The JBX02406 25GBASE-BX40-D SFP28 Transceiver represents a cost-effective solution for extending network connectivity across long distances while maintaining high-speed performance. Engineered to IEEE 802.3by specifications, this optical module delivers consistent 25 Gbps throughput ideal for modern data center, campus, and metropolitan area network (MAN) applications. ## Technical Specifications This transceiver operates using a simplex LC/UPC fiber connection, transmitting data over a single strand of 9/125 micrometers singlemode fiber. The 40-kilometer transmission distance makes it suitable for regional network expansion without requiring expensive regeneration equipment. The compact SFP28 form factor ensures compatibility with space-constrained networking environments while maintaining reliability. ## Performance & Compatibility Specifically designed for Juniper networks, the JBX02406 replaces the OEM part number SFP-25G-BX40D-I without requiring firmware modifications. The module qualifies under IEEE 802.3by standards and meets SFF-8402 and SFF-8472 specifications for industry-standard interoperability. Whether upgrading existing Juniper deployments or building new infrastructure, this transceiver provides reliable, proven compatibility. ## Safety & Compliance This Class 1 laser product meets stringent safety standards including FDA 21CFR 1040.10, UL, and TUV certifications. The RoHS-compliant design with metal case construction ensures durability and environmental responsibility. Operating temperatures from -40 to 85°C accommodate diverse deployment scenarios from climate-controlled data centers to outdoor network cabinets. ## Deployment Advantages The 40km reach eliminates intermediate amplification for most campus and regional connections, reducing infrastructure costs. Simplex operation reduces fiber installation requirements compared to duplex modules, lowering overall project expenses. Custom brand programming availability allows integration into enterprise inventory management systems. ## Value Proposition With free standard shipping on orders exceeding $99, direct US fulfillment from California and South Carolina locations, and 90-day warranty coverage, this transceiver delivers enterprise-grade reliability at competitive pricing. Suitable for IT professionals, network engineers, and system integrators requiring certified, high-performance optical connectivity solutions.
