Product Description
This Juniper QSFP+ transceiver module allows a single QSFP+ port to split into four separate 10Gb/s 10GBase-LR connections over single-mode fiber. It’s commonly used in data centers and enterprise networks where high bandwidth and long reach are required over optical fiber. Built for network engineers and IT professionals managing high-speed fiber links, it delivers reliable connectivity for aggregation or distribution layers in network infrastructure. Often found in Juniper switches and routers, it enables flexible and efficient use of existing fiber cabling. Key Features Breaks out one 40Gb/s QSFP+ port into four independent 10Gb/s channels Supports up to 10km reach over single-mode fiber using 1310nm wavelength MPO-12 APC connector type for low insertion loss and back reflection Compatible with standard 10GBase-LR protocols for broad interoperability Designed for use in high-density network environments to maximize port utilization This module is typically deployed in large campus networks or data center environments where fiber runs require distances beyond short-range optics. It helps network operators scale bandwidth without re-cabling by leveraging breakout capabilities. The module’s robust performance aids in maintaining stable long-distance connections for critical data transmission.

Use Cases
The 740-057315 Juniper 4x10Gb/s QSFP+ 10GBase-LR MPO-12 APC Transceiver is ideal for network environments requiring long-distance, high-bandwidth connectivity over single-mode fiber. It benefits data center architects, enterprise IT teams, and service providers focused on optimizing port density while maintaining extended reach across campus and metropolitan area networks. How It's Used: Breaking out a 40Gbps QSFP+ uplink into four separate 10Gbps links within large-scale data center spine-leaf architectures. Extending fiber connectivity between enterprise campus buildings up to 10 km apart without sacrificing signal integrity. Supporting high-capacity storage area networks (SANs) that demand reliable 10GBase-LR interfaces over single-mode fibers. Enabling service providers to aggregate multiple 10G customer connections on a single optical port for efficient metro network deployment. Facilitating edge computing sites requiring scalable multi-channel fiber links with precise optical alignment via MPO-12 APC connectors. This transceiver module streamlines network scalability by consolidating multiple 10G channels into a single QSFP+ port, reducing cabling complexity and improving fiber management. Its compatibility with single-mode fiber infrastructures supports robust, long-distance communication critical for maintaining consistent network performance across distributed environments.
