What is FEC (Forward Error Correction)?

FEC (Forward Error Correction) is an error correction technique that detects and corrects a limited number of errors in transmitted data without retransmission. It works by adding redundant bits to the bit stream to help the decoder detect and correct some transmission errors without retransmission. This feature requires the transmission device to be turned on.

What are the main advantages of QSFP-100G-ER4?

With features such as high reception sensitivity, low power consumption, and high reliability, QSFP-100-ER4 optical modules can help users eliminate relay optical amplification equipment, thus reducing operating costs and providing a low-cost solution for long-distance applications between 100G ports between server rooms.

Questions & Answers

Ask a Question

How does the QSFP-100G-ER4 work?

The 100G ER4 enables transmission distances of up to 40km by using a semiconductor amplifier (SOA) inside the transceiver to increase the power budget. The transmitter can operate on four LAN WDM bands: 1296nm, 1300nm, 1305nm and 1309nm. Optical signals on these four bands are multiplexed by a WDM WDM multiplexer and transmitted over single-mode fiber through a duplex LC connector. At the receiving end, the SOA amplifies the signal before the WDM WDM multiplexer breaks it down into individual channels.

What is the transmission distance of QSFP-100G-ER4?

The transmission distance is up to 30km without opening the port FEC and up to 40km with opening the port FEC.

What is the power consumption of QSFP-100G-ER4?

4.5W.
