Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 LX4 4x 25G NRZ 1310nm 2km/100m Duplex LC/UPC Module, Cisco delivers 103.12Gbps (4x 25.78GGbps) transmission over SMF/MMF with a reach of 2km@SMF/100m@OM3 MMF. With its Duplex LC optical interface, the module works directly with the SMF/MMF 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 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Standards compliance covers IEEE Std 802.3bm-2015, SFF-8665 Rev 1.9, SFF-8636 Rev 2.10a, SFF-8679 Rev 1.8. The unit works in any equipment with a standard QSFP28 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-LX4-100G. 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.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
