PRODUCT DETAILS

Features and applications

QSFPP-40G-LR4-C — interface and application

Juniper QSFPP-40G-LR4-C identifies the exact optical transceiver under review. Its electrical or optical interface, environmental limits and host software requirements should be reviewed together.

  • The QSFP+ interface is specified for 40 Gigabit Ethernet. Confirm the required operating mode on both ends of the link.
  • The listed reach is 10 km using SMF. Use the specification table to check any separate fiber grades or operating standards.
  • The connection uses Duplex LC PC/UPC. Include the connector polish and cable arrangement in the installation review.
  • The listed interface standard is 40GBASE-LR4; a matching mechanical connector alone does not establish interoperability.

Installation and compatibility checks

  • Match the connector, fiber type and applicable reach specification to the cable plant.
  • Check the link power budget and receiver limits; distance alone does not confirm a working optical link.
  • Confirm host port support, lane mode, software release and operating temperature before ordering.
