The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard Single-Mode Fiber (SMF,G.652). T uses the IEC 60603-7 8P8C modular connectors already widely used with Ethernet. Transmission characteristics are now specified to 500 MHz. To reach this frequency Category 6A or better balanced twisted pair cables specified in ISO/IEC 11801 amendment 2 or ANSI/TIA-568-C.2 are needed to carry 10GBASE-T up to distances of 100m. Category 6 cables can carry 10GBASE-T for shorter distances when qualified according to the guidelines in ISO TR 24750 or TIA-155-A.
The Cisco SFP-10G-ZR-I is a multirate 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e module for industrial operating temperature range. The SFP-10G-ZR-I has a limiting electrical interface receiver, which does not require EDC PHY on the host board, it can be plugged into any SFP+ port. It supports link lengths of up to 70 kilometers on standard Single-Mode Fiber (SMF, G.652), assuming a fiber chromatic dispersion of 20ps/(nm *km). This interface is not specified as part of the 10 Gigabit Ethernet standard and is instead built according to Cisco specifications. The SFP-10G-ZR-I has a cold start at -40⁰C; the transceiver will be operational except optical traffic is not supported from -40⁰ to -28⁰C, all other low speed features (DOM, I2C, etc.) are operational. The module is fully operational from -28⁰C to 85⁰C. The Cisco GLC-BX40-D-I, GLC-BX40-DA-I, and GLC-BX40-U-I SFPs operate on a single strand of standard SMF.LX–1310nm, for distances up to 10km (originally, LX just covered 5km and LX10 for 10km followed later) LRM allows distances up to 220 metres (720ft) on FDDI-grade multi-mode fiber and the same 220m maximum reach on OM1, OM2 and OM3 fiber types. [24] 10GBASE-LRM reach is not quite as far as the older 10GBASE-LX4 standard. Some 10GBASE-LRM transceivers also allow distances up to 300 metres (980ft) on standard single-mode fiber (SMF, G.652), however this is not part of the IEEE or MSA specification. [34] To ensure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4. [35] 10GBASE-ER [ edit ] SX+/MX/LSX (name dependent on manufacturer)–1310nm, for a distance up to 2km. [20] Not compatible with SX or 100BASE-FX. Based on LX but engineered to work with a multi-mode fiber using a standard multi-mode patch cable rather than a mode-conditioning cable commonly used to adapt LX to multi-mode.

From Core to Edge to Unique Forum Factor
Although it is not mentioned in any official specification document the maximum data rate of the original SFP standard is 5Gbit/s. [27] This was eventually used by both 4GFC Fibre Channel and the DDR Infiniband especially in its four-lane QSFP form.

The Cisco 1-Gbps SFPs are supported across a variety of Cisco networking equipment *. For more details, refer to the document SFP Compatibility Matrix at: https://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6981.pdf Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10GbE defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations of Ethernet standards [1] so half-duplex operation and repeater hubs do not exist in 10GbE. [2] The first standard for faster 100 Gigabit Ethernet links was approved in 2010. [3]Gbit/s The original QSFP document specified four channels carrying Gigabit Ethernet, 4GFC ( FiberChannel), or DDR InfiniBand. [49] 40 Gbit/s (QSFP+) QSFP+ is an evolution of QSFP to support four 10Gbit/s channels carrying 10 Gigabit Ethernet, 10GFC FiberChannel, or QDR InfiniBand. [50] The 4 channels can also be combined into a single 40 Gigabit Ethernet link. 50 Gbit/s (QSFP14) The QSFP14 standard is designed to carry FDR InfiniBand, SAS-3 [51] or 16G Fibre Channel. 100 Gbit/s (QSFP28) The QSFP28 standard [6] is designed to carry 100 Gigabit Ethernet, EDR InfiniBand, or 32G Fibre Channel. Sometimes this transceiver type is also referred to as QSFP100 or 100G QSFP [52] for sake of simplicity. 200 Gbit/s (QSFP56) QSFP56 is designed to carry 200 Gigabit Ethernet, HDR InfiniBand, or 64G Fibre Channel. The biggest enhancement is that QSFP56 uses four-level pulse-amplitude modulation ( PAM-4) instead of non-return-to-zero (NRZ). It uses the same physical specifications as QSFP28 (SFF-8665), with electrical specifications from SFF-8024 [53] and revision 2.10a of SFF-8636. [7] Sometimes this transceiver type is referred to as 200G QSFP [54] for sake of simplicity. The Cisco SFP-10G-LR-X is a multirate 10GBASE-LR, 10GBASE-LW, and OTU2/OTU2e module for extended operating temperature range. It supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652).

Retrieved 6 August 2023. 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. Multiple vendors introduced single strand, bi-directional 10Gbit/s optics capable of a single-mode fiber connection functionally equivalent to 10GBASE-LR or -ER, but using a single strand of fiber optic cable. Analogous to 1000BASE-BX10, this is accomplished using a passive prism inside each optical transceiver and a matched pair of transceivers using two different wavelengths such as 1270 and 1330nm. Modules are available in varying transmit powers and reach distances ranging from 10 to 80km.

Support Virtual Router Redundancy Protocol (VRRP) Support Virtual Router Redundancy Protocol (VRRP) Support Virtual Router Redundancy Protocol (VRRP) Over the years the Institute of Electrical and Electronics Engineers (IEEE) 802.3 working group has published several standards relating to 10GbE. The power consumption of 10GBASE-T switch is 1.5 to 4 watts per port depending on the distances, while 10GbE SFP switch uses approximately 0.7 watts per port regardless of distances. Moreover, 10G SFP+ switch offers lower latency with about 0.3 microseconds per link. 10GBASE-T switch latency is about 2.6 microseconds per link due to more complex encoding systems within the equipment. With the advantages of low power consumption and latency, 10Gb SFP+ switch is suitable for large high-speed applications.
