<p>Methods and apparatus are described for forward baseband digitalization. A method includes receiving a forward baseband digital optical signal from an optical fiber; transforming the forward baseband digital optical signal to a forward analog electric signal; transmitting the forward analog electrical signal on the electrical conductor; transforming the reverse analog electrical signal to a reverse digital baseband optical signal; and transmitting the reverse digital baseband optical. An apparatus includes a forward baseband digital optical signal receiver; a forward circuit coupled to the forward baseband digital optical signal receiver, the forward circuit transforming a forward baseband digital optical signal to a forward analog electrical signal; a forward analog electrical signal transmitter coupled to the forward circuit; a reverse analog electric signal receiver; a reverse circuit coupled to the reverse analog electrical signal receiver, the reverse circuit transforming a reverse analog electrical signal to a reverse digital baseband optical signal; and a reverse baseband digital transmitter coupled to the reverse circuit, wherein transforming the forward baseband digital optical signal to the forward analog electrical signal includes combining a first sub-divided portion and a second subdivided portion.</p>
