400G QSFP112 LR4 Optical Transceiver

Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP112 LR4 Optical Transceiver provides 425Gbps (4x106.25Gb/s) throughput in a QSFP112 form factor. It operates at 1310nm over SMF through a Duplex LC UPC connector and supports link lengths up to 10km. The module meets QSFP-112 MSA, CMIS Rev 5.2, 100G Lambda MSA-400GBASE-LR4-10, OIF-CEI-112G-VSR-PAM4 and includes digital diagnostic monitoring for live status readout.

Built for 400G Ethernet data center and cloud network environments, this QSFP112 module carries 425Gbps (4x106.25Gb/s) over SMF up to 10km per link. With its Duplex LC UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 4x100G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: QSFP-112 MSA, CMIS Rev 5.2, 100G Lambda MSA-400GBASE-LR4-10, OIF-CEI-112G-VSR-PAM4. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.

Our part number for this module is QSFP112-LR4-400G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
