A Full Panel in One Set
Many rack-mount fiber enclosures hold 12 SC adapters per panel. This set fills one panel completely. You get the whole TIA-598 sequence from blue through aqua. Strand 1 lands on port 1, and strand 12 lands on port 12, which keeps documentation clean.
OM4 Reach and Speed
OM4 multimode fiber delivers 4,700 MHz·km of effective modal bandwidth at 850 nm. That supports 10GBASE-SR up to 400 meters, 40GBASE-SR4 up to 150 meters, and 100GBASE-SR4 up to 100 meters. Few in-building links ever need more.
Tight Buffer vs. Semi-Tight
This version uses a fully tight 900 µm buffer bonded to the coated fiber. It's stiffer and more protective than semi-tight, which makes it a strong choice where fibers see repeated handling or route along sharp panel edges. The tradeoff is stripping in shorter increments of about 1.5 to 2 cm.
Connector Construction
Each SC connector uses a 2.5 mm ceramic ferrule in a square snap-in housing. It conforms to the TIA FOCIS-3 and IEC 61754-4 interface standards. The UPC polish keeps a flat, slightly domed contact for low insertion loss.
A Simple Loss Budget Check
Add up the expected losses before you install. Count each mated connector pair at up to 0.75 dB and each fusion splice at up to 0.3 dB, the TIA-568 maximums. Then add 3.5 dB/km of fiber at 850 nm. Compare the total to your transceiver's budget, and real-world numbers will usually come in lower.
