1G to 100G optics, tested for compatibility and backed by warranty. Bulk pricing available.
Browse 17,683 products in Transceivers & Optics.
Transceiver selection comes down to three letters and a number: form factor (SFP = 1G, SFP+ = 10G, SFP28 = 25G, QSFP+ = 40G, QSFP28 = 100G), reach (SR = short range over multimode fiber, LR = 10km over single-mode, ER/ZR = extended), and vendor coding — switches frequently reject or warn on optics not coded for their brand. We supply optics coded for Cisco, Juniper, Arista, HPE/Aruba, and Dell platforms, plus DAC and AOC cables for short in-rack runs.
One of the largest optics inventories in our catalog means same-day shipping on common parts and aggressive bulk pricing for MSPs and integrators wiring whole racks. Every module is tested before dispatch.
Yes, when correctly coded for Cisco — our compatible optics are coded per platform and tested before shipping. Specify your switch model and we will supply the right coding.
SR (short range) runs over multimode fiber up to ~300m and is standard inside buildings; LR (long range) runs over single-mode fiber up to 10km for campus and metro links.
For runs under ~5 meters — typically switch-to-server in the same rack — a DAC (direct-attach copper) cable costs far less than a pair of optics plus fiber and works identically.
