[0012] Further, the number of the metal structures fixed on each side of the optical fiber array body is at least one.

[0013] Further, the metal structures are fixed on the sides of the optical fiber array body in an adhesive manner.

[0014] The further beneficial effect is that: the metal structures are fixed to the optical fiber array body in an adhesive manner, which is very convenient and does not damage the optical fiber array body.

[0015] Further, the metal structures are adhered to the sides of the optical fiber array body by black glue.

[0016] Further, the metal structures are made of Kovar alloy.

[0017] Further, the metal structures are metal blocks, metal sheets or metal plates.

[0018] Further, the optical fiber array body is a multi-channel optical fiber array.

[0019] Further, the multi-channel optical fiber array is a four-channel optical fiber array.

[0020] Based on the above technical solution, the utility model also provides an optical module, which comprises: a metal base and an optical fiber array, and the metal structures in the optical fiber array are fixed to the metal base by welding.

[0021] The further beneficial effect is that: since the metal structures are fixed on the sides of the optical fiber array body, the optical fiber array body and the metal base in the optical module can be pre-fixed by dispensing glue, the dispensing pre-fixing method remains consistent with the prior art, and then the metal structures and the metal base in the optical module are fixed by welding, that is, no black glue is dispensed between the optical fiber array body and the metal base in the optical module, the fixing efficiency is effectively improved, the fixed optical fiber array is firm, and since no black glue is dispensed, the later repair is simple.
