OSN3500 dual-slot veneer Example:N1PEG16Dimensions: (H)261.4 mm x(D)235.2 mm x(W)50.3 mmThe following points should be noted during installation of the veneer forSDHequipment:

( 1 ) Wear anti-static wrist or gloves when holding the veneer, and ensure that the anti-static wrist is well grounded to prevent static electricity from damaging the veneer.

( 2 ) It is strictly prohibited to close or look directly at the optical interface board and the interface of the optical fiber. The laser beams inside the optical interface and optical fiber can damage your eyes.

( 4 ) Straight out of the optical module can not be directly connected to the optical attenuator, if you need the optical attenuator, can be added tothe ODFframe.

( 5 ) For the single board that can add optical attenuator, the optical attenuator can only be added to the "IN" port, not to the "OUT" port.

( 6 ) Optical interface loopback needs to add light attenuation to avoid damage to the optical module.

The bar code on the veneer panel of Huawei' s SDH equipment contains the veneer version, veneer name, and veneer characteristic code corresponding to the veneer characteristics.OSN3500has two types of bar codes:16-bit manufacturing code+veneer version+veneer name+veneercharacteristic code and20-bit manufacturing code+veneer version+veneername+veneer characteristic code. Take theOSN3500device16-digit manufacturing code barcode036440 1055000015 -SSN3 SL16A 01for example, which representsthe last six digits of theBOMcode, internal code, veneer version, veneer name and veneer characteristic coderespectively.
