31、 module. Fibre optic transceiver modules are classified into 5 types of forms according to the combination of mating types of electrical and optical interfaces. Details are described in IEC 62148-1. The 5 types are as follows: Type 1: Fibre optic connector interface with direct solderable type elect
32、rical terminals. Type 2: Fibre optic connector interface with plug-in type electrical terminals. Type 3: Fibre optic pigtail interface with direct solderable type electrical terminals. Type 4: Fibre optic pigtail interface with plug-in type electrical terminals. Type 5: Modules are not classified in
33、to type 1 type 4. (A typical example is a module that has both electrical connectors and non-connector type terminals as an electrical interface such as a coaxial connector for signal and lead terminals for the power supply.) 5 Optical interface 5.1 General The intent of this document is to adequate
