100G QSFP28 CWDM4 Optical Transceiver – 2km LC SMF

SVNK 100G QSFP28 4CWDM Optical Transceiver (2 km, SMF)

The SVNK 100G QSFP28 4CWDM Optical Transceiver is a high-performance optical module designed for next-generation optical communication systems and fully compliant with the 100G 4CWDM-10 MSA. The module converts four 25G electrical input channels into four CWDM optical wavelengths, which are multiplexed into a single 100G optical signal for transmission over single-mode fiber (SMF). On the receiver side, the incoming 100G optical signal is demultiplexed back into four CWDM channels and converted into four high-speed electrical outputs.

The transmitter integrates high-performance cooled CWDM DFB lasers, delivering excellent wavelength stability, low noise, and superior optical output power. Combined with high-sensitivity PIN receivers and advanced signal conditioning, the module ensures reliable high-speed transmission with low bit-error rates over distances of up to 2 km, making it ideal for data center interconnects and enterprise networks.

Housed in a compact, hot-pluggable QSFP28 form factor, the transceiver supports internal CDR (Clock and Data Recovery) on both transmit and receive channels, with optional CDR bypass. This enables excellent signal integrity, enhanced jitter tolerance, and flexible system design.
