The JBX01262 40GBASE-PSM4 QSFP+ optical transceiver represents a premium solution for organizations requiring reliable, high-speed network connectivity. As part of the 40GB QSFP+ module category, this transceiver is engineered to deliver exceptional performance in demanding network environments. **Technical Specifications & Performance** This module supports 40GB data transmission over distances up to 10 kilometers via standard singlemode fiber (SMF) with 9/125μm core specifications. Operating at 1310nm wavelength, it provides optimal signal propagation characteristics for enterprise installations. The QSFP+ form factor ensures compatibility with modern switching infrastructure, while MTP/MPO connectors facilitate high-density fiber management in colocation facilities and data centers. **Compatibility & Integration** The JBX01262 is explicitly designed as a compatible replacement for Palo Alto Networks' PAN-QSFP-40GBASE-PLR4 modules. This compatibility extends functionality to security appliances and network appliances requiring 40GBASE-PSM4 optical connectivity. The plug-and-play design minimizes deployment time while maintaining network reliability. **Quality & Compliance Standards** Manufactured in Vietnam and China to stringent quality standards, this transceiver meets IEEE 802.3ba specifications and SFF-8436 form factor requirements. The unit carries full RoHS/ELV directive compliance (EU 2002/95/EC) and includes Class 1 laser certification per LN #50 7/2001. Additionally, it holds TUV and UL/FDA approval under 21CFR 1040.10, ensuring safe operation in all deployment scenarios. **Durability & Support** Encased in a protective metal housing with integrated laser transmitter technology, the module operates reliably across standard temperature ranges (0-70°C). The 90-day limited warranty provides confidence in product reliability, while custom brand programming options accommodate enterprise branding requirements. Backed by free standard shipping on orders exceeding $99, this solution delivers exceptional value for network upgrades and expansion projects. **Applications** Ideal for organizations implementing Palo Alto Networks security infrastructure, campus network upgrades, disaster recovery implementations, and high-speed data center interconnections requiring 10km reach capabilities over singlemode fiber.
