What type of connector does the QSFP-100G-PSM4 use?

According to the product category, the QSFP-100G-PSM4 is a 100GBASE-PSM4 parallel single-mode fiber module with an MPO-12 interface. This indicates it is designed to mate with MPO-12 terminated ribbon cabling, which is common in high-density backbone and structured cabling deployments using parallel single-mode fiber.

Which fiber type is compatible with the QSFP-100G-PSM4 module?

The module is described as a 100GBASE-PSM4 parallel single-mode fiber solution, indicating it is intended for use with single-mode fiber arranged in a parallel ribbon configuration. This classification guides planners to pair it with parallel single-mode MPO-12 cabling rather than multimode or duplex fiber types.

What form factor does the Arista QSFP-100G-PSM4 use?

The QSFP-100G-PSM4 belongs to the QSFP28 100G Ethernet optical module category. This identifies its mechanical format as QSFP28, which is widely used for 100G interfaces on data center and aggregation switches. Ensuring the host device has QSFP28 cages is essential for proper deployment.

Is the QSFP-100G-PSM4 suitable for 100G data center links?

Yes, it is classified as a QSFP28 100G Ethernet optical module using the 100GBASE-PSM4 standard over parallel single-mode fiber with MPO-12. These characteristics align well with typical 100G data center architectures that use QSFP28 ports, PSM4 optics and MPO-12 based structured cabling for high-bandwidth links.
