40G QSFP+

In the 40G network transmission application, the QSFP+ 40G optical module occupies a position that cannot be ignored. According to different needs, it is applied in different transmission scenarios.

Primus IT supplies a variety of cost-effective and practical 40G QSFP+ optical modules. It can also provide reliable system solutions to help users build data centre access networks more conveniently and flexibly.

Specifications of 40G QSFP+

Introduction of QSFP28 40g

100g SR4 optical module with CDR,4 channel 850nm VCSEL laser array and PIN photodetector array, complies with QSFP28 MSA and IEEE 802.3bm 100GBASE-SR4 Ethernet standards, is compatible with IEEE 802.3ba 40GBASE-SR4 Ethernet and InfiniBand FDR/EDR standards, and can transmit up to 70m/100m over OM3/OM4 multimode fiber.

Parallel optical modules need to be used with MPO optical fiber adapters. 40G/100G SR4 is usually used with 12-core multimode MPO fiber jumpers. The applications of parallel optical modules and MPO technology are constantly developing, which can support higher-speed optical transmission. Many wiring and network experts have pointed out that parallel optical modules and MPO technology can be well applied in 40 Ethernet transmission. It provides a good transmission environment for 40ax 100G Ethernet transmission.

40gb QSFP VS. SFP

40gb SFP transceivers also provide copper interfaces, enabling host devices designed primarily for optical fiber communications to communicate over UTP network cables. There are also wavelength division multiplexing (CWDM) and single-fiber "bi-directional" SFP. Commercial SFP transceivers can provide rates up to 4.25G bps. Several packaging forms of 10 Gbps transceivers are XFP, as well as a new variant "SFP+", which is basic to the SFP package.

40gb QSFP can be used as an optical solution with better speed and density than 4-channel CX4 interfaces.

Because it can support four channels of data transmission at the speed of each channel 10Gbps under the same port volume of XFP, the density of QSFP can be 4 times that of XFP products and 3 times that of SFP+ products. QSFP interface with 4 channels and higher density than CX4 has been adopted by InfiniBand standard.

Primus IT Compatible 40g qsfp+ to 10g sfp+ adapter converter module

The Primus IT Compatible QSFP-to-SFP or SFP+ Adapter (QSA) module provides 10 Gigabit Ethernet and 1 Gigabit Ethernet connectivity for platforms limited to four small form-factor pluggable (QSFP) platforms.

It allows low-speed small form-factor pluggable (SFP) or enhanced small form-factor pluggable (SFP+) modules to be used in QSFP ports or at lower speeds on the other side of the network, which can reach a smooth, cost-effective 40 Gigabit Ethernet migration performance. Primus IT's has done rigorous production testing to ensure the best out-of-the-box installation experience, performance and durability.

As one of the most professional optical module manufacturers, Primus IT specializes in the development and manufacture 100 bases to 400G optical transceivers ( GBIC / SFP / SFP+/ SFP28 / QSFP+ / QSFP28 / XFP / XENPAK / X2 / CFP / CFP2 / AOC / DAC etc.) and provides cost-effective transceivers solutions for customers worldwide in data communications, long-distance transmission, wireless networking and more.
