Product description
The FTCS-BXX1X-40XX series single mode transceiver is small form factor pluggable module for duplex optical data communications such as 10GBASE-ER/LW defined by IEEE 802.3ae. It is with the SFP+ 20-pin connector to allow hot plug capability.
The FTCS-BXX1X-40XX module is designed for single mode fiber and operates at a nominal wavelength of 1270nm or 1330nm; 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:
[1] Module circuit ground is isolated from module chassis ground within the module.
[2].should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15Vand 3.6V.
[3]Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ pullup to VccT inside the module.
[4]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.
[5]RS0 and RS1 are module inputs and are pulled low to VeeT with > 30 kΩ resistors in the module.
