As the ever-growing demands for higher speed data rates, transmission network migration to 40G has already been the industry consensus. 40G products have currently been mass produced. Mellanox QSFP+ (quad small form-factor pluggable plus) modules offer you a wide variety of connectivity options for your 40 Gigabit Ethernet applications. This article gives a basic introduction to Mellanox 40GBASE QSFP+ modules.

Mellanox is a leading provider of optical network equipment. Mellanox 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. Mellanox 40G QSFP+ transceivers are SFF-8436 compatible and are electrically hot-pluggable, with four independently addressable transmit and receive channels. Mellanox QSFP+ transceivers are well tested on Mellanox switch to ensure optimal signal integrity and the best end-to-end performance. Two types of Mellanox QSFP+ modules are introduced in the following text.

Mellanox MC2210411-SR4 40GBASE-SR4 QSFP+ transceiver is a standard MSA multi-mode transceiver for 40 Gigabit Ethernet. 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. Mellanox 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 Mellanox MC2210411-SR4 compatible 40GBASE-SR4 QSFP+ transceiver.

Mellanox MC2210511-LR4 40GBASE-LR4 QSFP+ transceiver is a standard MSA single-mode transceiver for 40 Gigabit Ethernet. It 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. The image below shows a Mellanox MC2210511-LR4 compatible 40GBASE-LR4 QSFP+ transceiver.

Mellanox QSFP+ transceivers provide outstanding performance for high-bandwidth applications, including 40 Gigabit Ethernet, QDR, FDR Infiniband, and other communications standards. In addition to meeting or exceeding InfiniBand Trade Association (IBTA) and IEEE standards, Mellanox certified modules are 100% tested on Mellanox equipment to ensure optimal signal integrity and the best end-to-end performance.

Nowadays, QSFP+ transceivers have been widely used by people as it can provide higher bandwidth. And other kinds of 40G products, such as direct attach copper cables and active optical cables, also become popular devices in 40 Gigabit Ethernet applications.
