WRAP OPERATION FUNCTIONS - SOFT CONTROL (Address A2h, Byte 111).

To assist with local host or remote diagnostic and optimization sequences, electrical and optical wrap functions can be enabled. Optical wrap

(OWRAP) takes the received optical signal through CDRs and retransmits it optically out. Electrical wrap (EWRAP) takes the received

electrical signal through CDRs and retransmits it electrically out. Optional forward functions can be transmitted outbound the wrapped

information via i2c control.

OWRAP Forward

Enable Bit

When set in combination with OWRAP Enable, OWRAP Forward routes incoming

SFP+ Rx optical data to both the Tx optical output and the Rx electrical output.

Enabling sets bit 2 and clears all other bits in byte 111.

OWRAP Enable

Bit

When set, OWRAP routes incoming SFP+ Rx optical data to the Tx optical output.

Enabling clears all other bits in byte 111.

EWRAP Forward

Enable Bit

When set in combination with EWRAP Enable, EWRAP Forward routes incoming

SFP+ Tx electrical data to both Rx electrical output and Tx optical output. Enabling

sets bit 0 and clears all other bits in byte 111.
