Transition Networks TN-QSFP-100G-SR4 QSFP28 100G SR4

Product Description

The TRANSITION NETWORKS TN-QSFP-100G-SR4 is a QSFP28 form-factor optical transceiver module designed for 100 Gigabit Ethernet transmission over multimode fiber. It conforms to the 100GBASE-SR4 standard, using four parallel lanes of 25 Gbps each to deliver an aggregate 100 Gbps link. The module supports a reach of 100 meters over OM4 multimode fiber and 70 meters over OM3 multimode fiber. It is intended for installation by network engineers and data center technicians working on high-density 100G switching and routing infrastructure.

This transceiver is suited for short-reach 100G interconnects in data centers, enterprise core switching environments, and high-performance computing deployments. Typical applications include top-of-rack switch uplinks, spine-to-leaf fabric connections, and server-to-switch direct connections over structured multimode cabling. The module ships as a single unit and is categorized as media conversion and fiber optic interface hardware.

Key Features

• 100GBASE-SR4 standard compliance for 100 Gbps parallel multimode fiber transmission
• QSFP28 form factor for high-density port deployments
• Four-lane parallel optics architecture at 25 Gbps per lane
• Supports up to 100 meters over OM4 multimode fiber and 70 meters over OM3 multimode fiber
• Single-unit packaging suitable for individual port upgrades or bulk deployments

Compatibility

Designed as an OEM-style QSFP28 transceiver for use in 100G-capable switches, routers, and network adapters equipped with QSFP28 ports that accept 100GBASE-SR4 modules.

Installation Notes

Installation should be performed by a qualified network technician. Power down or administratively disable the target port before inserting or removing the transceiver to avoid potential damage to the optical interface. Use a compatible MPO-12 connector and verify fiber type and cleanliness before seating the cable. Follow the equipment manufacturer guidelines and applicable data center cabling standards when deploying multimode fiber infrastructure.
