Description

SFP+LR DWDM Transceiver is a ”Limiting module”, designed for 10GBASE-LR, and 2G/4G/8G/10G Fiber-Channel applications.

The transceiver consists of two sections: The transmitter section incorporates a DFB laser. And the receiver section consists of a PIN photodiode integrated with a TIA. All modules satisfy class I laser safety requirements. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power, and transceiver supply voltage.

Applications

• 10GBASE-LR at 10.3125Gbps
• Other optical links
• 10G Ethernet
• For the OBSAI application, the rates are 6.144Gb/s, 3.072 Gb/s, 1.536 Gb/s, and 0.768 Gb/s.
• For the CPRI application, the rates are 6.144Gb/s, 3.072 Gb/s, 2.4576 Gb/s, 1.2288 Gb/s, 0.6144 Gb/s

Notes

• The module circuit ground is isolated from the module chassis ground within the module.
• Should be pulled up with 4.7k-10k ohms on the host board to a voltage between 3.15V and 3.6V.
• Tx_Disable is an input contact with a 4.7 kΩto 10kΩ pull up 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 of 4.7 kΩ to 10 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.
