The JBX01425 is a premium 100GBASE-ER4-Lite QSFP28 optical transceiver module designed for telecommunications and data center infrastructures requiring high-speed, long-distance connectivity. Engineered to deliver 100 gigabits per second of data transmission over 40 kilometers of standard singlemode fiber, this module represents an optimal balance between performance, distance capability, and cost-effectiveness. ## Technical Specifications This transceiver operates at 100GB data rates using the ER4-Lite protocol, which extends transmission distances to 40km—significantly beyond standard short-reach modules. The 9/125 micrometer singlemode fiber core ensures minimal signal degradation and supports standard telecommunications infrastructure. The module features industry-standard Duplex LC/UPC connectors, providing reliable, low-loss optical connections with excellent return loss characteristics. ## Compatibility & Standards Compliance The JBX01425 is fully compatible with Juniper networking equipment, specifically replacing the OEM Juniper JNP-QSFP-100G-ER4L module. It meets stringent IEEE 802.3bm and QSFP28 Multi-Source Agreement (MSA) specifications, ensuring seamless integration with qualified network equipment. The module has been qualified to SFF-8665 standards for enhanced reliability and interoperability. ## Safety & Environmental Compliance This optical transceiver maintains rigorous safety certifications including Class 1 Laser classification, UL/FDA approval (21CFR 1040.10), and TUV certification. The module is fully RoHS and ELV compliant, adhering to EU directive 2002/95/EC, making it suitable for environmentally conscious organizations. ## Performance Features Designed with a metal case construction incorporating advanced laser transmitter technology, the JBX01425 operates reliably across a wide temperature range (0°C to 70°C / 32°F to 158°F). Its compact dimensions (5.0" × 4.0" × 2.0") enable deployment in high-density switching environments without requiring major infrastructure modifications. ## Applications Ideal for metropolitan area networks (MANs), campus backbone interconnections, and data center expansion projects where 40km reach without regeneration is required. The module's extended distance capability eliminates the need for expensive signal regeneration equipment, reducing total cost of ownership. ## Support & Service Every unit includes a 90-day limited warranty and custom brand programming services are available. Orders ship free from multiple U.S. locations (Danville, CA and Beaufort, SC) for standard shipping on purchases exceeding $99.
