The AddOn Juniper Networks Compatible EX-SFP-10G-BX-U-40 is a high-performance SFP+ transceiver engineered for demanding 10-Gigabit Ethernet applications over extended distances. Utilizing advanced Bidirectional (BiDi) technology, this module transmits at 1270nm and receives at 1330nm, enabling simultaneous data transmission over a single strand of single-mode fiber up to 40 km (approximately 24.8 miles). This innovative approach effectively doubles your fiber capacity without the expense of installing additional cabling, making it an ideal solution for fiber-constrained network environments. The transceiver delivers reliable 10.3 Gbps data rates through a simplex LC connector and includes Digital Optical Monitoring (DOM) support for real-time performance diagnostics. Built to withstand commercial operating temperatures from 0°C to 70°C (32°F to 158°F), it ensures consistent performance in various deployment scenarios. This is an Upstream module that must be paired with the corresponding Downstream module (EX-SFP-10G-BX-D-40) at the opposite end of the fiber link to establish proper wavelength alignment and functional connectivity. TAA Compliant and suitable for long-distance network infrastructure deployments.
