Pros & Cons
👍 Pros
- 20-meter length spans two-rack or inter-room runs without signal integrity penalties — OM3 fiber's 300-meter 10GbE ceiling means this cable operates with 93% headroom to spare.
- 50/125 µm OM3 core provides the modal bandwidth required for 10GbE VCSEL transmission, supporting the 850 nm wavelength used by virtually all SFP+ SR transceivers.
- OFNR-rated aqua jacket satisfies riser fire code compliance, eliminating the need to source a separately rated cable for vertical building installations.
- Complete electromagnetic immunity makes this cable suitable for routing alongside high-current power lines, motor drives, and other EMI sources that would corrupt copper Ethernet signals.
- LC/LC duplex termination is plug-compatible with the SFP+ ecosystem — no adapters, no media converters required.
👎 Cons
- Fixed 20-meter length cannot be field-shortened or extended — if your run is 22 meters, you need a different SKU, not a field modification.
- LC ferrules require careful handling; contamination from a single fingerprint on the end-face raises insertion loss and can degrade link reliability until professionally cleaned.
- OM3 multimode is incompatible with single-mode OS1/OS2 infrastructure — mixing fiber grades requires media converters and increases cost significantly.
- The aqua jacket provides no mechanical protection beyond basic abrasion resistance — this cable is not rated for outdoor, direct burial, or armored conduit applications.
Frequently Asked Questions
What is the maximum network speed this 20-meter cable supports?
This OM3 50/125 µm multimode cable is rated for 10 Gigabit Ethernet at distances up to 300 meters. At 20 meters, you're operating at 6.7% of that maximum reach — attenuation and modal dispersion are non-issues at this length.
How does 20 meters compare to the 15-meter variant for typical rack room installations?
The additional 5 meters matters when connecting equipment in non-adjacent racks or routing cable through overhead trays. The 20-meter length accommodates longer cabinet-to-cabinet runs and provides enough slack to re-route without purchasing a new cable if your rack layout changes.
Is the LC/LC connector format compatible with standard SFP+ ports?
Yes. LC duplex is the standard connector for SFP+ short-range (SR) multimode transceivers operating at 850 nm. Any 10GbE switch or NIC with an SFP+ cage and SR optics will accept this cable directly.
What does the OFNR jacket rating allow me to do during installation?
OFNR (Optical Fiber Non-conductive Riser) meets UL 1666 requirements for vertical cable runs through building floors and risers. It is appropriate for in-wall and in-riser installation where local fire code requires a rated jacket — though plenum-rated (OFNP) is required in air-handling ceiling spaces.
Can I use this cable for 40GbE or 100GbE connections?
Not with this LC/LC connector configuration. 40GBASE-SR4 and 100GBASE-SR10 require MPO/MTP multi-fiber connectors. This cable is purpose-built for 10GbE (and lower-speed) LC-connected applications.
