SFP Transceiver Specifications

---

This appendix provides cabling specifications for the SFP transceivers supported on the Cisco ME 6500 Ethernet switch. Figure B-1 shows an optical SFP transceiver with the major features labeled. Figure B-2 shows an SFP transceiver that uses Category 5, 5e, 6, or 6a copper network interface cable.

---

Note Each port must match the wavelength specifications on the other end of the cable. For reliable communications, the cable must not exceed the required cable length.

1 A mode-conditioning patch cord, as specified by the IEEE standard, is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP transceivers, and a short link distance can cause transceiver saturation, resulting in an elevated bit error rate (BER). When using the LX/LH SFP transceiver with 62.5-micron diameter MMF, you must also install a mode-conditioning patch cord between the SFP transceiver and the MMF cable on both the sending and receiving ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 feet (300 m). 2 ITU-T G.652 SMF as specified by the IEEE 802.3z standard. 3 Single-strand SMF. 4 CWDM SFP transceivers are supported on uplink ports only. 5 DWDM SFP transceivers are supported on uplink ports only.

Note The maximum Rx indicates the overload threshold of the receiver. The minimum Rx indicates the lowest acceptable signal level coming into the receiver that allows correct signal recognition.

Table B-4 list the physical and environmental specifications for the SFP transceivers.

Item	Specification
Dimensions (H x W x D)	0.04 x 0.53 x 2.22 in. (8.5 x 13.4 x 56.5 mm)
Operating temperature Storage temperature	32° to 122°F (0° to 50°C) -40° to 185°F (-40° to 85°C)

Note You can use any combination of SFP modules that your Cisco device supports. The only restrictions are that each SFP port must match the wavelength specifications on the other end of the cable and that the cable must not exceed the stipulated cable length for reliable communications.

---

The Coarse Wavelength Division Multiplexing (CWDM) SFPs are hot-swappable, transceiver components that you plug into SFP-compatible uplink ports. The CWDM SFP transceiver uses an LC optical connector to connect to single-mode fiber-optic (SMF) cable. You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) modules or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables. Table B-5 lists the color code and the laser operating wavelength for each of the CWDM SFP transceivers.

---

Note CWDM SFP transceivers are supported on the chassis uplink ports only.

DWDM SFP transceivers are used as part of a DWDM optical network to provide high-capacity bandwidth across an optical fiber network. There are 32 fixed-wavelength DWDM SFPs that support the International Telecommunications Union (ITU) 100-GHz wavelength grid. The DWDM SFP transceivers have a duplex SC connector.

---

Note DWDM SFP transceivers are supported on the chassis uplink ports only.

---

Note Only connections using patch cords with PC or UPC connectors are supported. Patch cords using APC connectors are not supported.
