The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652). 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. The dual-rate 100M/1G 10Km SFP is interoperable with the IEEE 100BASE-LX and 1000BASE-LX/LH standards. The Cisco 10GBASE-SR Module 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. 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.

The standard non-S-class Cisco modules like SFP-10G-SR and SFP-10G-LR can support three protocols including Ethernet, OTN (Optical Transport Network) and WAN-PHY (Wide Area Network Physics). However, the S-class modules can only support Ethernet protocol. The Cisco 10GBASE-LR module supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF) (G.652). SFP-10G-LR-S does not support FCoE. So you have bought an expensive Cisco original brand switch. Now you are considering buying compatible optics for the same. But, do you really need to buy Cisco original brand modules? 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. Cisco has introduced that the S-class modules are suggested to be used in enterprise network. In addition, the operating temperature range is smaller, thus, S-class module is recommended for shorter transmission distance applications compared with other standard modules.The Cisco SFP-10G-LR module is capable of working with a link length of 10 km on any basic single-mode fiber. It is completely in compliance with the 10G Base-LR standard and uses 1310nm lasers. The LR module has no minimum distance, which is why it is ideal for short connections carried over a single mode fiber. Receiver Sensitivity specified over 1530-1565nm only, with 3dB degradation permitted from 1260-1530nm 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.

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. The Cisco 10GBASE-SR Module 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. Cisco only published four 10G S-class SFP+ modules and two 40G S-class QSFP+ modules. The following table listed Cisco S-class modules. Cisco S-class modules seem to have no differences from the non-S-class modules. However, if you read the specification of these modules and the suggestions from Cisco, you will find the differences. The communication over a single strand of fiber is achieved by separating the transmission wavelength of the two devices. SFP-10G-BX40D-I transmits a 1330-nm channel and receives a 1270-nm signal. The SFP-10G-BX40U-I transmits at a 1270-nm wavelength and receives a 1330-nm signal. Apart from the Cisco SFP-10G-LRM module there is another type of module for multimode fibers, called as the SFP-10G-LRM2. This module refers to a type of SFP+ transceiver that are fully compatible with the 10GBASE-LRM standard and have a reach of about 2km over a standard multimode fiber.Note: Parameters are specified over temperature and at end of life unless otherwise noted. When shorter distances of single-mode fiber are used (<40km), an inline optical attenuator must be used to avoid overloading and damaging the receiver. 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) All other products will be delivered via the fastest available method (excluding bank holidays and weekends) and generally within 3-5 days, depending on customer location.

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. The Cisco SFP-10G-SR series has 2 other important modules: the Cisco SFP-10G-SR-X Module and the Cisco SFP-10G-SR-S Module. While the Cisco SFP-10G-SR-S module is a part of the Cisco S-class optics it matches the Cisco SFP-10G-SR module in performance. 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. Cisco quality Identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco Cisco SFP-10G-SR transceivers are input/output devices that are hot-swappable. They are linked with a fiber optic network via a 10 Gigabit Ethernet port. Since these transceivers are MSA compliant and hot-swappable they can be plugged into any Cisco SFP+ based transceiver port directly. You won’t need to power them from the host network system for this. What this does is to make add-ons, moves, and exchanges fast and efficient.The Cisco 10GBASE-LRM Module also supports link lengths of 300m on standard Single-Mode Fiber (SMF, G.652). Extended warranty (optional): Cisco SFP+ modules can be covered in a Cisco SMARTnet® Service support contract for the Cisco switch or router chassis
