Cisco 25GBASE-ER SFP28 Transceiver Module, Industrial Temperature, 1310 nm Single-Mode LC
SFP-25G-ER-I · Refurbished · 1 year warranty
Quantity (units)
Overview
Industrial temperature rating and a 40 km reach are the two features of the Cisco 25GBASE-ER SFP28 Transceiver Module, Industrial Temperature, part number SFP-25G-ER-I. It uses a duplex LC connector over single-mode fiber at 1310 nm, and it runs at 25GbE.
The reach note matters for planning: anything over 30 km is an engineered link. That means the loss budget, the fiber route and the connectors all need to be checked for the actual span, and the 40 km figure is not a guarantee for every route.
The industrial label identifies a module intended for environments outside standard indoor ranges, such as outdoor cabinets or unconditioned sites. Confirm the temperature limits with the manufacturer's documentation for your site.
The form factor is SFP28. Check that your switch or adapter accepts it, since hosts differ in which modules they allow.
The SFP-25G-ER-I is available new, refurbished and used. New and refurbished modules carry 1 year or 3 years of warranty, and used modules carry 90 days. Send your quantity, span length and host platform when you request pricing.
