1. According to the fiber type , 9/125um this data is a important feature of singlemode fiber , now most been used for making fiber optic patch cord singlemode fiber have 3 type : G657A1 , G652A2 and G652D etc .
Compare singlemode fiber , multimode fiber usually have 2 important data features , 50/125um or 62.5/125um . 50/125um multimode fiber and 62.5/125um multimode fiber all widely applied , depends on customers choices .
And in multimode fiber , some type fiber is special , one type is OM3 fiber (10GB fiber ). The OM3 fiber optic cable transmission distance can up to 300M . OM3 fiber most been used type is OM3-150 and OM3-300 type . And other special multimode fiber is OM4 fiber , the transmission distance better than OM3 fiber optic cable .
2. According to the patch cord color , the singlemode fiber optic patch cord , most color is yellow , the multimode fiber optic patch cord , most color is orange ,
OM3 fiber optic patch cord , most color is aqua , OM4 fiber optic patch cord usually purple .
3. According the label , singlemode fiber optic patch cord usually have a abbreviation to “ SM “ to indicate this is singlemode fiber , multimode will abbreviate “MM” .
OM3 fiber and OM4 fiber are special multimode , will remark directly , OM3 and OM4 .
