100G CWDM4 module can be connected to 1310 special port of CWDM MUX for signal transmission, and the light transmission range of 1310 special port is ± 50nm (recommended #73959 ) Par FS le 10/02/2020

Thanks for your question. When using the transceivers, both ends need to open or close the FEC at the same time. If the FEC is turned off, the 100G CWDM4 transceiver also can be used in the case of compatibility. The main difference between turning the FEC on or off is that the FEC can be turned on to reduce the bit error rate. Par FS le 03/05/2019

Sorry, 100G QSFP28 transeivers that operate at an industrial temperature range are currently not available, but in development. Please stay tuned. Par FS le 17/02/2018

It is highly recommended that a data center facility implement cleaning procedures for all fiber optic connectors to reduce link failures and unnecessary replacement of expensive and critical network equipment. Fiberstore FOPC-301 LC/MU Cleaner is the best fiber cleaner for 100GBASE-IR4 QSFP28. Par FS le 10/06/2017

No. Network equipment manufacturers do not require that you use only name-brand optics. In fact, when a product fault or defect occurs in the network, and the fault or defect is not attributable to the use of third-party optics, they will continue to provide support for the affected product under warranty or covered by their support program.

We supply a huge volume of optics to a variety of customers, so in most cases we have all of the most popular optics in stock, ready to ship. However, some of the higher-value and specialized optics have a short lead time. You can find the stock information and the estimate delivery date from the product page easily, or contact sales@fs.com directly before you place the order. Par FS le 05/06/2017

The maximum power consumption of QSFP28-IR4-100G is 3.5W. All Fiberstore 100G QSFP switch ports are designed to handle QSFP transceivers that draw up to 4.5W. If a 100G QSFP28 draws greater than 4.5W FS cannot guarantee the performance since there are other dependencies like airflow direction, ambient temperature, elevation etc. Par FS le 03/06/2017

The Fiberstore 100GBASE-IR4 QSFP provides 100GBase-IR throughput up to 2km over single-mode fiber (SMF) using a duplex LC/UPC connector.The 100 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device. Par FS le 21/06/2017

The Fiberstore 100GBASE-IR4 QSFP Module supports link lengths of up to 2km over a standard pair of G.652 single-mode fiber (SMF) with duplex LC/UPC connectors. Par FS le 16/05/2017
