13. Inspection
Inspection items are as follows:
(1) Appearance
(2) Dimensions
(3) Optical output power
(4) Optical waveform
(5) Optical input power
a) Average sensitivity
b) Loss of Signal / Decreasing light input
c) Loss of Signal / Increasing light input
(6) Power supply current
14. Packing
The optical transceiver shall be packed in sturdy carton box(es) when shipping.
15. Caution
(1) Do not stare into optical output port although this product is designed to meet the class 1
laser regulation.
(2) The housing of the transceiver is possible to crack or dissolve against the particular
chemicals. Although we recommend to use the aqueous fluid in the cleaning, the below
chemicals are checked not to affect to the housing. Pay attention in the solder flux and
cleaning process. We recommend checking the appropriateness of the cleaning fluid in
advance.
/ methyl alcohol, ethyl alcohol, butyl alcohol, isopropyl alcohol, hexane, cyclohexane,
naphtha, tetrachloroethylene, propylene glycol
< Do not use : Chemicals which are checked to crack or dissolve>
/ trichloroethylene, trichloroethane, benzen, methyl ethyl ketone, chloroform, toluene,
acetone, phenol, ethyl acetate,
methylene di chloride
(3) Optical connectors should be cleaned completely by proper cleaning process before insertion to
optical receptacles of the transceiver to avoid contamination inside the optical receptacle.
The contamination may cause serious degradation of transmission performance. Using
forced nitrogen and some kind of cleaning stick ("CLE TOP, stick type" for LC/MU connector
supplied by NTT international is recommended) should be used if the receptacle get
contaminated by miss-treating optical connectors.
