The term „MSA“ refers to the multi-source agreement, an agreement between several manufacturers of standardized products that will be compatible for a number of telecommunications operators. These agreements serve as a „de facto“ standard and have created a competitive market for MSA-compliant optical trans-receivers, certain cables and other network devices. Some important multi-source agreements for optical transceurs are presented in the table below: MSAs indicate component parameters and their indicative values, such as mechanical dimensions, electrical and optical interfaces and electromagnetic values. Device manufacturers are attacking MMAs to develop their systems. This ensures interoperability and interchangeability between interface modules. Products that comply with multi-source agreements include: optical transceurs such as SFP, SFP, XENPAK, QSFP, XFP, CFP, etc.; fibre optic cables and other network devices. If you refer to plug-in transceivers, you will often see that manufacturers indicate that they are „MSA-compatible,“ but what does that mean? MSA is synonymous with a multi-source agreement, an agreement between several manufacturers to manufacture products that are compatible between manufacturers, by being de facto standards and creating a competitive market for interoperable products. Products for msAs include optical transceivers, fibre optics and other network devices. A multi-source agreement, commonly known as MSA, is an agreement between several manufacturers to manufacture products with the same basic functionality and ease of use between different suppliers. Member States act as de facto standards and create and promote a competitive market for interoperable products instead of a monopoly structure. TXO is capable of testing complete modules and systems that belong to a variety of multi-supplier platforms. MSAs, like most standard efforts, are particularly important because they can offer customers a choice between the suppliers from which they purchase products.
Freedom of choice is the basis for efficient market functioning. Customers in the market should benefit from several independent suppliers, each competing for market share. This behaviour requires suppliers to be as efficient and creative as possible, reduce costs and offer customers the widest range of options.
