Module Definition 2. Bi-directional data pin of two wire serial ID  
interface. This pin is open-drain and may be wired-ORed with other  
open-drain or open-collector devices.  
Module Definition 1. Clock pin of two wire serial ID interface. Data is  
clocked into EEPROM device on the positive edge and clocked out on  
the negative edge.  
Module Definition 0. Grounded internally. Used to notify host system  
that an SFP is present.

Rate Select  
RLOS  
Not supported in STM1E-SFPxx. Floating internally.  
Receive Loss of Signal. Asserted when the received signal is less than  
approximately 19dB below nominal for 110 UI. The RLOS condition is  
cleared when the received signal is greater than approximately 18dB  
below nominal for 110 UI.

Notes:  
1. Transmit and Receive grounds are connected directly together internally. For STM1E-SFP08 version,  
circuit grounds are also connected to frame/chassis ground.  
2. During Rx LOS conditions, the receive data outputs RD+/- are squelched. See Receiver Loss of Signal  
Condition section for more information on LOS detection for STM-1e interfaces.  
3. Transmit and Receive power supplies are connected together internally.
