25G SFP28 CWDM Transceiver

The Ficer Technology Co., Ltd module delivers 25 Gbps data transfer over single-mode fibre at the 1330nm CWDM wavelength. It targets network engineers upgrading 25GBASE-LR links or deploying CPRI option 10 and eCPRI 5G mobile fronthaul connections.

Thermals and Power Draw

Maximum power consumption is rated at 1.4 W from a single 3.3 V supply, keeping thermal load low inside dense switch chassis. The uncooled CWDM DFB laser operates across the commercial temperature range without active cooling, so fan noise remains unchanged in normal operation.

Coding and Diagnostics

Each unit is coded on request for Cisco, Juniper or other open switches, removing compatibility lock-outs at installation. A 2-wire interface compliant with SFF-8472 provides real-time diagnostic monitoring, while the hot-pluggable Duplex LC connector allows service without network downtime.

Questions about this item

How do I install this SFP28 transceiver and what step do people often miss?

Insert the module into an SFP28 port until it clicks, connect duplex LC single-mode fiber, and tell the supplier your switch brand and model so the correct coding is programmed before shipment.

What maintenance or replacement will this transceiver need over time?

The uncooled CWDM DFB laser and built-in CDR are sealed; no user-serviceable parts exist. Plan replacement only if link errors appear after years of 25.78 Gbps operation.

What limit appears first during sustained 25 Gbps use?

The 1.4 W maximum power draw and commercial temperature rating set the thermal ceiling; ensure the host switch provides adequate airflow for continuous 10 km links.
