100G QSFP28 PSM4 4x 25G NRZ QSFP-100G-PSM4-S 1310nm 500m MPO-12/APC Module, Cisco

Designed for 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 PSM4 4x 25G NRZ QSFP-100G-PSM4-S 1310nm 500m MPO-12/APC Module, Cisco provides 103.125Gbps (4x 25.78Gbps) throughput in a QSFP28 form factor. It operates at 1310nm over SMF through a MTP/MPO-12 APC connector and supports link lengths up to 500m@OS2. The module meets QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, CAUI-4 and includes digital diagnostic monitoring for live status readout.

The 100G QSFP28 PSM4 4x 25G NRZ QSFP-100G-PSM4-S 1310nm 500m MPO-12/APC Module, Cisco is used in 100G Ethernet, data center interconnect and 5G transport networks, where it provides a 103.125Gbps (4x 25.78Gbps) link over SMF up to 500m@OS2. The MTP/MPO-12 APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. 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-PSM4-S.

Compliance: QSFP28 MSA, SFF-8636, IEEE 802.3‑2012, CAUI-4. For projects standardized on Cisco hardware, this product replaces the QSFP-100G-PSM4-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.

Our part number for this module is QSFP-PSM4-100G-CISCO. 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.

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.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.
