Applications

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. With its MTP/MPO-12 APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. 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. The link runs 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

Standards and Compatibility

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.

Ordering Information

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.
