Question：What type of information does TEKWAY Communications need to verify that that a customer is ordering the right type of equipment for their application?

Answer： There are 13 basic questions that typically need to be answetekway:

(1) What is the system topology? (e.g. point-to-point, bus/string, ring, self-healing ring...)

(2) What type of TEKWAY Communications device do you think you need (e.g. modem, multiplexer, converter, transceiver...)

(3) What type of fiber optic cable are you going to use? (e.g. multimode 850nm, 1300nm; single mode 1300nm, 1550nm...)

(4) What type of fiber optic connector are you using (e.g. ST, FC, SC, SMA...)

(5) How many fibers are between devices? (e.g. One - Simplex Transmission; One - Duplex Transmission; Two - Duplex Transmission; Three/RGB...)

(6) What is the distance between the devices you are connecting? (e.g. 2 kilometers, 20 kilometers...)

(7) What type of Electrical Interface are you using? (e.g RS-232, RS-366, RS-422, RS-449, RS-485 2-wire or 4-wire, RS-530, V.35, T1, E1, AUI, UTP/10BaseT, BNC/10Base2, Audio - 600 ohm, Video...)

(8) What clock type are you using? (e.g. Asynchronous; Synchronous - Internal or External Clock...)

(9) What Control Signals do you need? (e.g. RTS, CTS, DSR, DTR, CD...)

(10) What is your device type? (e.g. DTE or DCE)

(11) What is the transmission rate do you require? (e.g. 19.2 Kbps, 56 Kbps, 2048 Mbps...)

(12) What fiber optic loss budget do you require? (total of connector loss & attenuation plus safety margin [3dB] for a given fiber optic link). Typical loss budget for a device would be 17dB, 20dB, 25dB...)

(13) What type of power source do you require? (e.g. 12VDC, 24VDC, -48VDC, 220 VAC...)
