How many types of multi-source protocols does the optical module have?

How big is the optical module depends upon the proper execution factor, which is usually specified by various multi-source agreement (MSA) organizations. There are various types of interfaces for early equipment. Each equipment manufacturer's tools can only just use its specific optical module, which can't be used in the industry. Therefore, some industry leaders have built an organization to discuss the utilization of the same interface and the same size of optical modules between equipment suppliers. This group is definitely MSA.

The MSAs define the size of the optical module are mainly SFP MSA, XFP MSA, CXP MSA, QSFP MSA, CFP MSA, OSFP MSA, and QSFP-DD MSA, which are also the primary package types that stick to the market.

Listed below are various kinds packaged MSAs for transceiver modules:

GBIC transceiver modules, an abbreviation of Giga Bitrate Interface Converter, was very popular in the 1990s. It converts gigabit electrical signals into optical signals and can be used for hot swapping. GBIC can be an interchangeable product that meets international standards. Prior to the SFP package appeared, this optical module was trusted in network products such as for example switches and routers, and was gradually replaced by SFP optical modules. Weighed against the 1X9 packaged module, the GBIC module has apparent advantages. Because of its hot-swappable characteristics, the GBIC product as an unbiased module allows users to easily update and keep maintaining the optical module and locate the fault. However, with the continuous development of the network, the shortcomings of GBIC modules have steadily emerged. The primary disadvantage can be that the size is certainly too big, producing a low density of optical ports on the service board, which cannot accommodate a sufficient number of GBICs on the board and cannot adjust to the rapid development of the network.

SFP transceiver modules (Small Form-factor Pluggables) that is, small hot-swap optical module, is an upgraded version of the first GBIC module, inherits the hot-plug feature of GBIC, using LC head, weighed against GBIC fiber module, it The volume is smaller and the integration is higher, which greatly escalates the port density of network equipment and adapts to the rapid development trend of the network. Therefore, it has the widest application and happens to be the most popular optical module on the market. Said optical module is this kind. SFP optical modules also draw on the benefits of SFF miniaturization. At the moment, the major devices manufacturers, without exception, GBIC products abandoned, only use SFP optical module products. Because of the adoption of unified standards, SFP products of varied manufacturers are compatible, and SFP products can be bought as another network device.

XFP transceiver modules, (10 Gb small form factor pluggable module) is a hot-swappable optical transceiver in addition to the communication process. XFP is often found in 10G bps SONET/SDH Fibre Channel 10 Gigabit Ethernet and other applications, including CWDM and DWDM links. It offers a module that's not the same as the Xenpak architecture and its own 4-channel interface. XFP is normally a full-speed single-channel serial module linked by an XFI (10 Gb serial interface), that may replace Xenpak and its derivatives.

SFP+ transceiver modules , also known as SFP PLUS optical module, can be an upgrade of SFP optical module, with an increased transmission rate, usually up to 8.5G or 10G (10 Gigabit), this module is more heavy compared to the XFP module that appeared previous Small, it transfers the circuit used for clock and data recovery from the chip to the line card, and compresses the size and power consumption by putting the CDR and electrical dispersion compensation beyond your module. At the same time, it gets the same rate, so that it can be done for communication apparatus manufacturers to deploy more dense optical modules in the same space, therefore the application is now a growing number of widely.

QSFP/QSFP+ transceiver modules (Quad Small Form-factor Pluggable (PLUS)): QSFP was created to meet the marketplace demand for higher-density high-speed pluggable solutions. It includes a four-channel pluggable SFP interface. The interface transmission rate reached 40Gbps. Many mature key technologies in XFP have already been put on this design. QSFP can be utilized as an optical fiber solution, and its own speed and density are much better than the 4-channel CX4 interface. Since it can support four channels of data transmission at 10Gbps per channel at the same port level of XFP, the density of QSFP can reach 4 times that of XFP products and three times that of SFP+ products. This interface offers been adopted by the InfiniBand standard.

CFP transceiver modules , short for form-factor pluggable, was initially proposed in '09 2009. It really is an optical device that transmits high-rate data signals. It could usually transmit 40G or 100G ultra-high speeds, in fact it is also among the top high-speed modules at the moment. Because there are fewer manufacturers, the purchase price is higher. The rate of every electrical interface of CFP is thought as 10Gb/s level, and the module rates of 40G and 100G are realized through 4x10Gb/s and 10x10Gb/s electrical interfaces.

With the development of technology, how big is optical modules can be smaller and smaller, and the info capacity transmitted per unit time may also become larger and larger. There will be new MSAs in the potential.
