10g finisar sfp+ transceivers  

Description

1.Rollball’s 10Gigabit SFP+ transceiver is designed to transmit and receive optical data over single mode optical fiber up to 40km. 

2.The SFP+ module electrical interface is compliant to SFI electrical specifications.  The transmitter input and receiver output impedance is 100 Ohms differential.  Data lines are internally AC coupled.  The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI.  SFI typically operates over 200 mm of improved FR4 material or up to about 150mmof standard FR4 with one connector.

3.The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 10GBASE-SR/LR/ER standard.  An open collector compatible Transmit Disable (Tx_Dis) is provided.  A logic “1,” or no connection on this pin will disable the laser from transmitting.  A logic “0” on this pin provides normal operation. 

4.The transmitter has an internal automatic power control loop (APC) to ensure constant optical power output across supply voltage and temperature variations.  An open collector compatible Transmit Fault (TFault) is provided.  TX_Fault is a module output contact that when high, indicates that the module transmitter has detected a fault condition related to laser operation or safety.  The TX_Fault output contact is an open drain/collector and shall be pulled up to the Vcc_Host in the host with a resistor in the range 4.7-10 kΩ.   TX_Disable is a module input contact. When TX_Disable is asserted high or left open, the SFP+ module transmitter output shall be turned off. This contact shall be pulled up to VccT with a 4.7 kΩ to 10 kΩ resistor.
