40G QSFP+ LR4 Optical Transceiver – 10km LC SMF

SVNK 40G QSFP+ LR4 Optical Transceiver – 10km Single-Mode Fiber

The SVNK 40G QSFP+ LR4 optical transceiver is designed for 40GBASE-LR4 Ethernet applications, delivering reliable 40 Gigabit Ethernet connectivity over single-mode fiber (SMF) up to 10 km. Operating at a nominal wavelength of 1310 nm, this module integrates four uncooled CWDM transmitters to multiplex four 10Gb/s lanes into a single duplex LC fiber pair, significantly reducing fiber infrastructure requirements.

This transceiver is fully compliant with QSFP+ MSA (SFF-8436), IEEE 802.3ba/802.3bm 40GBASE-LR4 standards, and CMIS 4.0 management interface, ensuring broad interoperability across leading switches, routers, servers, and network platforms. Built-in Digital Optical Monitoring (DOM) via I²C allows real-time monitoring of temperature, voltage, transmit power, and receive power for proactive network management.

With its hot-pluggable form factor, low power consumption, and compact design, the SVNK 40G LR4 module enables easy deployment and rapid upgrades in data centers, enterprise networks, telecom backbones, and cloud environments.
