The Juniper QSFPP-40GBASE-ER4 is a QSFP+ transceiver module from Juniper Networks. It supports 40 Gbps transmission speed over single-mode fiber (SMF) using a wavelength of 1310 nm, with distances up to 40 km.
This transceiver operates on four channels and connects via LC duplex connectors for long-range data communication in standard network equipment supporting the QSFP+ form factor. Compatible with various Juniper switches and routers, it uses direct modulation through CWDM optics across four distinct lanes aggregated into one output stream.
