Applications
Built for 100G Ethernet, data center interconnect and 5G transport networks, this QSFP28 module carries 100Gbps over MMF up to 70m@OM3/100m@OM4 per link. With its MPO-12/UPC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. For networks standardized on Arista Networks hardware, it is a drop-in equivalent of the QSFP-100G-SR4-E. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Arista Networks part QSFP-100G-SR4-E and works in Arista Networks systems out of the box. Standards compliance covers IEEE 802.3bm, 100GBASE-SR4, SFF-8636.
Ordering Information
Order this product as QSFP-SR4-100G-E-ARISTA. 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.
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.
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
