CBO QSFP28-100G-SR4 transceptor de fibra óptica 100G SR4, QSFP28, multimodo 100G SR4

The CBO QSFP28-100G-SR4 is a QSFP28 100G SR4 fiber optic transceiver engineered for short-reach multimode links in data center and enterprise networks. The module provides 100 Gbps aggregate bandwidth by using four parallel 25 G lanes over multimode fiber with SR4 parallel optics. Designed for standard QSFP28 ports, it enables dense 100G connectivity in switches, servers and optical patch panels while simplifying upgrades from 10/40G infrastructure.

Advantages

The transceiver offers compact QSFP28 form factor compatibility for high port density and low-power operation per lane. Using SR4 parallel optics ensures straightforward lane mapping and interoperability with existing multimode cabling systems when used with compatible MPO/MTP connections. The module supports hot-pluggable installation and standard electrical and optical interfaces, enabling rapid replacement and minimal downtime for maintenance or upgrades.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or server slot while the host device is powered according to the host manufacturer’s instructions. Connect the multimode MPO/MTP cable ensuring correct fiber polarity and lane mapping for SR4 operation. After insertion, verify link status and speed through the host device network management interface and monitor optical and electrical diagnostics if available. For removal, follow hot-swap procedures to avoid disrupting active links when supported by the host.
