Cisco 10GBASE-LR SFP Module for 10-Gigabit Ethernet Deployments, Hot Swappable, 5-Year Standard Warranty (SFP-10G-LR=)

Product Information

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-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 10GBASE-LR Module supports a link length of 10 kilometers on standard Single-Mode Fiber (SMF, G.652). Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

The Cisco SFP-10G-SR is in full compliance with the 10G BASE-SR standard. This module has a link length of 26m on the most commonly used standard FDDI- grade multimode fiber. FDDI stands for Fiber Distributed Data Interface. It supports a link length of 300m over OM3 cables and a link length of 400m over OM4 cables. 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. Whenever you see -X, that means it has extended ability to operate under wider temperature variation, from-40°C to 85°C(-40°Fto 365°F). There is no other significant difference from the standard versions, and no reason to use -X equipment unless you're operating in extreme temperatures.

Multi-mode cable is more complex. It utilizes multiple beams, which bounce diagonally throughout a somewhat larger (62.5 micron) core. The beams are then collected at the receiving end and recombined. This allows multi-mode to achieve high speeds at a lower power use -and usually slightly lower cost- but the nature of the format means that interference and signal degrading become an issue in longer cables. So multi-mode is generally used for Short Reach (SR) applications. The SFP-10G-ZR-I has a cold start at -40 ⁰ C, the transceiver will be operational except optical traffic is not supported from -40 ⁰ C to -28 ⁰ C, all other low speed features (DOM, I2C, etc.) are operational. The module is fully operational -28 ⁰ C to 85 ⁰ C. 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 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. Dette advarselssymbolet betyr fare. Du er i en situasjon som kan føre til skade på person.

Cisco multirate 10GBASE-LR/10GBASE-LW/OTU2e SFP+ transceiver module for SMF, 1310-nm wavelength, extended temperature range The Cisco 10GBASE-ZR module supports link lengths of up to about 80 kilometers on standard SMF (G.652). This interface is not specified as part of the 10 Gigabit Ethernet standards and is, instead, built according to Cisco specifications. SFP-10G-ZR-S does not support FCoE. set baseFontWeight = "normal" %} /* More than likely, you will use one of these values (higher = bolder): 300, 400, 700, 900 */ LRM transceivers are often mistaken for 10GBASE-LR SFP+ optics, but it is not the same. 10GBASE-LRM SFP+ makes use of the 1310nm lasers, however, it has a maximum reach of only 220 m over standard multimode fibers such as OM3/OM4. This transceiver is available in the XFP and SFP+ form factors.
