JTOPTICS 40G QSFP+ Transceiver 40GBASE-ER4 QSFP+ 1310nm 40km DOM Duplex LC SMF Optical Transceiver Module

QSFP+ transceiver modules are designed for use in 40 Gigabit Ethernet links over single mode fiber. They are compliant with the QSFP+ MSA and IEEE 802.3bm 40GBASE-ER4. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP+ MSA. The optical transceiver is compliant per the RoHS Directive 2011/65/EU.

JTOPTICS QSFP+ Optical Transceiver 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.
