JL306A HPE H3C Compatible 40GBASE-ER4 QSFP+ Optical Transceiver Module (SMF, 1310nm, 40km, LC, DOM)

The QSFP+ Module is designed for use in 40GBASE Ethernet throughput up to 40km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors. This transceiver is compliant with QSFP+ MSA, IEEE 802.3bm 40GBASE-ER4 and OTU3 standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP+ MSA, to allow access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable to be used in various applications, such as data centers, high-performance computing networks, enterprise core and distribution layer applications.
Note: This module has been tested on Switch built-in "ArubaOS-CX", if you want to use it with "ArubaOS" switch, we suggest initiating a test order in advance.

Certifications
Fully certified to meet strict international safety and quality standards for the industry. Go to the Compliance Center for specific certifications.
Please Note: Installing a third party transceiver does not void your network equipment warranty. Network equipment manufacturers all have guidelines stating that warranty support on their products will not be affected.
