Generic Compatible 800GBASE-2xDR4 QSFP-DD 8x100G PAM4 1310nm 500m SMF DOM Dual MPO-12/APC Optical Transceiver Module

The Generic Compatible 800GBASE-2xDR4 QSFP-DD Optical Transceiver Module is engineered for next-generation 800G Ethernet networks, delivering high-capacity optical connectivity for advanced data center and cloud infrastructure. Based on PAM4 modulation, it combines two independent 400G DR4 optical channels to provide an aggregate bandwidth of 800Gbps. Each channel carries four 100G optical lanes, forming an 8×100G transmission architecture over single-mode fiber.

Operating at a nominal wavelength of 1310nm, the module supports transmission distances of up to 500 meters over SMF. Its dual MPO-12/APC optical interfaces provide separate connections for the two 400G DR4 channels, allowing the module to accommodate different network topologies and interconnection requirements. This architecture supports both native 800G optical links and 800G-to-2×400G breakout configurations when paired with compatible networking equipment.

Designed for QSFP-DD host platforms, the module follows the QSFP-DD MSA and relevant IEEE 802.3 optical interface specifications, with CMIS 5.0 support for standardized module management.

Questions & Answers

QSFP-DD-800G-2xDR4: Frequently Asked Questions

Q: Can this QSFP-DD 800G 2xDR4 module interoperate with an OSFP 800G 2xDR4 optical transceiver?

A: Yes. It can establish an 800G optical link with a compatible OSFP 800G 2xDR4 transceiver, provided that both devices support matching optical specifications, lane mapping, and link configurations. For 800G connectivity, both MPO-12/APC interfaces must be connected using two compatible single-mode fiber patch cords. It can also connect to two separate 400G DR4 transceivers for 800G-to-2×400G breakout applications.

Q: Can this module operate normally if only one MPO-12/APC port is connected?

A: Yes. The two MPO-12/APC interfaces support independent 400G DR4 optical links. When only one interface is connected to a compatible 400G DR4 transceiver, the corresponding 400G channel can operate independently, while the other channel remains unused. The active connection supports up to 400Gbps, subject to host device configuration and platform compatibility.

Q: Does this module support 800G-to-2×400G breakout connectivity? How does it work?

A: Yes. The module supports 800G-to-2×400G breakout applications by connecting its two independent MPO-12/APC interfaces to two separate 400G DR4 optical transceivers. Each interface carries one 400G optical link, allowing a single 800G host port to connect to two 400G network ports. The host switch must support the corresponding breakout configuration.

Q: Can an 800G 2xDR4 module directly interconnect with a single-port 800G DR8 module?

A: No, not through a direct optical connection. The 800G 2xDR4 architecture uses two independent 400G DR4 optical interfaces, whereas a conventional 800G DR8 architecture uses a single 8-lane optical interface, typically with an MPO-16 connector. Their optical lane mapping and connector configurations are different. Direct interoperability is therefore not supported without an appropriate optical conversion or breakout solution.
