Transceiver BlueOptics QSFP28 BO25LS856S1D (980-9I90Z-00C000-BO) — 100GBASE-SWDM4, LC-Duplex, MMF, 850nm, 100m, DDM/DOM

The BlueOptics QSFP28 BO25LS856S1D is an optical transceiver module designed for short-reach 100GBASE-SWDM4 links over multimode fiber. It supports an LC-duplex interface and operates at an 850 nm wavelength to deliver up to 100 meters of connectivity in data center and aggregation environments. The module includes digital diagnostics (DDM/DOM) for real-time monitoring of optical parameters and is specified to function within a 0 °C to +70 °C operating range.

Advantages

This transceiver provides compact QSFP28 form-factor 100 G connectivity suitable for network equipment that requires vendor-compatible optics. Its support for SWDM4 over multimode fiber enables cost-effective short-reach high-bandwidth links while reducing the number of fiber strands compared with parallel multimode alternatives. Integrated digital diagnostics allow monitoring of transmit and receive power, temperature, and supply voltage to assist in maintenance and troubleshooting.

Suitable for

• Short-reach 100G uplinks in data center top-of-rack and spine-leaf architectures
• High-density aggregation switches and routers requiring LC-duplex multimode connections
• Replacing or upgrading existing multimode 100 G links with SWDM4-compatible modules

Key specifications

• Form factor: QSFP28 (100G)
• Standard: 100GBASE-SWDM4
• Connector: LC duplex
• Fiber type: Multimode fiber (MMF)
• Wavelength: 850 nm
• Maximum reach: 100 m
• Operating temperature range: 0 °C to +70 °C

How to use

Install the transceiver into a compatible QSFP28 port on a switch, router, or media converter following the host device manufacturer’s insertion and removal procedure. Connect LC-duplex multimode patch cables to the module ensuring correct polarity. Verify link status on the host device and use the digital diagnostics interface to check optical power, temperature, and voltage readings. Ensure the connected fiber infrastructure meets multimode standards for 850 nm SWDM4 operation.

Recommendations

Use this module for short-reach 100 G links within data center racks or between adjacent aggregation switches. Maintain clean connector endfaces, avoid tight bends in multimode patch cords, and monitor DDM/DOM parameters to detect gradual performance changes. Confirm compatibility with the network equipment vendor’s supported transceiver list before deployment.
