Recommended Cables and Cable Specifications
Table 3 lists the IEEE 802.3u cabling specifications. Refer to this table for
cabling recommendations.
Note 1. The Single Mode Fiber Optic Transmitter is rated as a Class 1 Laser.
Note 2. Each Media Converter used inline within a single collision domain will reduce the overall segment length by
40 m (131.24 ft) of fiber.
Note 3. Applies only to the AT-MC104XL, Single Mode Fiber Optic Transmitter/Receiver.
Note 4. Applies only to the AT-MC104LH, Single Mode Fiber Optic Transmitter/Receiver.
