2-1-3-1. Cabling Requirements for TP Ports⇒ For Fast Ethernet TP network connection⎯ The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of100 meters.⇒ Gigabit Ethernet TP network connection⎯ The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of100 meters. Cat. 5e is recommended.2-1-3-2. Cabling Requirements for 1000SX/LX SFP ModuleIt is more complex and comprehensive contrast to TP cabling in the fibermedia. Basically, there are two categories of fiber, multi mode (MM) and singlemode (SM). The later is categorized into several classes by the distance it supports.They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, theremainly are LC and BIDI LC.⎯⎯⎯⎯Gigabit Fiber with multi-mode LC SFP moduleGigabit Fiber with single-mode LC SFP moduleGigabit Fiber with BiDi LC 1310nm SFP moduleGigabit Fiber with BiDi LC 1550nm SFP moduleThe following table lists the types of fiber that we support and those else notlisted here are available upon request.Multi-mode Fiber Cable and Modal BandwidthIEEE 802.3zGigabit Ethernet1000SX 850nm1000Base-LX/LHX/XD/ZX1000Base-LXSingle Fiber(BIDI LC)Multi-mode 62.5/125μm Multi-mode 50/125μmModalModalDistanceDistanceBandwidthBandwidth160MHz-Km 220m 400MHz-Km 500m200MHz-Km 275m 500MHz-Km 550mSingle-mode Fiber 9/125μmSingle-mode transceiver 1310nm 10KmSingle-mode transceiver 1550nm 30, 50KmSingle-ModeTX(Transmit) 1310nm*20Km RX(Receive) 1550nmSingle-ModeTX(Transmit) 1550nm*20Km RX(Receive) 1310nmTable2-112
2-1-3-3. Switch Cascading in Topology• Takes the Delay Time into AccountTheoretically, the switch partitions the collision domain for each port in switchcascading that you may up-link the switches unlimitedly. In practice, the networkextension (cascading levels & overall diameter) must follow the constraint of theIEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in whichthe limitations are the timing requirement from physical signals defined by 802.3series specification of Media Access Control (MAC) and PHY, and timer from someOSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:1000Base-X TP, Fiber 100Base-TX TP 100Base-FX FiberRound trip Delay: 4096 Round trip Delay: 512Cat. 5 TP Wire: 11.12/m Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/mFiber Cable : 10.10/m TP to fiber Converter: 56Bit Time unit : 1ns (1sec./1000 Mega bit) Bit Time unit: 0.01μs (1sec./100 Mega bit)Table 2-2Sum up all elements’ bit-time delay and the overall bit-time delay ofwires/devices must be within Round Trip Delay (bit times) in a half-duplex networksegment (collision domain). For full-duplex operation, this will not be applied. Youmay use the TP-Fiber module to extend the TP node distance over fiber optic andprovide the long haul connection.• Typical Network Topology in DeploymentA hierarchical network with minimum levels of switch may reduce the timingdelay between server and client station. Basically, with this approach, it willminimize the number of switches in any one path; will lower the possibility ofnetwork loop and will improve network efficiency. If more than two switches areconnected in the same network, select one switch as Level 1 switch and connect allother switches to it at Level 2. Server/Host is recommended to connect to the Level1 switch. This is general if no VLAN or other special requirements are applied.13
