Applications
The 400G QSFP112 LR4 Optical Transceiver is used in 400G Ethernet data center and cloud network environments, where it provides a 425Gbps (4x106.25Gb/s) link over SMF up to 10km. With its Duplex LC UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
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.
Ordering Information
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
Tested Before Shipment
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.
