The JBX01263 40GBASE-PSM4 QSFP+ transceiver represents enterprise-grade optical connectivity technology designed for modern high-speed network architectures. This parallel singlemode (PSM4) module enables 40 gigabit per second data transmission over extended distances, making it ideal for data center interconnections, campus networks, and carrier-grade deployments. Technical Specifications & Performance: Operating at 1310nm wavelength, this QSFP+ transceiver achieves 10km transmission distance over standard 9/125 singlemode fiber, providing superior reach compared to shorter-range alternatives. The PSM4 architecture utilizes four parallel optical lanes, each carrying 10GB of data, to achieve the aggregate 40GB throughput. This design offers excellent signal integrity and reduced latency for latency-sensitive applications. Connectivity & Compatibility: Equipped with MTP/MPO-12/APC fiber connectors, the transceiver supports standard high-density fiber optic cabling infrastructure. It is fully compatible with Ruckus E40G-QSFP-LR4-INT module specifications, enabling seamless upgrades and replacements in existing Ruckus-based network environments. The QSFP+ form factor ensures compatibility with standard network equipment ports. Robust Certifications & Compliance: This module meets or exceeds industry standards including IEEE 802.3ba for 40 Gigabit Ethernet and SFF-8436 for QSFP+ specifications. It carries Class 1 laser safety certification and FDA compliance (21CFR 1040.10), ensuring safe operation in production environments. Full RoHS and ELV compliance with EU Directive 2002/95/EC certification confirms environmental responsibility. Reliability & Support: Constructed with precision metal casings and integrated laser transmitter technology, the transceiver delivers 90-day limited warranty coverage. The module operates reliably across 0-70°C environmental conditions, suitable for both air-cooled and temperature-controlled data center deployments. Custom brand programming is available for enterprise customers requiring standardized network inventory management. Applications: Ideal for enterprise data center networks, carrier metropolitan area networks (MANs), campus backbone infrastructure, and content delivery networks requiring 40GB connectivity with extended reach. Perfect for organizations upgrading from 10GB to 40GB infrastructure while maintaining existing fiber plant investments. Shipping & Availability: Free standard shipping on orders exceeding $99, with availability from distribution centers in Danville, CA and Beaufort, SC. Manufactured in Vietnam and China using quality-assured processes, ensuring consistent performance and reliability across every unit.
