LogiLink OS2 SC/SC Duplex Single-Mode Fiber Patch Cable, 3m, 9/125µm, LSZH, Yellow

For installations where signal purity cannot be compromised, this LogiLink OS2 patch cable stands apart from generic fiber jumpers by pairing ceramic ferrule SC connectors with a tightly buffered 9/125µm single-mode core. The duplex A-B polarity and LSZH jacket make it a dependable link for high-speed backbone connections, while the 3-meter length keeps server rooms and patch panels tidy without excess slack.

Highlights

• OS2 single-mode fiber with 9/125µm core/cladding for long-haul clarity
• Duplex SC to SC connectors with ceramic ferrules for repeatable mating
• Low insertion loss (< 0.3 dB) and high return loss (> 50 dB) preserve signal budget
• LSZH (Low Smoke Zero Halogen) yellow jacket for safety in enclosed spaces
• Supports Gigabit Ethernet, 10 Gigabit Ethernet, and Fibre Channel up to 10 km

In daily use

Terminating a backbone link or patching between switches and media converters, this cable’s crossed A-B polarity eliminates the need for crossover adapters. The 3-meter length is ideal for intra-rack connections, while the bend-insensitive design (minimum bend radius 7.5 mm dynamic) tolerates tight routing without micro-bending losses. Attenuation stays at 0.35 dB/km at 1310 nm and 0.25 dB/km at 1550 nm, ensuring headroom for future upgrades.
