740-057315 Juniper Networks QSFP+ 40G breakout into 4x10GBASE LR up to 10km
740-057315 Overview
The 740-057315 (JNP-QSFP-4X10GE-LR) is a specialized Juniper QSFP+ optical module designed to break a single 40G port into four independent 10G connections. Each lane operates as 10GBASE-LR, supporting distances up to 10 km over single-mode fiber.Unlike standard 40G LR4 optics (which use duplex LC), this module uses an MPO-12 connector and operates with parallel optics, where 4 transmit and 4 receive fibers carry separate 10G signals.This makes it ideal for scenarios where you need to connect a 40G switch port to four 10G devices, such as servers, access switches, or aggregation layers. It is commonly used in data centers and enterprise networks for flexible port utilization.
