This topic describes the types and specifications of pluggable optical modules supported by the MA5818.
The MA5818 supports optical modules of small form-factor pluggable (SFP) and enhanced small form-factor pluggable (eSFP) encapsulation modes. SFP and eSFP optical modules have the same dimensions and appearance. Unlike SFP optical modules, eSFP optical modules support performance statistics reporting.
The MA5818 supports optical modules with LC/PC and SC/PC connectors. Figure 1 shows the appearance of these optical modules.
