Transceiver Alignment

General

Point-to-point connections require face-to-face orientation of both transceiving ends of the link. With wireless optical links, the beam spot should be positioned symmetrically on the remote receiver, as accurately as possible.

Successful installation of the TereScope depends primarily on precise and accurate optical alignment. Carefully follow the instructions below!!!

Tools and Equipment

Note

The customer can order patch cables and high-output portable source from

MRV.

The following tools and equipment are required at each link end:

A communication device (mobile phone or walkie-talkie)

Optical-power meter, giving readings in milliwatts/microwatts or dBm. (The Optical power meter is convenient though not necessary.)

JITK-L.

Procedure

Turn on the power to the TereScope heads from the power source.

Models TS700/155 ,TS700/100 and TS800/155: Set DIP switch toggles 1, 2 to the “Alignment” position (indicated on the back panel). In TS800 models set the SD2 DIP switch. In TS700/100 only DIP switch toggle 1.

Model TS700G: Even if the data port is left unconnected, the TereScope transmits an Idle Signal which can be used to perform alignment.

The transceiver alignment procedure is implemented in two stages:

#Coarse Alignment

#Fine Alignment

Coarse Alignment

1.Make sure that both axes (horizontal ‘G1’ and vertical ‘G2’) can turn freely (but you should’nt loosen or open the ‘G2’ screws). Loosen bolts F1 and K at least two turns and G1 aiming axis

loosen slightly. Loosen bolts D and bolts F2 on both sides of the

transceiver.
