Cisco QSFP-40G-ER4 Compatible 40GBASE-ER4 QSFP+ 1310nm 40km DOM Duplex LC SMF Optical Transceiver Module

40G QSFP+ ER4 transceiver

When 40G must cross the city rather than the campus, the ER4 delivers: duplex LC in, forty kilometers out, full diagnostics throughout.

Compliant with the QSFP+ MSA, IEEE 802.3bm 40GBASE-ER4 and OTU3 standards, the module multiplexes four lanes onto a duplex LC pair and reports per-channel diagnostics through I2C.

  • No external amplifiers required
  • Coded for Cisco QSFP-40G-ER4
  • Traffic-tested before dispatch
  • Serialized test documentation
  • Hot-pluggable for live systems
  • Commercial temperature operation

Typical Applications

  • Carrier access and aggregation
  • Disaster recovery links
  • Inter-city enterprise connections
