Section 3-6 Network Installation Outdoor Installations The following example shows how fiber-optic cable can be used to connect a network between two buildings, eliminating possible adverse affects of lightning. Node Node Noise-prone environment Coaxial cable Transceiver Transceiver Segment 2 Segment 1 Coaxial cable Transceiver Coaxial cable Transceiver Fiber-optic cable Noise-prone environment Optical transceiver Repeater Optical transceiver Repeater Note Contact the manufacturer for details on optical fiber devices. CS1W-FLN12 (10Base-T) Precautions Precautions on Laying Twisted-pair Cable Basic Precautions • Press the cable connector in firmly until it locks into place at both the hub and the FL-net (Ver. 2.00) Unit. • After laying the twisted-pair cable, check the connection with a 10Base-T cable tester. Environment Precautions • The twisted-pair cable for 10Base-T is not shielded, and the hub is designed for use in OA environments. In environments subject to noise, we recommend the use of 10Base-5 Ethernet. • Do not lay the twisted-pair cable together with high-voltage lines. • Do not lay the twisted-pair cable near devices that generate noise. • Do not lay the twisted-pair cable in locations subject to high temperatures or high humidity. • Do not lay the twisted-pair cable in locations subject to excessive dirt and dust or to oil mist or other contaminants. Hub Installation Precautions Environment Precautions • Do not install the hub near devices that generate noise. • Do not install the hub in locations subject to high temperatures or high humidity. • Do not install the hub in locations subject to excessive dirt and dust or to oil mist or other contaminants. 41
