Applications

Network architects choose the 100/112G QSFP28 LR4&OTU4 4x 25G NRZ 1310nm 20km Duplex LC/UPC Dual Rate Module, Cisco for OTN transport, carrier metro and long-haul aggregation networks: it runs Dual Rate 103.1Gbps and 112Gbps over SMF and reaches 20km. 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. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

Standards and Compatibility

This product is designed and tested to comply with QSFP28 MSA, SFF-8636, IEEE 802.3bm, CAUI-4. It plugs into any standards-based QSFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.

Ordering Information

Our part number for this module is QSFP-ELR4-100GM. 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.

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.
