Applications
The 200G QSFP56 LR4 Optical Transceiver is used in 200G Ethernet, data center interconnect and 5G transport networks, where it provides a 200Gbps link over SMF up to 10km. The Duplex LC/UPC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 4x50G-PAM4 modulation, which keeps it aligned with current 200G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE 802.3bs, QSFP56 MSA, SFF-8661. The unit works in any equipment with a standard QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
Order this product as QSFP-LR4-200G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
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.
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.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
