Page 41: Duplex Sc Plug And Duplex Sc Connector
Duplex SC Plug and Duplex SC Connector The duplex SC connector connects stations, hubs, and switches that support the 1000BASE-SX fiber interface. Each fiber link needs a clearly defined, external crossover. In other words, the transmit port of one interface must be wired to the receive port of the opposite interface and vice versa. -
Page 42: Appendix C: Cabling Guidelines
APPENDIX C: CABLING GUIDELINES This appendix provides specifications for cables used with the FS726 and FS750 Switches. Fast Ethernet Cable Guidelines Fast Ethernet uses UTP cable, as specified in the IEEE 802.3u standard for 100BASE-TX. The specification requires Category 5 UTP cable consisting of either two-pair or four- pair twisted insulated copper conductors bound in a single plastic sheath. -
Page 43: Category 5 Cable

Page 44: Category 5 Cable Specifications
Computers and workstation adapter cards are usually media-dependent interface ports, called MDI or uplink ports. Most repeaters and switch ports are configured as media-dependent interfaces with built-in crossover ports, called MDI-X or normal ports. Auto Uplink connection, MDI or MDI-X, is needed and makes the right connection. -

Page 46: Figure C-3. Category 5 Utp Cable With Male Rj-45 Plug At Each End
If you are using patch panels, make sure that they meet the 100BASE-TX requirements. NETGEAR recommends Category 5 UTP cable for all patch cables and work area cables to ensure that your UTP patch cable rating meets or exceeds the distribution cable rating. -
Page 47: Cabling
Cabling The 1000BASE-T product is designed to operate over Category 5 cabling. To further enhance the operation, the cabling standards have been amended. The latest standard is Category 5e, which defines a higher level of link performance than is available with Category 5 cable. -
Page 48: Near End Crosstalk (Next
Factors that affect the return loss are: • The number of transition points, as there is a connection via an RJ-45 to another connector, a patch panel, or device at each transition point. • Removing the jacket that surrounds the four pairs of twisted cable. It is highly recommended that, when RJ-45 connections are made, this is minimized to 1-1/4 inch (32 mm). -
Page 49: Fiber Optic Cables
Fiber Optic Cables In North America, use EIA-569-A horizontal 62.5/125 µm multimode optical fiber cable (ANSI/EIA/TIA-492AAAA). Internationally, use ISO/IEC 11801 62.5/125 µm multimode optical fiber cable (IEC 793-2 type A1b, with 1.0db/km attenuation and 500 MHz/km bandwidth). Refer to Table C-2 for the minimum requirements of fiber optic cable. Fiber Cable Specifications Table C-2 lists the electrical requirements of fiber cable. -
