Applications
Network architects choose the 100G QSFP28 LR4 4x 25G NRZ 1310nm 10km Duplex LC/UPC Industrial Module, Cisco for 100G Ethernet, data center interconnect and 5G transport networks: it runs 103.125Gbps (4x 25.78Gbps) over SMF and reaches 10km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-100G-LR4-I directly.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-100G-LR4-I and works in Cisco systems out of the box. Standards compliance covers IEEE 802.3ba 100GBASE-LR4, IEEE 802.3bm, QSFP28 MSA Compliant.
Ordering Information
Our part number for this module is QSFP-LR4-100G-I. 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.
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.
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.
