100G QSFP28 Modules: FAQs

Q: What compatible brands of FS QSFP28 modules are available?

A: FS offers high-quality 100G QSFP28 transceivers that are compatible with mainstream brands including Cisco, Arista, Juniper, Brocade, Dell, Extreme, HW, H3C, Ciena, Mellanox, IBM, Generic, FS, Edge-Core, Palo Alto Networks, Avago, Allied Telesis, Check Point, Chelsio, F5 Networks, etc.

Q: What's the difference between FS QSFP-100G-ER4L-S and QSFP-100/112G-ER4 transceiver?

A: QSFP-100G-ER4L-S QSFP28 transceiver module is designed for use in 100GBASE Ethernet throughput up to 40km over single mode LC fiber cable. While the QSFP-100/112G-ER4 QSFP28 is a dual rate optical transceiver, supporting data rate of 103.1Gbps and 112Gbps. It is suitable to be used in various applications, such as 100GBASE Ethernet, telecom, 5G network mid/backhaul.

Q: What's the difference between FS QSFP-100G-PSM4-S and QSFP-100G-CWDM4-S?

A: QSFP-100G-CWDM4-S optical transceiver is designed with LC duplex connector, supporting the maximum transmission distance up to 2km. While QSFP-100G-PSM4-S optics is designed with MTP/MPO connector and the maximum transmission distance is 500m. Usually QSFP-100G-CWDM4-S module is more expensive than QSFP-100G-PSM4-S module. But FS 100G CWDM4 transceiver has a special pricing now, just $189.

Q: Will FS 100GBASE-ER4 QSFP28 optical transceiver module work on a CWDM or DWDM Mux/Demux?

A: No. CWDM or DWDM Mux/Demux only support CWDM or DWDM transceiver. So our 100G ER4 module cannot be used directly with the 1310 channel port of CWDM Mux/Demux, because of its much greater working bandwidth than that of the channel port. But it is possible to transmit 100G data through the special port (provided that there is one on your device).
