JTOPTICS 100G QSFP28 Transceiver 100GBASE-ER4 QSFP28 1310nm 40km DOM Duplex LC SMF Optical Transceiver Module

QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links on up to 40km of single mode fiber.  They are compliant with the QSFP28 MSA, IEEE 802.3ba 100GBASE-ER4 and IEEE 802.3bm CAUI-4. The optical transceiver is compliant per the RoHS Directive 2011/65/EU.  

QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 40km over single mode fiber (SMF) using a wavelength of 1310nm via duplex LC connectors. Taking BOX+FPC+PCBA separate design, it has great reliability, air tightness and heat dissipation performance. This transceiver is compliant with IEEE 802.3ba 100GBASE-ER4 Lite standard. Digital diagnostics functions are also available via the I2C interface, as specified by the QSFP28 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 100G telecom connections, data centers, high-performance computing networks, enterprise core and distribution layer applications.
