Applications
Built for 100G Ethernet data center and enterprise network environments, this QSFP56 module carries 106.25 Gbps over MMF up to 100m per link. The MPO-12/UPC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 2x 50G PAM4 modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: QSFP56 MSA, SFF-8636, IEEE 802.3cd. 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 QSFP56-SR2-100G. 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.
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.
Delivery
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.
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.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
