H3C QSFP112-DR4-400G Compatible 400G QSFP112 DR4 Transceiver Module

Built with H3C compatibility coding, this 400GBASE-DR4 QSFP112 module supports parallel single-mode links in enterprise and data-center networks. It combines a 4x100G PAM4 host interface with a 1310nm DR4 optical interface and MPO-12/APC cabling up to 500m.

OEM / Compatible Part Number: QSFP112-DR4-400GHT Part Number: QSFP112-DR4-400G

Product Highlights

• 400GBASE-DR4 QSFP112 with 4x100G PAM4 electrical and optical lanes
• 1310nm parallel single-mode optics for reaches up to 500m
• MPO-12/APC optical connector with digital diagnostic monitoring
• 425Gbps aggregate line rate and hot-pluggable QSFP112 form factor
• H3C compatibility coding and factory link testing before shipment

The module can be used in QSFP112 switch ports and compatible network adapters for 400G spine-leaf, switch-to-server and AI-cluster connections. It can also interconnect with a matching 400G DR4 optical interface at the remote end when both sides use the same 4x100G PAM4 optical lane plan.

Use an MPO-12/APC single-mode jumper with the correct polarity for a direct 400G link. For 400G to 4x100G breakout applications, use suitable DR4-to-DR1 cabling and confirm that the host port, remote modules and software configuration all support breakout operation. Connector and splice losses must remain within the link budget.

Before packing, we check H3C compatibility identification, EEPROM readout and link establishment on the intended platform profile. Optical transmit power, receiver readings and diagnostic information are inspected as part of the factory test process. Provide the exact host model and software release when ordering if the installation has strict third-party optic requirements.

Quote HT part number QSFP112-DR4-400G, the selected compatibility version H3C and compatible part number QSFP112-DR4-400G, together with the required quantity. For mixed-brand networks, order each host-specific version separately rather than moving one programmed module between different equipment brands.

Each unit receives compatibility, optical-performance and visual checks before shipment. Modules are packed in anti-static protective trays and cartons; project labels and customized packing lists are available for volume orders.

Standard products normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
