100G QSFP28 LR4 Optical Transceiver – 10km LC SMF

SVNK 100G QSFP28 4WDM-10 Optical Transceiver (10 km, SMF)

The SVNK 100G QSFP28 4WDM-10 Optical Transceiver is a high-performance optical module designed for next-generation optical communication systems and compliant with the 100G 4WDM-10 MSA. The module converts four 25G electrical input channels into four CWDM optical wavelengths, multiplexes them into a single optical signal, and transmits 100 Gb/s data over single-mode fiber (SMF). On the receive side, the incoming optical signal is demultiplexed into four CWDM wavelengths and converted back into high-speed electrical outputs.

The transmitter integrates high-performance cooled CWDM DFB lasers, delivering excellent wavelength stability, strong optical output power, and superior signal integrity. Combined with high-sensitivity PIN ROSA receivers and advanced signal conditioning, the module ensures stable, low-error 100G transmission over distances of up to 10 km, making it ideal for enterprise and data-center interconnect applications.

Housed in a compact, hot-pluggable QSFP28 form factor, the transceiver supports internal Clock and Data Recovery (CDR) on both transmit and receive channels, with optional CDR bypass, enabling excellent jitter tolerance, system flexibility, and wide platform interoperability.
