40Gbps High-Speed Connectivity

The JG661A provides 40Gbps network bandwidth through a compact QSFP+ optical transceiver. This makes it suitable for high-throughput networking environments where multiple high-speed connections need to be consolidated into a high-density switch platform.

40Gbps connectivity is particularly useful for switch-to-switch uplinks, aggregation layers, data center networks and other applications where 10Gbps connectivity may not provide sufficient bandwidth.

10km Transmission Distance

The HPE JG661A is designed for optical links extending up to 10km over compatible single-mode fiber.

This extended reach makes the module suitable for connections between network equipment located in different data center areas, buildings or facilities where short-range multimode transceivers cannot provide sufficient distance.

40GBASE-LR4 Technology

The JG661A uses 40GBASE-LR4 optical technology for 40Gbps Ethernet transmission over single-mode fiber.

LR4 transceivers use multiple optical wavelengths around the 1310nm window to achieve high-speed transmission over longer fiber distances.

1310nm Optical Wavelength

The JG661A operates around the 1310nm optical wavelength, which is commonly used for long-distance single-mode fiber communication.

The 1310nm wavelength provides suitable optical characteristics for longer fiber links and is widely used in enterprise and data center optical networking.

Single-Mode Fiber Support

The JG661A is designed for single-mode fiber (SMF) applications. Single-mode fiber is preferred for longer-distance optical links because it provides lower signal dispersion and supports significantly greater transmission distances than typical multimode fiber.

Always verify the fiber type, optical specifications and installed patch cables before deploying the transceiver.

LC Connector

The JG661A uses an LC optical connector for fiber connectivity. LC connectors are widely used in enterprise data centers and telecommunications environments because of their compact size and high port density.

Use compatible duplex single-mode LC fiber cabling when connecting the transceiver to the optical network.

QSFP+ Form Factor

The QSFP+ form factor allows 40Gbps optical connectivity in a compact, high-density module. Compared with larger optical form factors, QSFP+ helps network equipment manufacturers provide more high-speed ports within limited rack-unit space.

The JG661A is therefore suitable for high-density switch environments where 40Gbps uplink capacity is required.

Enterprise Data Center Networking

The HPE JG661A is suitable for enterprise and data center networking environments requiring reliable 40Gbps optical connectivity.

It can be deployed for network aggregation, core switching, high-speed uplinks and interconnection between compatible networking devices.

Switch Uplink Applications

40Gbps QSFP+ ports are commonly used as high-bandwidth uplinks between access, aggregation and core switches.

The 10km optical reach of the JG661A provides additional flexibility for network designs where connected switches are separated by significant physical distances.

Data Center Interconnect

The JG661A can be used for compatible data center interconnect applications where 40Gbps optical connectivity is required over single-mode fiber.

Before deployment, verify that both endpoints support the same 40G optical standard and that the optical budget is appropriate for the intended fiber distance.

High-Density Network Infrastructure

The QSFP+ form factor is particularly useful in modern data center environments where high port density is important.

A 40Gbps QSFP+ interface can provide substantially higher aggregate bandwidth than individual 10Gbps connections while maintaining a compact physical footprint.

Compatibility Considerations

The JG661A should be installed only in networking equipment that supports the relevant HPE 40Gbps QSFP+ transceiver specification.

• Compatible HPE QSFP+ port
• 40GbE support
• 40GBASE-LR4 compatibility
• Single-mode fiber infrastructure
• Compatible LC duplex fiber cable
• Appropriate optical link budget
• Compatible network-device firmware

Transceiver compatibility can depend on the switch model, firmware, optical standard and vendor coding. Always verify the exact HPE networking platform before installation.
