10 Gigabit Ethernet is no longer enough for the increasing need for high speed transmission with applications like Big Data, Cloud and Internet of Things being introduced in a variety of industries. Transmission network migration to 40G has already been the industry consensus. Juniper QSFP+ (quad small form-factor pluggable plus) modules offer you a wide variety of connectivity options for your 40 Gigabit Ethernet applications. This article introduces several kinds of Juniper 40GBASE QSFP+ modules to you.

Juniper is a leading provider of optical and copper network equipment including all kinds of optical transceivers and cables. Juniper QSFP+ is a Multi-Source Agreement (MSA) standard for high speed application, providing four channels of data in one pluggable interface. Each channel is capable of transferring data at 10Gbps and supports a total of 40Gbps. Juniper 40G QSFP+ transceivers are QSFP+ MSA and SFF-8436 compatible and are electrically hot-pluggable, with four independently addressable transmit and receive channels. Juniper QSFP+ transceivers are well tested on Juniper switch to ensure optimal signal integrity and the best end-to-end performance. The following part will introduce three types of Juniper QSFP+ modules.

Juniper JNP-QSFP-40G-LR4 40GBASE-LR4 QSFP+ transceiver supports link lengths of up to 10km over single mode fiber with duplex LC connectors. 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed in the device. It is compliant with the QSFP+ MSA and IEEE 802.3ba, and RoHS-6 compliant with built-in DDM interface. Juniper JNP-QSFP-40G-LR4 QSFP+ module can also be used in a 4x10G module for interoperability with 10GBASE-LR interfaces. The image below shows a Juniper JNP-QSFP-40G-LR4 compatible 40GBASE-LR4 QSFP+ transceiver.

Juniper JNP-QSFP-40G-LX4 40GBASE-LX4 QSFP+ transceiver supports link lengths of up to 300m on OM3 multi-mode fiber (MMF). It is compliant with QSFP+ MSA, RoHS, and QDR/DDR Infiniband data rates. It is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ MSA. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The image below shows a Juniper JNP-QSFP-40G-LX4 40GBASE-LX4 QSFP+ transceiver.

Juniper QFX-QSFP-40G-SR4 40GBASE-SR4 QSFP+ transceiver supports link lengths of 100m on OM3 multimode fibers and 150m and OM4 multimode fibers, operating at a wavelength of 850nm. The image below shows a Juniper QFX-QSFP-40G-SR4 compatible 40GBASE-SR4 QSFP+ transceiver. It enables high-bandwidth 40G optical links over fiber terminated with MPO/MTP multifiber connectors and can also be used in a 4x10G module for interoperability with 10GBASE-SR interfaces. It is the standard MSA multi-mode transceiver for 10Gigabit Ethernet and 40Gigabit Ethernet with MPO connector.
