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).
BX (officially BX10)–1490nm/1310nm, Single Fiber Bi-Directional Gigabit SFP Transceivers, paired as BX-U and BX-D for uplink and downlink respectively, also for distances up to 10km. [21] [22] Variations of bidirectional SFPs are also manufactured which use 1550nm in one direction, and higher transmit power versions with link length capabilities up to 80km. To distinguish SMF from MMF cables, SMF cables are usually yellow, while MMF cables are orange (OM1 & OM2) or aqua (OM3 & OM4). However, in fiber optics there is no uniform color for any specific optical speed or technology with the exception being angular physical connector (APC), it being an agreed color of green.

The GLC-BX-D-I and GLC-BX-U-I are the Industrial temperature rated (IND) counterparts of GLC-BX-D and GLC-BX-U SFPS. This allows link operation in harsh environmental conditions where the module case temperature can be in the range -40°C to 85°C. Hot-swappable input/output device that plugs into an Ethernet SFP+ port of a Cisco switch (no need to power down if installing or replacing)
A slightly larger sibling is the four-lane Quad Small Form-factor Pluggable ( QSFP). The additional lanes allow for speeds 4 times their corresponding SFP. In 2014, the QSFP28 variant was published allowing speeds up to 100Gbit/s. [6] In 2019, the closely related QSFP56 was standardized [7] doubling the top speeds to 200Gbit/s with products already selling from major vendors. [8] There are inexpensive adapters allowing SFP transceivers to be placed in a QSFP port. The Cisco 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade Multimode Fiber (MMF). To make sure 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. For additional information on mode conditioning patch cord requirements please see: https://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html. There is a lower cost, lower power variant sometimes referred to as 10GBASE-SRL (10GBASE-SR lite). This is inter-operable with 10GBASE-SR but only has a reach of 100 meters. [31] 10GBASE-LR [ edit ] 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.

Variations of bidirectional SFPs are also manufactured which higher transmit power versions with link length capabilities up to 40km. The adoption of 10GbE has been more gradual than previous revisions of Ethernet: in 2007, one million 10GbE ports were shipped, in 2009 two million ports were shipped, and in 2010 over three million ports were shipped, [5] [6] with an estimated nine million ports in 2011. [7] As of 2012 [update], although the price per gigabit of bandwidth for 10GbE was about one-third compared to Gigabit Ethernet, the price per port of 10GbE still hindered more widespread adoption.

The Cisco 10GBASE-ER Module supports a link length of up to 40 kilometers on standard Single-Mode Fiber (SMF, G.652). 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. Dove, Dan (24 May 2004). "10GBase-CX4 lowers 10G Ethernet cost". Network World . Retrieved 19 December 2014. 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.When shorter distances of Single-Mode Fiber (SMF) are used, it might be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the SFP at each end of the link whenever the fiber-optic cable span loss is less than 8 dB. The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard Single-Mode Fiber (SMF,G.652). The power consumptions of 10Gb switches also vary in different vendors. This is a vital factor needed to be considered for every switch manager, especially in data centers, as the switch and port numbers are both very large. Some 10G switches are configured with independent overload and short circuit protection, and others have LED indicators to show power status.
