Use of Multimode (MM) Fiber Patch Cords Between Switches and OLTs
In high-speed data networks, Multimode (MM) fiber patch cords are widely used to connect fiber switches to OLTs or between network switches within the same rack or nearby cabinets.
These cables are ideal for short-distance, high-bandwidth transmission such as in data centers, control rooms, or equipment racks.
Why Use MM Fiber Cables?
Designed for short-range connections — typically up to a few hundred meters.
Works with SFP or QSFP modules operating at 850 nm wavelength.
Delivers excellent speed and reliability with lower installation cost.
Available Fiber Grades
OM2: Up to 1 Gbps – 10 Gbps, distance up to 82 m at 10G.
OM3: Optimized for 10G–40G up to 300 m.
OM4: Supports 10G–100G up to 400 m.
OM5: Extended for SWDM (Short-Wavelength Division Multiplexing) up to 150 m at 100G.
Typical Application Example
Between two fiber switches or between an OLT uplink and aggregation switch, D-TECH uses MM SFP transceivers at 850 nm and OM2–OM5 patch cords for efficient short-distance connectivity.
