Maximum Fiber Optic Cable Distance for 1000BASE-LX

Fiber Size	Fiber Bandwidth		Maximum Cable Length

9/125 micron	N/A		2 m - 10 km (7 - 32808 ft)


Maximum 1000BASE-ZX Fiber Optic Cable Distance

Fiber Diameter		Fiber Bandwidth		Cable Length Range

9/125 micron single-mode		N/A		70* - 100 km (43.5 - 62.1 miles)
fiber (SMF)

*For link spans exceeding 70 km, you may need to use premium single mode fiber or dispersion shifted single mode fiber.

Note: If you need to connect to a device with 62.5/125 micron cable that

has ST-type connectors, SMC provides an optional SC-ST Converter (Part Number: 99-012034-091).

Twisted-Pair Cable and Pin Assignments

Caution: DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs of wires. Each wire pair is identified by two different colors. For example, one wire might be green and the other, green with white stripes. Also, an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation. (See “Cabling Guidelines” on page 4-1for an explanation.)

Figure B-1 illustrates how the pins on the RJ-45 connector are numbered. Be sure to hold the connectors in the same orientation when attaching the wires to the pins.
