QSFP + Optical Module Basics
2017-08-15
QSFP + four-channel SFP interface (QSFP), QSFP is designed to meet the market demand for higher-density high-speed pluggable solution was born.
This 4-channel pluggable interface transfer rate of 40Gbps. Many mature technologies in XFP are applied to the design.
Four small volumes of pluggable QSFP + solutions are designed for high density applications. The system components include electromagnetic interference (EMI) shielding, active cable (AOC), QSFP+ passive copper cable assemblies, active copper cable assemblies, optical MTP cable assemblies, optical loopback, host connectors, connectors and cage stacks.
SFF-8436 document specifies a radio transceiver mechanical form factor with latching mechanism, host-board electrical-edge connector and interface. The hot-swappable transceiver integrates 4 transmit and receive channels 4. Molex's QSFP + transceiver can replace 4 standard SFP + transceivers. The result is greater port density and overall system cost savings than traditional SFP + products. The QSFP + cable assemblies are designed to provide stacked connectors that are configured at extremely high density requirements. QSFP+ This system will support 10 G Ethernet, Fiber Channel, InfiniBand *, SAS and SONET / SDH standards using different data rate options. Including InfiniBand * Separate Data Rate (SDR), Dual Data Rate (DDR) and Quad Data Rate (Report), Ethernet System (10 to 40 gbp s), Fiber Channel (8,10 gbp s), SAS (12 gbp S).
QSFP + optical module basics
40G QSFP + optical module in line with SCSI, 40G Ethernet, 20G / 40G Infiniband and other standards, it has four data transmission channels, each channel transmission rate of about 10Gbps, four channels at the same time transmission can achieve 40Gbps transfer rate. QSFP+ This optical module has two main interfaces: LC and MTP / MPO (as shown below), used in single-mode applications and multi-mode applications.
There are several types of QSFP + optical modules, including 40GBASE-SR4, 40GBASE-LR4, 40GBASE-ER4, etc. This section will detail these three optical modules and their applications.
40GBASE-SR4 optical module using MTP / MPO interface, the working wavelength is 850nm, generally used in multi-mode applications. It is used with OM3 / OM4 multimode fiber to transmit distances of 100 m and 150 m, respectively, primarily for connection between network devices in the data center. 40GBASE-SR4 optical module can not only use MTP / MPO fiber jumpers to achieve the connection between two 40G network equipment, and can be used with MTP / MPO LC fiber jumpers to achieve 40G network equipment and 10G network equipment connection.
40GBASE-LR4 and 40GBASE-ER4 optical modules using duplex LC interface, generally used in single-mode applications. These two optical modules have four independent optical signal reception and transmission channels, the need to use WDM technology to multiplex and demultiplex the optical signal, QSFP+ in order to achieve optical signal in the long-distance single-mode fiber transmission. 40GBASE-LR4 optical module transmission distance can reach 10 km, while the 40GBASE-ER4 optical module transmission distance is longer.

012019-10With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

012019-101. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

012019-10AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.
