex LC/UPC fiber configuration. **Technical Specifications:** This transceiver utilizes 9/125 micron singlemode fiber for optimal signal integrity and minimal attenuation. The simplex configuration employs a single fiber strand, reducing deployment costs while maintaining full 10G throughput. Housed in a compact 5x4x2mm metal case with integrated laser transmitter technology, the module delivers consistent performance across operating temperatures from 0 to 70°C (32 to 158°F). **Compatibility & Integration:** Designed as a direct replacement for Arista SFP-10G-BX-D and SFP-10G-ERLBD-D modules, this transceiver integrates seamlessly into existing Arista ecosystems. Full compliance with IEEE 802.3ae standards, SFF-8431, and SFF-8472 specifications ensures interoperability with industry-standard equipment. The module supports custom brand programming, allowing OEM resellers to maintain their own product branding. **Safety & Compliance:** Comprehensive certifications include Class 1 Laser safety, UL/FDA approval (21CFR 1040.10), TUV certification, and RoHS/ELV directive compliance. These credentials guarantee safe operation in diverse network environments while meeting stringent environmental regulations. **Ideal Applications:** Perfect for data center interconnects, campus networks, metropolitan area networks (MANs), and enterprise backbone applications. The 10km range accommodates moderate-distance campus deployments without requiring expensive long-reach optics. Simplex operation suits unidirectional transmission scenarios, reducing overall network costs. **Warranty & Support:** Backed by a 90-day limited warranty with fast domestic shipping from Danville, CA and Beaufort, SC locations. Free standard shipping applies to orders exceeding $99, making bulk purchases particularly economical.
