Ubiquiti UACC-OM-QSFP28-SR4 100G Multi-Mode Optical Module

High-Capacity Fibre Links Within the Building Connect compatible high-speed equipment across the rack or equipment room with the Ubiquiti 100G SR4 Multi-Mode Optical Module. The QSFP28 transceiver uses an MPO-12 Type B UPC connection and supports multi-mode fibre links up to 100 m with OM4. It provides an alternative to a fixed-length direct attach cable when the installation calls for a separate fibre path. Highlights Short-Reach Optical Connectivity QSFP28 module with published 40/100 Gbps data-rate support. Manufacturer-listed accessory for EAV-Fiber and EAV-XG-24-PoE. Plan the Fibre Path Up to 100 m on OM4 or 70 m on OM3 multi-mode fibre. MPO-12 Type B UPC connector; fibre cable is separate. A Defined Module Choice 850 nm transmit and receive wavelength. Single-unit pack; maximum power consumption 2.5 W. Key Features Give 100G Uplinks a Separate Fibre Path Use the module in a supported QSFP28 port when the connection is better served by structured multi-mode fibre than an integrated direct attach cable. Ubiquiti lists it as an accessory for both Enterprise Audio/Video switches. The complete link still depends on the host ports, selected speed and an appropriate transceiver at the other end. Match the Connector and Fibre Type The optical interface is MPO-12 Type B UPC, rather than duplex LC. Select a fibre assembly with the required connector, polarity and supported multi-mode fibre type. The module’s published reach is up to 100 m using OM4 or 70 m using OM3. A cable that merely reaches the far equipment is not enough if the connector or polarity differs. Choose the Module for the Application The manufacturer publishes 40 and 100 Gbps data-rate support and compatibility with QSFP28 and QSFP+ interfaces. Confirm the operating mode supported by the particular equipment at both ends. This is a short-reach SR4 multi-mode optic; it is a different choice from the LR4 single-mode module or a copper RJ45 adapter. Plan Both Ends Before Ordering This listing supplies a single transceiver. Fibre cable and the far-end optic are separate unless already present in the installation. Check both hosts, link distance and cable specification as one design so the parts form the intended connection. For short adjacent-rack links, a compatible direct attach cable may be a simpler alternative. Summary The Ubiquiti 100G SR4 module provides a clearly specified multi-mode optical link option for compatible high-speed ports. Its MPO-12 interface and defined OM3/OM4 reach help installers choose the right fibre path. Verify both endpoints and the cable assembly before selecting the module for a new or existing network. Frequently Asked Questions Which Fibre Cable Does It Use?ExpandCollapse It uses multi-mode fibre with an MPO-12 Type B UPC connection. Match the required connector and polarity at both ends. A duplex LC cable does not connect directly to this module. How Far Can the Link Run?ExpandCollapse The manufacturer specifies up to 100 m using OM4 and up to 70 m using OM3. Actual link operation also depends on the complete cable path and compatible equipment at both ends. Is This a Pair of Modules?ExpandCollapse No. The published pack is a single unit. Check whether you need another compatible optic at the far end; fibre cable is not included. Can I Use It with Either EAV Switch?ExpandCollapse Ubiquiti lists this SR4 module with both EAV-Fiber and EAV-XG-24-PoE. Use a supported QSFP28 port and confirm the intended port speed and far-end equipment. Can It Replace Any SFP+ or Single-Mode Module?ExpandCollapse No. Its QSFP28 form factor and MPO-12 multi-mode interface differ from SFP+ optics and LR4 single-mode modules. Choose the form factor, fibre type, connector and operating mode required by the equipment. Read more
