## Summary description

Compatibility transceiver BlueOptics QSFP28 (78P4988-BO) for 100GBASE-SR4 links over multimode fiber. Uses MPO/MTP connector, four 850 nm lanes delivering up to 100 m reach. Supports digital diagnostic monitoring (DDM) and operates between 0°C and +70°C. Suitable for data center, switch-to-switch or high-speed server interconnects.

## Long description

BlueOptics QSFP28 Transceiver 78P4988-BO 100GBASE-SR4 MPO/MTP Multimode 4x850nm 100m DDM is a compatibility module designed for short-range 100 Gigabit Ethernet links over multimode fiber. The transceiver uses an MPO/MTP 12-fiber interface and transmits data across four parallel 850 nm lanes, supporting link distances up to 100 metres on suitable OM3/OM4 multimode fibre. It includes Digital Diagnostic Monitoring (DDM) functions and is specified for operation in ambient temperatures between 0°C and +70°C.
Advantages
This QSFP28 module provides a cost-effective, interoperable solution for 100GBASE-SR4 links where MPO/MTP connectivity is required. Its four-lane 850 nm optical design enables high aggregate bandwidth while keeping power consumption and heat generation appropriate for dense data centre environments. Integrated DDM support allows real-time monitoring of optical parameters such as temperature and optical power, assisting in fault detection and link management.
Suitable for
High-speed switch-to-switch connections inside data centres
Server-to-switch or server-to-server interconnects requiring 100 Gbps
Short-reach multimode fibre links using MPO/MTP trunk or harness cabling
Infrastructure upgrades where vendor-compatible QSFP28 modules are needed
When it may not be suitable
This module is intended for multimode fibre and short-reach applications; it is not suitable for single-mode fibre or long-distance links beyond the specified 100 m reach. It is also not a direct replacement for transceivers that require different signalling types (for example 100GBASE-LR4) or different connector styles than MPO/MTP.
Key specifications
Form factor: QSFP28 optical transceiver
Standard: 100GBASE-SR4
Connector: MPO/MTP multi-fibre interface
Wavelength: 4 × 850 nm lanes
Maximum reach: up to 100 metres on OM3/OM4 multimode fibre
Monitoring: Digital Diagnostic Monitoring (DDM)
Operating temperature range: 0°C to +70°C
How to use
Install the QSFP28 transceiver into a compatible QSFP28 slot on a switch, router, or host adapter, taking electrostatic discharge precautions. Connect an MPO/MTP multimode fibre cable or trunk to the transceiver, ensuring correct polarity and that the cable supports the target distance (OM3/OM4 for up to 100 m). Verify link status and diagnostic values via the host system or network management tools to confirm expected optical parameters and proper operation.
What to consider before purchase
Confirm the host device accepts third-party QSFP28 compatibility modules
Ensure your fibre cabling type (OM3/OM4) and MPO/MTP connectors match the required reach
Check that 100GBASE-SR4 and MPO/MTP connectivity meet your network design and polarity requirements
Verify ambient operating temperature and installation environment are within 0°C to +70°C
Usage recommendations
For reliable performance, pair this transceiver with MPO/MTP trunk cables certified for OM3 or OM4 multimode fibre, maintain clean connector endfaces using proper cleaning tools, and monitor DDM readings periodically to detect early signs of degradation.
