Will the ER4 module work with the Intel switches?

Yes, you can choose #167801 with Intel devices.

We're looking to establish a 100g link over 35km of sm fiber. Can you confirm if this module is the correct part? And the switches we're using are Supermicro SSE-X3548S. Have you tested these transceivers with this link?

Based on your switch brand, we recommend you choose #167801. Additionally, our company can provide you with a test report for using the module to establish a 40km bare fiber connection on the switch.

Is the QSFP-ER4L-100G like the QSFP-ZR4-100G or the QSFP-4W40-100G-I?

Yes, there are many similarities to both the QSFP-ER4L-100G and QSFP-4W40-100G-I. Their maximum cable distances are 40km, but the QSFP-ZR4-100G which reaches 80km distance furthest has an SOA and platform-based RS-FEC.

I need a optical module that can transmit up to 9.5km. I want to confirm if the ER4 module must be used with the 70010 fiber attenuator? Can the single module meet my requirement for transmission distance?

Yes, if using the 100G ER4, it is necessary to add fiber attenuation #70010 based on the link condition, which help prevent receiver overload and damage to the optical module.

Can I test the specific power consumption of the product myself?

Yes, you can use the beta to test power consumption.

What is FEC (Forward Error Correction)?

FEC (Forward Error Correction) is an error correction technique to detect and correct a limited number of errors in transmitted data without the need for retransmission. It works by adding redundant bits to a bitstream to help the decoder detect and correct some transmission errors without the need for retransmission. This function needs to be turned on by the transmission device.
