Note 1:

There are CMOs devices in this chip, so pay attention to prevent static electricity during transportation and useThe device should be grounded well to reduce parasitic inductance.Try to solder by hand, if you need machine stickers, control reflow temperature can not exceed 205 degreesCelsius.

Do not lay copper under the optical module to prevent impedance changesThe antenna should be kept away from other circuits to prevent the radiation efficiency from becoming low oraffect the normal use of other circuits.

Module placement should be as far away as possible from other low frequency circuits, digital circuitslt is recommended to use magnetic beads for isolation of the module's power supply.

Note 2:

You cannot directly look at the optical module (whether long-distance or short-range optical module) that hasbeen plugged into the device to avoid eye burns.With a long-distance optical module, the transmitted optical power is generally greater than the overload opticapower. Therefore, it is necessary to pay attention to the length of the optical fiber to ensure that the actualreceived optical power is less than the overload optical power, lf the lenath of the optical fiber is short, you neecto use the long-distance optical module to cooperate with the optical attenuation. Be careful not to burn theoptical module.

n order to better protect the cleaning of the optical module, it is recommended to plug the dust plug when not inuse. If the optical contacts are not clean. it may affect the sianal cuality and may cause link problems and bit

errors.The optical module is generally marked with Rx/Tx, or an arrow in and out to facilitate identification of thetransceiver, The Tx at one end must be connected to the Rx at the other end, otherwise the two ends cannot beinked
