Description

This Juniper QSFP+ optical transceiver breaks out a single 40G port into four 10GBASE-LR channels over parallel single-mode fibre. It reaches up to 10 km using an MPO-12 APC connector and is the standard-temperature (0 to 70 °C) variant designed for Juniper routing platforms. Digital optical monitoring provides real-time visibility of operating parameters, making it suited to high-density 10G aggregation from 40G ports.

FAQs

Q: What does this transceiver do?
A: It is a 40G QSFP+ module that can break out into four independent 10GBASE-LR channels over parallel single-mode fibre, allowing one 40G port to serve four 10G links.

A: It uses an MPO-12 APC connector with single-mode fibre (SMF), supporting distances of up to 10 km.

Q: Does it support digital optical monitoring?
A: Yes, it supports Digital Optical Monitoring (DOM) so operating parameters can be monitored in real time.

Q: What operating temperature range does this variant cover?
A: This is the standard-temperature variant, rated for 0 to 70 °C.

Q: Can this module be used for 40G to 40G links?
A: It is designed as a breakout module into 4x10GBASE-LR channels, so it suits 40G-to-4x10G deployments rather than a single native 40G link.
