The ColorChip QSFP28 LR4 is a 4x28G single-mode fiber, hot pluggable optical transceiver. ColorChip’s unique SystemOnGlassTM (SOGTM) technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/ DeMUX into a small form factor package that delivers up to 112 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 28Gbps LAN-WDM channels, whose wavelengths are in the 1300nm range. The QSFP28 LR4 transceiver is designed for applications with a reach up to 10Km.
Compliant with the QSFP28 MSA Technical Specifications.
Supports 103.1Gbps and 112Gbps data rates.
