SFP28 Transceiver CBO 25G ESR for Alcatel‑Lucent BO27Q856S3D — 25Gb/s Fiber Optic Module

SFP28 Transceiver CBO 25G ESR for Alcatel‑Lucent BO27Q856S3D — 25Gb/s Fiber Optic Module is a single‑lane 25 Gigabit optical transceiver designed for extended reach fiber links. The module fits into SFP28 ports on compatible Alcatel‑Lucent networking equipment and provides a 25G serial optical interface for uplinks and point‑to‑point connections. It supports standard optical transmission over single‑mode fiber for deployments that require higher bandwidth between switches, servers, or aggregation devices.

Advantages

The module delivers 25Gb/s line rate in a compact SFP28 form factor, enabling higher port density while maintaining compatibility with SFP28 sockets. Extended reach optics provide reliable links over longer single‑mode fiber runs. The transceiver is hot‑pluggable and follows industry optical and electrical signal conventions for straightforward integration into existing network hardware. Low power consumption and stable signal integrity minimize operating costs and reduce thermal load in dense deployments.

Suitable for

• Data center uplinks between top‑of‑rack and aggregation switches
• Switch‑to‑switch 25G connections in campus or enterprise networks
• Server network interfaces requiring 25Gb/s optical links
• Network edge or aggregation points where extended reach single‑mode fiber is used

Key specifications

• Form factor: SFP28 single‑lane transceiver
• Nominal data rate: 25 Gigabits per second
• Optical reach: extended reach on single‑mode fiber
• Interface type: duplex optical (LC) compatible
• Operating mode: full duplex serial optical transmission
• Power consumption: low profile suitable for high‑density racks
• Hot‑pluggable design for live hardware changes

How to use

Insert the SFP28 transceiver into an SFP28 port on compatible Alcatel‑Lucent equipment until it seats and the latch engages. Connect duplex single‑mode fiber with LC connectors, observing correct transmit/receive pairing. Configure the connected devices for 25G optical operation according to the switch or host interface documentation. Monitor link status and optical parameters through the equipment management interface to confirm correct negotiation and signal levels.

Recommendations

Verify fiber type and cleanliness before insertion, and avoid bending fiber beyond recommended radius. Use appropriate ESD precautions when handling the module. For optimal performance, match optical reach and wavelength characteristics to the fiber plant and confirm firmware or compatibility notes for the specific Alcatel‑Lucent platform in use.
