Front-Panel Description
Catalyst 1900 Series Installation and Configuration Guide
1-6
The model with two fiber-optic ports (A and B) use MT-RJ connectors and have a
fiber-optic wavelength of 1300 nanometers. To connect each fiber-optic port on the switch
to an SC or ST port on a 100BaseFX-compatible device on your network, you must use the
appropriate MT-RJ fiber-optic patch cable. 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)
For connection information, see the “Connecting to the Switched 100-Mbps Fiber-Optic
Ports” section on page 2-29.
