- 1310nm wavelength for optimal transmission
- Low bit-error rate for data integrity
High-Density Connectivity
The QSFP+ form factor provides a compact footprint, allowing for high port density in switches and routers. This maximizes rack space efficiency while delivering 40 Gbps throughput per port.
- QSFP+ hot-pluggable design
- Single-port configuration
- Supports high-speed aggregation links
Deployment / Use Cases
This transceiver is suited for core switching, spine-leaf architectures, and high-performance computing clusters where 40 Gbps uplinks are required. It connects switches to routers, servers to top-of-rack switches, or aggregates multiple 10 Gbps links into a 40 Gbps backbone.
Common deployment scenarios include data center fabric extensions, enterprise network backbones, and service provider edge networks. The 10 km reach supports connections between buildings or across campuses without intermediate equipment.
Data Center Interconnect
Use this transceiver to link data center switches over single-mode fiber, providing high-bandwidth connectivity for server-to-server communication and storage area networks.
Enterprise Backbone
Deploy in enterprise core switches to aggregate traffic from access layers, ensuring sufficient bandwidth for voice, video, and data applications across large facilities.
Physical Profile
The transceiver measures 4.80 inches (122 mm) in width and weighs approximately 1.73 ounces (49 grams). Its compact, lightweight design facilitates easy installation and minimizes thermal load in densely populated chassis.

FAQ
What is the maximum distance this transceiver can support?
This HPE transceiver supports a maximum reach of 10 kilometers over single-mode fiber optic cabling. This distance is achieved using 1310nm wavelength optics and the 40GBase-LR4 standard, making it suitable for connections between buildings or across campus networks without signal degradation.
What type of fiber optic cable is compatible with this transceiver?
The transceiver is designed for use with single-mode fiber optic cables. It requires LC connector interfaces, which are standard for high-density optical connections. Single-mode fiber provides lower attenuation and supports longer distances compared to multimode fiber, ideal for the 10 km reach of this module.
What networking standard does this transceiver use?
This transceiver operates on the 40GBase-LR4 Ethernet standard, which aggregates four lanes of 10 Gbps each to deliver a total data rate of 40 Gbps. It is specifically engineered for long-reach applications over single-mode fiber, ensuring compatibility with 40 Gigabit Ethernet switches and routers that support the QSFP+ form factor.
Is this transceiver hot-pluggable?
Yes, this QSFP+ transceiver is hot-pluggable, allowing it to be installed or removed without powering down the networking equipment. This feature minimizes downtime during maintenance or upgrades and supports flexible network reconfiguration in live environments.
