Answers to Frequently Asked Questions About Fiber Optics

Yes. VERSITRON products meet the requirements of IEEE 802.3 (and others). As long as the equipment they are being linked to also meets these same requirements, then compatibility is assured.
Look for the diameter markings on the outer jacket of the fiber cable. Markings such as “50/125” or “62.5/125” indicate multimode fiber. Markings such as “8/125” or “9/125” indicate singlemode fiber. See 2 minute video

Multimode fiber is generally used for fiber runs that are less then 2 km. Singlemode fiber is generally used for fiber runs greater than 2 km. The reason for this is that the inside diameter of the glass tube inside the cable is much smaller for singlemode fiber (8 or 9 micron) vs. multi-mode fiber (50 or 62.5 micron). The smaller the diameter, the less the light will bounce. This results in less optical loss and greater distance. See 2 minute video

You need to daisy-chain the control signal of each camera and then bring that signal into a video transmitter as one signal.
Please see the diagram below:

Since each camera has its own unique address, it can be called up individually by the controller system.

It is always the optic which is closest to the power connector.
AMI = SW3 positions 1 and 8 on
B8ZS = SW3 positions 1 and 8 off
No, our telephone modems are designed for analog phone applications.
Ask us for a “cable adapter”. This is a one meter length of cable with ST connectors on one end and SC connectors on the other end. This is a quick, cost-effective, and reliable solution.
SX (850nm) = 200m over 62.5/125 multimode fiber
500m over 50/125 multimode fiber

Loopback testing involves inputing a defined signal to a modem, and expecting to receive the same signal on the output of that modem. Some modems have a switch and/or jumper which enables copper loopback. For the F2238, both a loopback switch and jumper are present, which for proper operation both must be replaced when loopback testing is finished. Another method of loopback testing the optical circuitry involves looping a piece of patch fiber from the transmitter to the receiver. If a data analyzer is both transmitting and receiving data to a modem in loopback, no errors should be occurring. If applicable, in loopback mode there should be no alarm light present on the modem.

Yes. The F22xx, F28xx, and MicroModem products show only one stream of data and one stream for clock. However, those 2 channels operate independently, and can be used for 2 clocks or 2 data channels if necessary. Also, control lines RTS / CTS and DTR / DSR can be used for lower speed data paths as well, provided those control signals are not required. Control lines operate independent of other channels as well. Using all channels, those modems will support 4 channels in each direction. Consult the product manual for specified data rates on a given channel.

Yes. Our serial modems are designed in such a way as to maintain DCE and DTE interface requirements. By selecting your modem type and, if desirable, using a standard null-modem cable, our products do not require any re-wiring to interface with systems following RS-530 and RS-232 standards.
