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.
The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF,G.652). The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. The GLC-BX80-D-I and GLC-BX80-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.

From Core to Edge to Unique Forum Factor
PR has three power budgets specified as 10GBASE-PR10, 10GBASE-PR20 and 10GBASE-PR30. [24] :75.1.4 10GBASE-BR [ edit ] 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. The dual-rate 100M/1G 10Km SFP is interoperable with the IEEE 100BASE-LX and 1000BASE-LX/LH standards. Datasheet" (PDF). Arista Networks. The Arista 7100T switches support 10GBASE-T over Category 6a cabling up to 100m, but also support Category 5e (Performance of 10GBASE-T over Cat-5e cabling is not specified in the standard and thus cannot be guaranteed. Field testing is recommended before deployment to establish the feasibility of using existing Cat-5e cabling.) and Category 6 cabling with distances up to 55m. The SFP-10G-BX40D-I and SFP-10G-BX40U-I SFPs 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.
LX–1310nm, for distances up to 10km (originally, LX just covered 5km and LX10 for 10km followed later) 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. [37] [38] SFP+ also introduces direct attach for connecting two SFP+ ports without dedicated transceivers. Direct attach cables (DAC) exist in passive (up to 7m), active (up to 15m), and active optical (AOC, up to 100m) variants. s Bidirectional 10km Gen2 SFP+ Optical Transceiver".
