Rapide II™ 40GBase-ER4 QSFP+ 1310nm 40km LC Transceiver Module

  • Hot pluggable QSFP+ form factor
  • Maximum link length of 40m on Singlemode Fiber (SMF)
  • Central wavelengths of the 4 CWDM channels are 1271, 1291, 1311, and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2
  • Converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals, multiplexes them into a single channel for 40Gb/s optical transmission, and reversely de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data on the receiver side.
  • Contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface
  • Commercial operating case temperature range: 0ºC to 70ºC
  • Compatible with Arista, Cisco, HPE, Juniper, and standard switches
  • Leadtime 3-4 weeks for backorders
