QSFP CWDM Transceivers S40-QP-LR4-D

QSFP CWDM Transceivers S40-QP-LR4-D

The S40-QP-LR4-10-D is designed to operate over single-mode fiber system using 4x10G CWDM channel in 1310 band and links up to 10km. The module converts 4 inputs channel of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data

  • High Channel Capacity: 40 Gbps per module
  • CWDM 1271, 1291, 1311, 1331 nm wavelengths
  • Up to 11.1Gbps Data rate per channel
  • Maximum link length of 10 Km
  • Electrically hot-pluggable
  • Digital diagnostic Monitoring interface
  • Compliant with QSFP+ MSA with LC connector
  • Case operating temperature range:0°C to 70°C
  • Power dissipation < 1.5 W


Digital Diagnostics Functions
