Juniper Networks JNP-SFP-25G-SR Compatible 25GBASE-ESR SFP28 Optical Transceiver Module (MMF, 850nm, 300m, LC, DOM)

The Juniper Networks JNP-SFP-25G-SR compatible SFP28 transceiver provides 25GBase-ESR throughput up to 300m over OM3 MMF (400m over OM4) using a wavelength of 850nm via a LC duplex connector. Besides, it offers interoperability, laying a foundation for the next-generation network upgrade. Each SFP28 transceiver module is individually tested in targeted switch, and is fully compliant with the SFP28 MSA, RoHS, SFF-8424, SFF-8431 and SFF-8432 standards.
Featuring low power consumption and high speed, this 25G transceiver is ideal for 25G Ethernet, Telecom, and Data Center.
Note: The FS P/N is changed from SFP28-25GESR-85 to SFP-25GESR-85, but the product is the same. Only the FS P/N has been changed.

Product Certifications & Compliance
Fully certified to meet strict international safety and quality standards for the industry. Go to the Compliance Center for specific certifications.
Please Note: Installing a third party transceiver does not void your network equipment warranty. Network equipment manufacturers all have guidelines stating that warranty support on their products will not be affected.
