10G SFP+ CWDM 光模块,10KM (1260~1620nm)

DESCRIPTION
This CWDM DFB  10Gigabit SFP+ transceiver is designed to transmit and receive optical data over single mode optical fiber for link length 10km.
The  SFP+   LR  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.
The transmitter converts 10Gbit/s serial CML electrical data into serial optical data compliant with the 10GBASELR standard.   An open collector compatible Transmit Disable (TxDis) 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.   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. TXFault 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 TXFault output contact is an open drain/collector and shall be pulled up to the VccHost in the host with a resistor in the range 4.7-10 kΩ .   TXDisable is a module input contact. When TXDisable 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
The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data.An open collector compatible Loss of Signal is provided.  RxLOS when high indicates an optical signal level below that specified in the relevant standard.   The  RxLOS contact  is an open drain/collector output and shall be pulled up to VccHost in the host with a resistor in the range 4.7-10 kΩ, or with an active termination.   Power supply filtering is recommended for both the transmitter and receiver.    The  RxLOS signal  is  intended as a preliminary indication to the system in which the SFP+ is installed that the received signal strength is below the specified range. Such an indication typically points to non-installed cables, broken cables, or a disabled, failing or a powered off transmitter at the far end of the cable.
