The Pluggable Small Form-Factor (QSFP) quad transponders are available with a wide range of transmitter and receiver types, allowing users to choose the appropriate transceiver for each connection, to provide the necessary optical range via multimode or monomode fibers. [i] SFF Committee (2001-05-01), INF-8074i Specification for SFP (Small Formfactor Pluggable) Transceiver, called 2012-08-12. The enhanced small form-factor pluggable is an advanced version of the SFP that supports speeds of up to 16 Gbps. The SFP specification was first published on May 9, 2006 and version 4.1 on July 6, 2009. [26] SFP supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network Standard OTU2. It is a popular sector format, supported by many network component suppliers. Although the SFP standard does not mention 16 Gbps Fibre Channel, it can be used at this speed. [27] [a] A SFP-DD,[9] allowing 100 Gbps on two lanes, as well as a QSFP-DD specification[10] for 400 Gbps on 8 lanes of traffic, have been published. These use a form factor that is retrocompatible with their respective predecessors. An alternative alternative solution, the OSFP (Octal Small Format Pluggable) Transceiver is also planned for 400 Gbps of fiber optic connections between network devices over 8 × 50 Gbps of electrical data traces. [11] It is slightly larger than the QSFP form factor, capable of handling higher output performance. The OSFP standard was originally announced on November 15, 2016. [12] Supporters say that a low-cost adapter allows the QSFP module to be compatible.

[13] A small form factor pluggable (SFP) is a kind of transceiver device standardized by the MSA (multi-source agreement). The MSA defines the characteristics of the system and is generally an agreement between several manufacturers. The agreements ensure that any SFP or SFP device from any manufacturer works properly. This article gives you a more complete introduction to the SFP MSA and SFP MSA. Multi-source agreements are not formal standards bodies. Rather, they are agreements made by device manufacturers to develop form factors for communication interfaces. Modern SFP optical transqueurs support standard DDM (Digital Diagnostic Monitoring) functions. [59] This function is also called Digital Optical Surveillance (DOM).
