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. 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. Information about Cisco’s environmental sustainability policies and initiatives for our products, solutions, operations, and extended operations or supply chain is provided in the “Environment Sustainability” section of Cisco’s Corporate Social Responsibility (CSR) Report.

The Cisco SFP-10G-ZR is a multirate 10GBASE-ZR, 10GBASE-ZW, and OTU2/OTU2e module. It supports link lengths of up to about 80 kilometers on standard Single-Mode Fiber (SMF, G.652). This interface is not specified as part of the 10 Gigabit Ethernet standard and is instead built according to Cisco specifications.Tämän laitteen saa asentaa, vaihtaa tai huoltaa ainoastaan koulutettu ja laitteen tunteva henkilökunta. Cisco quality Identification (ID) feature enables a Cisco platform to identify whether the module is certified and tested by Cisco LR transceivers are designed for long-range communications, such as wiring buildings together on a large campus or even setting up a Metro Area Network (MAN). They can be either multi-mode or single-mode, and are almost always intended for 100m+ applications. Higher end cables and transceiverscan support transmissions of several kilometers. 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. Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Cisco 1000BASE-EX SFP transceiver module for SMF, 1310-nm wavelength, extended operating temperature range. 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? Basically, these are just extremely long-range fiber variations. ER stands for Extended Reach, and can achieve transmission distances of up to 40km over single-mode fiber.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. 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.
