M R V C o mmu n i c a t i o n s , I n c . – I n s t a l l a t i o n M a n u a l Chapter 2 Site Survey The first step before every installation is to visit the sites to be linked. in order to make sure that the connection is feasible, to find out potential obstacles or difficulties and to decide on the location and mounting points of the transceivers. Line of Sight A necessary condition for linking two distant buildings is that the two mounting sites must be within clear sight of each other.

Avoid surfaces with high reflectivity (e.g., white walls) behind the TereScope so as to reduce interference with the optical signal. 4.

The only infrastructure required for operating the transceiver and linking the sites is Power and Data/Signal connection to the peripheral networking equipment. This must be ready prior to the airlink installation. IN OUTDOOR INSTALLATIONS, USE SHIELDED AND WEATHERPROOF MATERIALS (CABLES, INLETS, AND CONNECTORS) COMPLIANT TO THE SAFETY STANDARD IN FORCE.
M R V C o mmu n i c a t i o n s , I n c . – I n s t a l l a t i o n M a n u a l A simple power loss test can inform us about the condition of the fibers. This test consists in measuring (with an optical power meter) the output power at one end of the tested fiber when a fiber source is connected at the other end. If the values are in dBm, the difference between the input power and the output power gives the power attenuation of the fiber (in dB).

Accordingly, it is strongly recommended to perform a bench test with all the modules prior to installation in order to check the equipment compatibility and to validate the configuration.

The transceiver will be fixed on the top of the tower. Two techniques using a small concrete block are suggested for stabilizing the tower on the floor. • The concrete slab material is poured directly on the base of the tower • Four bolts are inserted in the concrete slab placed on the floor.

The bench test is a simple procedure whereby a link pair is aligned on the table and activated to simulate a channel of communication (see fig.1). 2 Points to Remember 1. Since the link distance during the bench test is very short (i.e.
M R V C o mmu n i c a t i o n s , I n c . – I n s t a l l a t i o n M a n u a l allows for testing each transmitter separately. By rotating the devices 45 degrees, the next pair of transmitters is tested. Hence, testing all 8 transmitters in the link pair requires only 4 rotations. In the 8” setup, the two devices are not centrally aligned; instead, only one corner of each device faces the opposite device. This allows for testing each transmitter separately.

M R V C o mmu n i c a t i o n s , APPENDIX F I n c . – I n s t a l l a t i o n M a n u a l Effect of Wind on Terescopes Introduction The outdoor environment in which our devices are normally placed exposes the link to wind pressures that may affect the accuracy of the link’s alignment.
M R V C o mmu n i c a t i o n s , Appendix G I n c . – I n s t a l l a t i o n M a n u a l FSO Chaining What is Chaining? The Chaining of FSO is required when the two sites are connected by more than one link using at least one additional building as a mid-point.
M R V C o mmu n i c a t i o n s , I n c . – I n s t a l l a t i o n M a n u a l Indirect Chaining Indirect Chaining is required for connecting FSO units not including clock recovery circuits. In cases of indirect connectivity, the connection between the two FSO units on the same roof must be done through the Switch or Router or another means of connection that is located inside the building. For example, in Fig. 2, we use the indoor switch in building C for the chaining. A C Fig. G.

If the extentions are of TDM type (E1,E3,STM-1, STM-3 ), after some chains we might face some “jitter”problems.

PoE eliminates a separate DC power supply cable at each Access Point (AP) location, i.e., it allows for a single Ethernet cable providing both data and power to be run to each AP instead of two separate cables, one for power and the other for data. There are two types of PoE connections.
