SFP 10G LR

 T&S TSPP-31192-LR is a Series single-mode, Pluggable Fiber-Optical SFP for 10G Ethernet, compliant with the IEEE 802.3ae 10GBASE-LR/LW standards.

 

TSPP-31192-LR module is designed for single-mode fiber and operates at a nominal wavelength of 1310nm. The transmitter section uses a multiple quantum well DFB, which is class 1 laser compliant according to International Safety Standard IEC-60825.

 

The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.

Notes:

 

Module circuit ground is isolated from module chassis ground within the module.

 

should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15Vand 3.6V.

 

Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ pullup to VccT inside the module.

 

Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.

 

RS0 and RS1 are module inputs and are pulled low to VeeT with > 30 kΩ resistors in the module.
