The JBX01806 10GBASE-ER SFP+ transceiver represents a powerful solution for extending your network reach without costly infrastructure upgrades. As a 10 Gigabit Ethernet ER (Extended Range) module, it delivers 40-kilometer transmission capabilities using 1550nm wavelength technology over single-mode fiber—significantly outperforming standard SFP+ modules in distance capability. **Key Technical Specifications:** Operating at IEEE 802.3ae standards, this transceiver provides 10 Gigabit per second data rates with full-duplex capability. The 1550nm wavelength minimizes attenuation and dispersion over long distances, while the Duplex LC/UPC connectors offer superior optical performance with ultra-polished physical contacts that reduce back-reflection. With dimensions of 5x4x2 inches and weighing minimally, it maintains the standard SFP+ form factor for seamless installation in compatible chassis. **Compatibility & Integration:** This module is engineered as a direct compatible replacement for Juniper's EX-SFP-10GE-ER transceivers, ensuring plug-and-play installation in Juniper EX series switches and networking equipment. Custom brand programming is available, allowing telecommunications carriers and service providers to maintain consistent branding across their optical infrastructure. **Quality & Compliance:** Manufactured to exacting standards with RoHS and ELV compliance, this transceiver meets global environmental regulations. Safety certifications include Class 1 Laser compliance, TUV, UL/FDA approval (21CFR 1040.10), and EU directive 2002/95/EC certification. The metal case with integrated laser transmitter provides electromagnetic shielding and thermal management for reliable long-term operation. **Operational Environment:** With an operating temperature range of 0-70°C (32-158°F), this transceiver performs reliably in diverse deployment scenarios—from climate-controlled data centers to external network cabinets. The robust construction ensures consistent performance across extended temperature variations without signal degradation. **Value Proposition:** Shipped from multiple U.S. locations (Danville, CA and Beaufort, SC) with free standard shipping on orders over $99, this module offers cost-effective network extension. The 90-day limited warranty provides peace of mind, while the widespread availability and compatibility make it an economical choice for network upgrades without vendor lock-in concerns. Ideal for telecommunications carriers, enterprises, and service providers seeking to extend 10 Gigabit connectivity over metropolitan and campus distances, this transceiver combines proven extended-range technology with Juniper ecosystem compatibility for mission-critical network applications.
