SFP+ MSA: Key Information You Should Be Aware Of

In data communication, the seamless transfer of high-bandwidth data between network devices is paramount. At the heart of this efficiency lies the Small Form-Factor Pluggable Plus Multi-Source Agreement (SFP+ MSA), a standardized framework shaping the design and functionality of optical transceivers. Explore with us the transformative role of SFP+ MSA, a driving force in standardizing interoperability for optical transceivers beyond mere specification.

Navigating the Impact of SFP+ MSA in Optical Transceivers

Definition and Expansion of MSA

MSA, an abbreviation for Multi-Source Agreement, is a protocol that enables different manufacturers to produce optical module products with similar basic functionalities and interoperability. The interface types of optical modules from various manufacturers were once diverse. To address the lack of interoperability, multiple manufacturers joined forces to create an organization dedicated to standardizing specifications for the interface types, installation, and functionalities of optical modules. MSA emerged as a supplement to IEEE standards. For optical modules, the MSA standard not only defines their physical dimensions but also outlines their electrical and optical interfaces, creating a comprehensive standard for optical modules.

Significance of SFP+ MSA in Networking Standards

Due to the MSA standard defining the physical dimensions and interface types of optical modules, suppliers strictly adhere to MSA standards during system design to ensure interoperability and interchangeability between optical modules. For end-users, the MSA standard holds crucial significance for two main reasons:

Firstly, the MSA standard offers users a variety of choices. As long as an optical module complies with the MSA standard and demonstrates good compatibility, customers can choose any optical module needed from any third-party supplier.

Secondly, concerning costs, the MSA standard, to some extent, prevents the optical module market from being monopolized by certain major manufacturers. This situation contributes to lowering the network construction costs for end-users.

Classification Guide to Fiber Optical Module

Owing to the rapid progresses made in fiber optical technology, more and more networking infrastructure installations and upgrades choose fiber optic links for high-data-rate transmission. There is no question that compared with copper solutions, fiber optics provides greater bandwidth, more reliable data transmission, and immunity to electromagnetic interference and radio-frequency interference (EMI/RFI), crosstalk, impedance problems, and more. For constituting such fiber optic links, fiber optic module, one of the fast-growing transmission components, are instrumental, and work well in these applications where high-bandwidth and long-distance transmission are needed.

Along with the fiber optical technology advances, fiber optic module has been constantly designed and reinnovated, so as to better facilitate electrical-optical-electrical signal conversion. They are classified into several categories according to different standards regarding package, transmission mode, data rate and power supply. This text will talk about every classification standard in details.

Based-on Different Package Standard

MSAs (Multi-Source Agreements) are agreements between multiple manufacturers, system integrators, and suppliers, specifying parameters for system components and their guideline values, such as the electrical and optical interfaces, mechanical dimensions and electro-magnetic values. The equipment vendors follow these MSA defined values for designing their systems to ensure interoperability between interface modules. The form-factor or the MSA-type is needed so that the transceiver can mechanically and electrically fit into a given switch, router, etc. Transceiver MSAs define mechanical form factors including electric interface as well as power consumption and cable connector types. There are various MSA types: SFP (eg. E1MG-TX), SFP+, QSFP and so on.

By Transmission Mode Standard

When talking about this standard, single mode optical modules and multi-mode optical modules come to the central point.

  • Single Mode Fiber Optic Module

Single-mode optical modules, or single-mode transceivers, just as their name show, are designed to work over single mode fibers (SMFs). Compared with multimode fiber (MMF), SMF fiber core is smaller and the wavelength of the laser is narrower, meaning that while transmitting optical signals, SMF is able to deliver higher bandwidth at the much longer distances, like 2km, 10km, 40km, 60km, 80km and 120km transmission. Commonly-seen single-mode transceiver types include 10GBASE-LR, 1000BASE-LR, 1000BASE-BX, etc..

  • Multimode Fiber Optic Module

Multimode optical modules, or multimode transceivers, operate over MMF which uses a much bigger core and usually uses a longer wavelength of light. Thus, the optics used in MMF has a higher capability to gather light from the laser, for short distance transmission, with distance reach ranging from 100m to 500m. 10GBASE-SR is one of the most widely-used multi-mode transceiver types, such as AFBR-703SDZ-IN2. This Avago Intel compatible 10GBASE-SR SFP+ transceiver listed in FS.COM works over MMF with 850nm laser light for 300m distance reach.

According to Data Rate & Power Supply Standard
  • The connection between two network devices is realized with the help of protocols. It is imperative to know which protocol and data rate the switch or router supports. There are various protocols such as Ethernet, Fiber Channel (FC), InfiniBand, SONET/SDH, CPRI and so on. Each of these protocols supports their own data rates. For example Gigabit Ethernet (GbE) can range from 1Gb/s to 100Gb/s, while FC ranges from 1GFC (1.0625Gb/s) to 16GFC (14.025Gb/s).
  • As for power supply, there are built-in switching power transceiver and eternal power supply transceiver. The built-in switching power transceiver is designed for the carrier grade power. It supports equipment power protection, filters, and a wide power supply voltage regulator, reducing the external point of failure arising from the mechanical contact. By contrast,the external power supply transceiver is made for multi-use civilian equipment, and it is compact and cheap.
  • Of course, the classification standards of fiber optic module is not limited to those three points mentioned above. Other standards are also workable, such as the network management standard. It’s known that there are managed optical modules and unmanaged optical modules. The former type allows additional network monitoring with fault detection, free from configuration function. By contrast, the latter, without monitoring function, allows automatic communication of the devices that are connected to unmanaged optical modules.
Conclusion

When your networking projects call for fiber optic module for fiber optic links, these classification standards will work, since they help you to choose the right fiber optic modules for applications to ensure the reliable data transmission. FS.COM offers an ocean of fiber optic modules which are fully compatible with major brands, including the Brocade E1MGTX, and Avago Intel AFBR-703SDZ-IN2 mentioned above.
