Applications
The 40G QSFP+ QSFP-40G-SR4 150m 850nm MPO-12/UPC Module, Cisco is used in 40G Ethernet data center and enterprise network environments, where it provides a 41.25Gbps (4x 10.3125Gbps) link over twinax copper up to 150m@OM4/100m@OM3. The MTP/MPO-12 Male interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-40G-SR4.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-40G-SR4 and works in Cisco systems out of the box. Standards compliance covers IEEE 802.3 40GBASE-SR4, QSFP+ MSA, SFF-8436.
Ordering Information
To order, quote QSFP-4X10G-SR together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
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.
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.
