How many layers are used in an SFP optical module

A typical SFP fiber module consists of a cage, PCBA, chip, and TOSA+ROSA (sometimes maybe BOSA for BiDi transceiver). Figure 1: SFP module top and back viewIn the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks. Among various optical module form factors, SFP (Small Form-Factor Pluggable). Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. Engineers use SFPs to flexibly deploy 1G to 10G links over copper or fiber, opti...
