An SFP port is a slot on a network device or computer into which small form-factor pluggable (SFP) transceivers are inserted. An SFP port connection enables the transfer of data between two devices via an SFP transceiver and appropriate cabling. In other words, the port and its corresponding SFP transceiver allow the two devices to communicate with each other over an extended distance. a b QSFP-DD MSA (July 26, 2022).

C ompatibility . SFP+ is used in 10-Gigabit Ethernet applications while SFP is for 100BASE or 1000BASE applications.SFP complies with standards of IEEE802.3 and SFF-8472 while SFP+ is based on SFF-8431. The Cisco 10GBASE-SR module supports a link length of 26 meters on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000 MHz *km MMF (OM3), up to 300-meter link lengths are possible. Using 4700 MHz *km MMF (OM4), up to 400 meter link lengths are possible. SFP-10G-SR-S does not support FCoE. A GLC-BX80-D-I device is always connected to a GLC-BX80-U-I device with a single strand of standard SMF with an operating transmission range up to 80 km. The SFP+ transceivers (10 gigabits enhanced small form-factor pluggable) are interchangeable compact fiber connectors. CWDM SFP+ transceivers provide the right tools for a single network device to connect to various types of fiber optic cables and distances. DWDM transceivers support wavelengths between 1525–1565 nm (C band) with 100GHz spacing. CWDM SFP vs. CWDM SFP+ Compatibility While SFP+ is mainly linked to 10G, SFP28 is commonly associated with 25G connections. This is due to the fact that SFP28 can reach up to a transmission rate of 28Gbps, which gives it its name: SFP28. In turn, SFP28 has much greater bandwidth capabilities.
Conclusion
The GLC-GE-DR-LX SFP can interoperate with other 1G SFPs/interfaces as long as those are based on 1000BASE-LX/LH standard. No attenuator is needed in any fiber strand.
Cisco quality Identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco SFP, SFP+ or QSFP are all types of transceivers used to connect a switch or other network device to copper or fibre cable. They are most commonly used to add fiber ports. Which SFP transceiver you choose depends on the cable type, application, required optical range for the network and the desired data transmission rate. What is an SFP?SFP stands for Small Form-factor Pluggable. It is a hot-pluggable transceiver that plugs into the SFP port of a network switch and supports SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP specifications are based on IEEE802.3 and SFF-8472. They are capable of supporting speeds up to 4.25 Gbps. Due to its smaller size, SFP replaces the formerly common gigabit interface converter ( GBIC). Therefore SFP is also called Mini-GBIC. By choosing different SFP module, the same electrical port on the switch can connect to different fiber types (multimode or single-mode) and different wavelengths.
SFP can also called “Small Form-factor Pluggable”. It is a hot-pluggable transceiver that plugs into the SFP port of a network switch and supports SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP specifications are based on IEEE802.3 and SFF-8472. They are capable of supporting speeds up to 4.25 Gbps. The compact small form-factor pluggable ( cSFP) is a version of SFP with the same mechanical form factor allowing two independent bidirectional channels per port. It is used primarily to increase port density and decrease fiber usage per port. [44] [45] SFP-DD [ edit ] INF-8077i: 10 Gigabit Small Form Factor Pluggable Module" (PDF).

Retrieved September 25, 2023. wire serial interface data line (using the CMOS EEPROM protocol defined for the ATMEL AT24C01A/02/04 family [65]) Small Form-factor Pluggable ( SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper cable. [1] The advantage of using SFPs compared to fixed interfaces (e.g. modular connectors in Ethernet switches) is that individual ports can be equipped with different types of transceivers as required. Quad Small Form-factor Pluggable ( QSFP) transceivers are available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required optical reach over multi-mode or single-mode fiber. The Cisco SFP-10G-SR-I is a multirate 10GBASE-SR, 10GBASE-SW and OTU2/2e module for industrial operating temperature range. This module also supports CPRI datarate options 3, 4, 5, 6, 7, 7a, 8. It supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade Multimode Fiber (MMF). Using 2000MHz *km MMF(OM3), up to 300m link lengths are possible. Using 4700MHz *km MMF (OM4), up to 400m link lengths are possible.
Mechanical dimensions [ edit ] Side view of SFP module. Depth, the longest dimension, is 56.5mm (2.22in). The Cisco 10GBASE-ER Industrial Temperature Module supports a link length of up to 40 kilometers on standard Single-Mode Fiber (SMF, G.652). The SFP-10G-ER-I for Industrial Operating Temperature Range is a multirate 10GBASE-ER, 10GBASE-EW and OTU2/2e module. Single Fiber Bidirectional SFP Transceiver (PDF), MRV, archived from the original (PDF) on April 19, 2016 Small form-factor pluggable specifications are published in the SFP Multi-Source Agreement, which enables you to mix and match components from different vendors. However, some IT equipment manufacturers sell network devices that support only vendor-specific SFPs. To ensure compatibility, review the vendor’s optics testing centeror ask your vendor to verify compatibility.The CWDM SFP and SFP+ transceiver modules are compatible with almost all network switches/routers, media converters and PoE switches. A GLC-BX40-D-I or GLC-BX40-DA-I device connects to a GLC-BX40-U-I device with a single strand of standard SMF with an operating transmission range up to 40 km. Multi-Mode Fiber (MMF): as MMF has a much wider core (typically 50μm or 62.5μm), it allows multiple modes of light to propagate. The common MMFs are used for short distance transmissions (max 100m – 500m) The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. The GLC-BX40-D-I, GLC-BX40-DA-I, and GLC-BX40-U-I SFPs also support Digital Optical Monitoring (DOM) functions according to the industry-standard SFF-8472 Multisource Agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
