The JBX02200 1000BASE-BX40-U SFP transceiver represents a robust solution for organizations requiring extended-range optical networking capabilities. Designed to transmit low-voltage network signals over single-mode fiber at distances up to 40 kilometers, this module excels in long-haul network deployments where standard transceivers fall short. **Technical Specifications:** Operating at 1Gbps data rates with 9/125 single-mode fiber compatibility, the JBX02200 utilizes bidirectional wavelengths (1310/1550nm) for simultaneous transmission and reception on a single fiber strand. The simplex LC/UPC connector design ensures precise alignment and minimal insertion loss, while the compact SFP form factor (5x4x2 dimensions) fits seamlessly into standard SFP ports. **Key Features & Benefits:** This module delivers exceptional value through Cisco GLC-BX35-U40 compatibility, eliminating costly proprietary solutions. Its extended-reach capability surpasses IEEE 802.3ah standards per SFF-8472 specifications, enabling longer network spans with reliable performance. The metal case construction with integrated laser transmitter provides durability in demanding network environments. **Compliance & Safety:** Fully certified to Class 1 Laser safety standards and qualified to TUV, UL, and FDA (21CFR 1040.10) requirements, this transceiver meets the highest industry safety protocols. RoHS and ELV directive compliance ensures environmental responsibility. **Operational Reliability:** With operating temperatures spanning 0-70°C (32-158°F), the JBX02200 maintains consistent performance across diverse climates. Custom brand programming is available for OEM applications, while the 90-day limited warranty provides peace of mind. **Ideal Applications:** Perfect for ISPs, telecommunications providers, data center interconnections, campus networks, and enterprise WAN deployments requiring cost-effective, reliable long-distance fiber connectivity.
