400GBASE-SR4 OSFP112 Optical Module: 400G-OSFP112-100
400G OSFP112 SR4 Transceiver Overview
The 400GBASE-SR4 OSFP112 Optical Module is a 400 Gigabit Ethernet optical transceiver in the OSFP112 form factor, built for parallel multimode fiber connections up to 100 meters. It uses the 400GAUI-4 electrical interface across four lanes of 106.25 Gbps PAM4 SerDes and a Flat-Top (RHS) OSFP112 mechanical profile. Optically, it carries four lanes of 850nm PAM4 traffic over multimode fiber through an MTP/MPO-12 APC connector, with digital diagnostic monitoring, host FEC and CDR support. The module targets OSFP112 host systems specifically; it is not mechanically compatible with QSFP112 cages.

400GBASE-SR4 OSFP112 Optical Module Description
The 400GBASE-SR4 OSFP112 Optical Module is a 400 Gigabit Ethernet transceiver built on the OSFP112 form factor for parallel multimode fiber links up to 100 meters, with a maximum data rate of 425 Gbps at PAM4 modulation.
This module uses the 400GAUI-4 electrical interface, four lanes at 106.25 Gbps PAM4 per lane, and a Flat-Top (RHS) OSFP112 top type. OSFP112 is the four-lane host interface within the OSFP MSA family and is mechanically distinct from QSFP112, so this module is intended for OSFP112 host systems only. Host FEC and CDR are supported.
On the optical side, four lanes of multimode fiber carry the signal at 850nm across a 19nm wavelength band through a single MTP/MPO-12 APC connector with 8 fibers, 4 transmit and 4 receive. A VCSEL laser transmitter and PIN photodiode receiver pair each lane, with a 2.5 dB minimum extinction ratio. Average launch power spans -4.6 dBm to 4 dBm per lane, and average receiver sensitivity spans -6.4 dBm to 4 dBm per lane.
Average link budget is 1.8 dB, with a maximum reach of 100 meters over multimode fiber. Operating temperature is standard 0 to 70C, storage runs -40 to 85C, and power draw is bounded at 8W on a 3.3V supply. Compliance covers CE, RoHS, IEEE 802.3db, CMIS V5.1, OSFP MSA, Class 1 FDA and IEC 60825-1 laser safety.
Digital diagnostic monitoring reports real-time operating parameters for each lane. This supports link health checks in OSFP112 deployments where 400G Ethernet spine and leaf connections rely on parallel multimode fiber runs.
This module is made to order and carries EDGE Optical Solutions' standard 5-year warranty against defects in materials and workmanship. For project-quantity pricing or OSFP112 platform questions, contact our sales team.
Frequently Asked Questions
What is the difference between OSFP112 and OSFP, and which electrical interface does this module use?
OSFP112 is the four-lane variant within the OSFP MSA family, using the 400GAUI-4 electrical interface with four lanes of 106.25 Gbps PAM4 SerDes. This differs from the eight-lane 400GAUI-8 interface used on standard OSFP modules. OSFP112 cages are mechanically distinct from QSFP112 and QSFP-DD cages, so this module is intended for OSFP112 host systems only.
Does 400GBASE-SR4 reach the same distance over OM3 and OM4 multimode fiber?
The 400GBASE-SR4 application is documented to reach at least 100 meters over multimode fiber, with OM3, OM4 and OM5 grades falling under that same reach specification. Confirm the exact fiber-grade reach figures against the applicable IEEE 802.3db clause tables before finalizing link design.
Does 400GBASE-SR4 require host-side FEC?
Yes. This module supports host FEC on the 400GAUI-4 electrical interface, consistent with the FEC requirement for 106.25 Gbps-class PAM4 lanes in the 400GBASE-SR4 application. Confirm the host port's FEC configuration during commissioning.
Does this 400G OSFP112 SR4 module use an MPO-12/APC connector?
Yes. The module terminates through a single MTP/MPO-12 APC connector carrying 8 fibers, 4 for transmit and 4 for receive, matching the parallel multimode fiber structure of the 400GBASE-SR4 application.
