50Meters 165ft FC/UPC to ST/UPC Multimode OM1 Fiber Cable - 10G Ready

In this review the 50Meters FC/UPC to ST/UPC Multimode OM1 fiber cable is evaluated for installers and network teams who need a reliable indoor jumper for 10G short-range connections. The bottom line: this orange, 3.0mm duplex patch cord delivers consistent optical performance and low insertion loss for gigabit and 10G networks, making it a sensible choice when a tested, factory-verified OM1 cable is required for data center patching or premise installations.

Key Features

• 50 meter length: Provides long reach for wiring closets and cross-connects without splicing or joins.
• FC to ST connectors: Dual-ended FC/UPC and ST/UPC terminations with Japan-made zirconia ferrules deliver precise alignment and stable mating.
• OM1 multimode fiber: Designed for gigabit and short-reach 10G SR and SFP+ transceiver connections commonly used in LAN and data center setups.
• Low insertion and high return loss: Factory-tested performance with approximately 0.3dB insertion loss and 30dB return loss to preserve signal integrity.
• Flexible 3.0mm jacket: Orange PVC jacket and a 3.0mm diameter allow easier routing through cable trays and panels while remaining flexible.
• Temperature-rated for indoor use: Operates from -20oC to +75oC and is better suited to indoor environments thanks to its soft PVC cover.

Who It's For

This cable is aimed at network technicians, small data center teams, and installers who need a tested OM1 duplex jumper for short-reach 10G and gigabit links, especially when connecting SFP+ or 10G SR transceivers to existing ST or FC ports. Its 50m length suits medium-distance runs inside buildings where an orange jacket helps with visual identification.

Those who need outdoor-rated, armored, or longer-span runs should look elsewhere; the PVC jacket and indoor temperature guidance mean this jumper is not optimized for harsh exterior environments or long outdoor trenches. If single-mode performance or APC polish is required, choose a different cable type.

Pros & Cons

Pros

• Consistent factory testing and measured insertion loss (~0.3dB) support reliable signal delivery.
• Japan-made zirconia ceramic ferrules and UPC polish produce low attenuation and stable mating.
• 3.0mm orange jacket and flexible construction make routing and identification straightforward in racks and panels.
• Suitable for 10G SR, 10G LRM, and SFP+ transceiver connections in local networks and data centers.

Cons

• Soft PVC jacket is intended for indoor use only and is not the best choice for outdoor or heavy-duty armored applications.
• OM1 multimode is a preferred legacy 10G option but has shorter reach than modern multimode grades for some 10G and beyond links.

Our Verdict

The 50Meters FC-ST OM1 jumper is a practical, factory-tested choice for indoor network runs that require reliable 10G SR and gigabit connections. Its measured insertion loss and quality ferrules offer dependable signal integrity, and the orange 3.0mm jacket makes installation and identification easier. It represents good value for teams needing an indoor multimode patch cord but is not intended for outdoor or armored use.
