Connecting to the Switched 100-Mbps Fiber-Optic Ports

Warning Class 1 laser product.

Warning Avoid exposure to the laser beam.

Caution Do not remove the rubber plugs from the ﬁber-optic port or the rubber caps from

the ﬁber-optic cable until you are ready to connect the cable. The plugs and caps protect the

ﬁber-optic port and cable from contamination and ambient light.

Note This section provides information and procedures for connecting to the 100-Mbps

ﬁber-optic ports (A and B), which use MT-RJ connectors. For information and procedures

for connecting to the 100BaseFX port that uses a duplex SC connector, see the “Connecting

to the Switched 100BaseFX Port” section on page 2-27.

You can connect the 100-Mbps ﬁber-optic ports (A and B) to 100BaseFX-compatible

network device(s), such as servers, routers, and other switches. These ports use MT-RJ

connectors, and you must use the appropriate MT-RJ ﬁber-optic patch cable to connect

these ports to the SC or ST port(s) on the other 100BaseFX-compatible device(s).

You can order MT-RJ patch cables from your cable vendor, or you can order these cables

from Cisco:

• CAB-MTRJ-SC-MM-1M (1-meter, MT-RJ-to-SC multimode cable)

• CAB-MTRJ-SC-MM-3M (3-meter, MT-RJ-to-SC multimode cable)

• CAB-MTRJ-SC-MM-5M (5-meter, MT-RJ-to-SC multimode cable)

• CAB-MTRJ-ST-MM-1M (1-meter, MT-RJ-to-ST multimode cable)

• CAB-MTRJ-ST-MM-3M (3-meter, MT-RJ-to-ST multimode cable)

• CAB-MTRJ-ST-MM-5M (5-meter, MT-RJ-to-ST multimode cable)

The ﬁber-optic wavelength of the ports is 1300 nanometers.
