... The PECL interface is a stan- dard interface used by fiber optic transceivers in FDDI and 100Base-FX applications. Since 100Base-TX employs the basic TP-FDDI PMD scheme, the PE-68531G and PE-68537G are electrically identical with different RJ-45 pinouts as per the standards (refer to pinout specification). The PE-68537G fits the ...
