25G SFP28 Transceivers Product Detail
25G SFP28 ER is a SFP28 ER option using Duplex LC for 40km single-mode fiber links.
Use the published model direction and key parameters for selection and sample planning. Confirm compatibility coding, optional temperature grade, and production parameters in the formal specification or order document.
Specs & Features

25G SFP28 ER is designed for 40km links using Duplex LC. Selection must confirm the host form factor, electrical interface, PMD, FEC, fiber mapping, power and thermal limits, software version and the remote endpoint; the model name alone does not establish interoperability.
Selection FAQ
The complete loss budget and the dispersion penalty over the real route, not just the 40km label on 25G SFP28 ER. Long spans accumulate loss at every splice and patch point, and the achievable distance drops quickly once the fiber grade or route length differs from the plan.
Almost always. 25G SFP28 ER is engineered to overcome the attenuation of a 40km span, so on a short fiber the received power will sit well above the receiver overload point and the link becomes unstable. Confirm the overload figure in the ordering specification and attenuate before bench testing.
Give the host vendor, model and software version at both ends, the SFP28 port or lane mode, the operating temperature range, the quantity per site and the target delivery date. For 25G SFP28 ER also state the route length, fiber attenuation per kilometre and any existing amplifier or attenuator in the path. Compatibility is confirmed per platform, so the host details matter as much as the optical specification.
