RQ-100G-CWDM4
100G QSFP28 CWDM4 2KM LC Optical Transceiver
FIBERWDM’s 100G QSFP28 CWDM4 is a 4x25G single-mode fiber, hot pluggable optical transceiver. FIBERWDM’s unique System On Glass TM (SOGTM) technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/ DeMUX into a small form factor package that delivers a 100 Gbps data link in a compact QSFP28 footprint.
The optical connectivity is based on two Single mode Fiber (SMF) LC connectors, one for Tx and one for Rx. The Tx and Rx each consist of 4 25GB/s CWDM channels, whose wavelengths are in the 1300nm range. The QSFP28 CWDM4 transceiver is designed for applications with a reach up to 2000m and with the use of FEC.
This transceiver is based on proprietary FIBERWDM PLC technology, using surface mounted opto-electronic devices with no free space elements. The unique design of the optical engine facilitates unparalleled compactness while maintaining Telcordia robustness.
