25G SFP28

25G SFP28

Browse LINK-PP compatible 25G SFP28 optics for server NICs, TOR switches, and 100G breakout fan-outs. This category groups MSA-aligned 25GBASE modules—SR, LR, ER, BiDi, and dual-rate 10/25G options—coded for Cisco, Arista, Juniper, NVIDIA/Mellanox, and other major platforms. Start from the parent optics hub when you still need 1G–10G, jump to 100G QSFP28 for uplink or breakout planning, or open a Cisco compatible PN when the OEM part number is already known. Match host SFP28 cage, fiber type, duplex vs simplex LC, and rated reach on each product page before ordering.

Frequently asked questions

01.Which 25G form factors does this category cover?
This store lists LINK-PP compatible 25G SFP28 optical (and related dual-rate) modules for 25 Gigabit Ethernet server and switch ports. Use the on-page filters to narrow by reach and type, or return to the parent optics hub when you still need 1G–10G rates.
02.How do I choose SR vs LR vs BiDi for 25G?
Match media and distance first: SR for short multimode (typically up to about 100 m on OM4 with duplex LC), LR for about 10 km duplex LC single-mode, and BiDi (BX) pairs for simplex LC single-mode links that reuse one fiber with opposite TX/RX wavelengths. Always order matching upstream/downstream BiDi mates and confirm wavelength direction on the PDP.
03.Will a 25G SFP28 work in a 10G SFP+ port—or the reverse?
Electrical and EEPROM behavior is host-dependent. Some platforms accept dual-rate 10/25G SKUs in either mode; many 10G-only cages will not run a 25G-only optic. Prefer a dual-rate listing when you need mixed 10G/25G support, and verify the switch or NIC datasheet for port speed licensing.
04.Are these 25G modules coded for Cisco, Arista, Juniper, and NVIDIA?
Yes—select the Compatible PN that matches your OEM platform. LINK-PP 25G modules follow MSA electrical/optical specs and are EEPROM-coded for the target brand. Browse the Cisco compatible hub (or Arista / Juniper / NVIDIA hubs) and open the PDP that lists your switch or NIC part number.
05.Do LINK-PP 25G optics support DOM?
Most optical 25G SKUs support digital optical monitoring (DOM/DDM) for temperature, voltage, and Tx/Rx power per the datasheet. Confirm DOM support, industrial vs commercial temperature range, and rated reach on the individual product page before you order.
