Line up（9）
| Model number | overview |
|---|---|
| DEM Series (100G Optical Transceiver) | This series is a QSFP28 optical transceiver that connects to a 100 Gigabit switch with QSFP28 ports, enabling ultra-fast, high-capacity communication over medium to long distances. Thanks to high-density implementation technology, it is compact and low-cost, making it ideal for connections between backbones. This series supports 100GBASE-SR4/100GBASE-LR4. |
| DEM Series (40G Optical Transceiver) | This is a QSFP+ optical transceiver that connects to a 40 Gigabit switch with QSFP+ ports, enabling ultra-fast, high-capacity communication over medium to long distances. With high-density implementation technology, it is compact and low-cost, making it ideal for connections between backbones. This series supports 40GBASE-SR4/40GBASE-LR4. |
| DEM Series (10G Optical Transceiver) | This is an SFP+ optical transceiver that connects to a 10 Gigabit switch with SFP+ ports, enabling ultra-fast, high-capacity communication over medium to long distances. Thanks to high-density implementation technology, it is compact and low-cost, making it ideal for connections between backbones. This series supports 10GBASE-SR/LR/ER/LR/ZR/LRM. |
| DEM Series (10G Copper SFP+) | This is a 10Giga Copper SFP+ transceiver that easily expands to a 10GBASE-T compatible port simply by being mounted on a switch with an SFP+ slot. |
| DEM Series (1G Optical Transceiver) | This is a 1Giga SFP optical transceiver that easily expands to a high-speed long-distance optical port simply by being mounted on a switch with an SFP slot. By selecting the optical transceiver according to the specifications of the connected optical communication device, it enables flexible network design and operation. |
| DEM Series (WDM Compatible 1G Optical Transceiver) | This is a WDM (Wavelength Division Multiplexing) compatible SFP optical transceiver that connects a gigabit switch with an SFP (Mini-GBIC) slot to an optical network. It allows simultaneous transmission of multiple optical signals with different wavelengths over a single optical fiber, enabling bidirectional transmission of digital optical signals. |
| DEM Series (100M Optical Transceiver) | This is a 100M SFP optical transceiver that easily expands to a high-speed long-distance optical port simply by being mounted on a switch with an SFP slot. By connecting to the optical port of a compatible switch's SFP slot, it allows easy introduction of optical communication into your network environment. |
| Direct Attach Cable | This is an interface cable with optical transceiver shapes on both ends. It is used to connect devices over short distances by being mounted on the SFP+ slot of the device itself. It is intended for use in stack connection applications of stackable switches that can accommodate optical transceivers. |
| CX4 Cable (For DGS-3120 Series Only) | This is a 10G CX4 cable intended for use in stack connection applications between DGS-3120 series devices. |
