Arista Compatible 1000BASE LX SFP 1.25 G 1310nm 10km DOM LC SMF
Arista Compatible 1000BASE LX SFP 1.25 G 1310nm 10km DOM LC SMF
1000BASE-LX SFP 1310nm 10km DOM LC SMF Optical Transceiver Arista Compatible
Product Descriptions
The 1000BASE-LX SFP 1310nm 10km DOM LC SMF Optical Transceiver Arista Compatible applies to dual data-rate of 1.25Gbps/1.0625Gbps and 10km transmission distance with SMF and compatible with Arista. The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit.
Digital Diagnostic Specifications
The OLSP3112L-C(I)D10 transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.
| Parameter | Symbol | Units | Min. | Max. | Accuracy | Note |
| Transceiver temperature | DTemp-E | ºC | -45 | +90 | ±5ºC | 1 |
| Transceiver supply voltage | DVoltage | V | 2.8 | 4.0 | ±3% | |
| Transmitter bias current | DBias | mA | 2 | 15 | ±10% | 2 |
| Transmitter output power | DTx-Power | dBm | -10 | -2 | ±3dB | |
| Receiver average input power | DRx-Power | dBm | -25 | 0 | ±3dB |
Notes:
1. When Operating temp.=0~70 ºC,the range will be min=-5,Max=+75
2. The accuracy of the Tx bias current is 10% of the actual current from the laser driver to the laser
3. Internal/ External Calibration compatible.
Electrical Characteristics (TOP(C) = 0 to 70 ℃, TOP(I) =-40 to 85 ℃,VCC = 3.13 to 3.47 V)

Notes:
1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.
2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.
3. RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.
