Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 ESR4 4x 25G NRZ QSFP-100G-SR4-S 850nm 300m MPO-12/UPC Module, Cisco delivers 103.125Gbps (4x 25.78Gbps) transmission over MMF with a reach of 200m@OM3/300m@OM4. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-100G-SR4-S. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: IEEE 802.3bm, QSFP28 MSA, SFF-8665, SFF-8636, SFF-8679. For projects standardized on Cisco hardware, this product replaces the QSFP-100G-SR4-S directly, with identical fit and function. 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 QSFP-ESR4-100G. 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.
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
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.
Quality Assurance
Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.
