740-073093 Juniper Networks 40GE QSFP+ LR4 Pluggable Optics Transceiver
740-073093 Overview
The is a Juniper Networks 40GE QSFP+ LR4 pluggable optical transceiver, designed for long-distance transmission over single-mode fiber. It supports up to 10 km reach, making it ideal for data center interconnect (DCI) and enterprise backbone links.This module uses four multiplexed wavelengths in the 1310nm range (LAN-WDM) transmitted over a duplex LC fiber pair, allowing efficient long-range communication while using standard SMF cabling.Unlike breakout modules, this optic works as a single 40G link (no 4×10G split) and is commonly deployed on Juniper MX, QFX, and EX platforms.
