SFP Transceiver Module [Fiber-Optic LC Connector] 1000BASE-T SFP Transceiver Module [RJ-45 Connector] Cisco Part Gigabit Description Number Ethernet SFP GLC-SX- Operates on 50 μm multimode Cisco fiber links up to 550 m and on 1000BASE-SX SFP-GE- 62.5 μm FDDI-grade multimode fibers up to 220 m.
A Cisco Coarse Wavelength Divison Multiplexing (CWDM) SFP is a hot-swappable input/output device that plugs into an SFP port or slot of a Cisco switch or router, and links the port with the fiber-optic network. The Cisco CWDM SFPs are multirate parts that support both Gigabit Ethernet and Fibre Channel (1 Gigabit and 2 Gigabit).
Gb Fibre Channel Supported Catalyst Switches This section lists the Cisco Catalyst Switches that support the Cisco SFP Transceiver Modules. Note: If a module / device supports both 100M SFP and Gigabit Ethernet SFP transceiver modules, they can be used at the same time on appropriate ports. However, aggregating (channelling) different types of transceiver modules is not supported.
Safety Guidelines Laser Safety Before you install SFP modules in a Cisco device or attempt to operate or service a Cisco device equipped with SFP modules, you must read and observe the important safety information in this publication. Refer to...
Note: See the Safety Guidelines section before you install the SFP Transceiver Modules. Types of SFP Transceiver Latches SFP Transceiver Modules can have three types of latching devices to secure an SFP transceiver in a port socket. Determine which type of latch your SFP transceiver uses before you complete the installation and removal procedures: SFP transceiver with a Mylar tab latch.

Ensure that you are installing the SFP transceiver in the correct orientation for your Cisco device. Refer to the hardware installation instructions that came with your Cisco device for more details.
The LED turns green when the SFP transceiver and the target device have an established link. The LED turns amber while STP discovers the network topology and searches for loops. This process takes about 30 seconds, and then the LED turns green. If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a problem with the adapter installed in the target device.
4. Place the removed SFP transceiver in an antistatic bag or other protective environment. Cabling Specfications This table shows cabling specifications for the Cisco SFP transceivers installed on a FastEthernet / Gigabit Ethernet SFP port. Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (MMF and SMF [G.652] is 2 meters [6.5 feet]).
Use Third Party SFP Modules The use of third party SFP transceivers with Cisco devices is not supported by Cisco. Cisco-approved SFP modules have a serial EEPROM that contains the module serial number, the vendor name and ID, a unique security code, and cyclic redundancy check (CRC).
200k. This problem is resolved in Cisco IOS Software Releases 12.2(18)SXE4, 12.2(18)SXF and later. In order to resolve this problem, upgrade the Cisco IOS Software on the switch to the latest maintenance release, which can be downloaded from the Software Download (registered customers only) page.

The Links Do Not Come Up in Cisco 3800 Series Routers with SPFs for Connecting to Cisco Catalyst Switches When the SFPs are used to connect a Cisco 3800 Series router to a Cisco Catalyst switch, the link cannot come up, and the show interface command shows down/down.
