400G OSFP112 DR4 Transceiver Overview

The 400GBASE-DR4 OSFP112 Optical Module is a 425 Gbps OSFP112 transceiver built on the 400GAUI-4 electrical interface (4x106.25G PAM4) and a Flat-Top (RHS) mechanical outline. It carries 400G Ethernet traffic over four lanes of single-mode fiber at 4x1310nm, terminated on an MTP/MPO-12 APC connector with 8 fibers, and targets a maximum reach of 500m. Average link budget is 3 dB, with a minimum optical budget (OMA) of 3.7 dB. Achievable distance depends on the connected fiber plant's attenuation and connector loss, so verify link budget against the deployed cable plant before committing to a full 500m span. The receiver uses PIN photodiode detection, with host FEC and CDR support built in. Digital diagnostic monitoring (DDM/DOM) reports per-lane transmit power, receive power, temperature, and voltage. The module operates across a standard 0C to 70C range on a +3.3V supply, drawing up to 8W, and follows the OSFP MSA mechanical and electrical outline, CMIS v5.2 management interface, and IEEE 802.3bs optical parameters for interoperability with OSFP112 host systems that adhere to the same MSA and CMIS revisions.

400GBASE-DR4 OSFP112 Optical Module Description

The 400GBASE-DR4 OSFP112 Optical Module targets 400G Ethernet (425 Gbps) on the OSFP112 form factor, using the 400GAUI-4 electrical interface (4x106.25G PAM4) in a Flat-Top (RHS) outline, per the IEEE 802.3bs 400GBASE-DR4 application across four lanes of parallel single-mode fiber at 4x1310nm.

It terminates on an MTP/MPO-12 APC connector with 8 fibers and targets a 500m reach over single-mode fiber, with a 3 dB average link budget and 3.7 dB minimum optical budget (OMA). Achievable distance depends on fiber-plant attenuation and connector loss; verify against the deployed cable plant. The receiver uses PIN photodiode detection.

Built-in host FEC and CDR support meet the RS-FEC framing 400GBASE-DR4 requires; both link ends need FEC enabled. The module follows the OSFP MSA mechanical and electrical specification and CMIS v5.2 management interface, interoperating with OSFP112 host systems on the same MSA and CMIS revisions.

Digital diagnostic monitoring (DDM/DOM) reports per-lane transmit power, receive power, temperature, and voltage. Operating range is a standard 0C to 70C, storage is -40C to 85C, and relative humidity runs 5 to 85 percent. Maximum power consumption is 8W from a +3.3V supply.

The module is CE and RoHS compliant and meets Class 1 FDA and IEC 60825-1 laser safety requirements, alongside IEEE 802.3bs, CMIS v5.2, and OSFP MSA compliance.

Typical deployments include top-of-rack to spine interconnects, high-performance computing fabrics, and DR4 breakout into four 100GBASE-DR duplex LC links. This module carries EDGE Optical Solutions' standard 5-year warranty against defects in materials and workmanship. For lead time, volume pricing, or platform verification, contact our sales team.

Frequently Asked Questions

What is the difference between OSFP112 and OSFP, and which electrical interface does this module use?

The OSFP MSA defines an outline with eight high-speed electrical lanes, supporting configurations from 400G (8x50G) up to 800G (8x100G). This module's OSFP112 designation refers to a 112G-class (106.25 Gbps actual) per-lane PAM4 electrical interface; it uses the 400GAUI-4 electrical interface, running 4 lanes at 106.25 Gbps PAM4 each, not the 8-lane 400GAUI-8 interface used on some other OSFP-family optics. Confirm which electrical interface the target host port expects before ordering.

Does this 400GBASE-DR4 OSFP112 module use an MPO-12/APC connector or duplex LC?

This module uses an MTP/MPO-12 APC connector with 8 active fibers, 4 transmit and 4 receive, for parallel single-mode fiber, as defined for the 400GBASE-DR4 application in IEEE 802.3bs. It does not use the duplex LC connector found on CWDM-based FR4 or LR4 modules. Confirm the correct connector and fiber count when planning cable runs.

Can this 400G OSFP112 DR4 module break out to 4x100GBASE-DR?

The module's four parallel lanes can be split through an MPO breakout harness into four 100GBASE-DR duplex LC links, a standard DR4 breakout pattern used in mixed-speed deployments. Confirm the breakout harness and far-end optics match the 100GBASE-DR specification before deployment.

Does 400GBASE-DR4 require host-side FEC?

Yes. Host FEC support matches the RS-FEC (KP4) requirement in IEEE 802.3bs for the 400GBASE-DR4 bit-error-rate target. Both ends of the link need FEC enabled consistently for the link to operate within spec.
