• The ColorChip 40G QSFP+ LR4 is a 4×10G 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 a 40Gbps data link in a compact QSFP+ 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 10Gbps CWDM channels, whose wavelengths are in the 1300nm range. The QSFP+ LR4 transceiver is designed for applications with a reach up to 10km.
  • The LR4 transceiver is based on proprietary ColorChip 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.
