OM4 LC to LC Fiber Patch Cable 0.2m 4-pack - High Density 40/100G

Our review of the OM4 LC to LC 0.2m 4-pack finds this set aimed at network engineers and data center technicians who need short, reliable duplex patch leads for high-density connections. The biggest reason to buy is its combination of OM4 multimode performance and compact 0.2m length, which makes it ideal for linking transceivers and keeping racks tidy without excess slack. The cables are built with LSZH jackets, Japan-made zirconia ferrules and UPC polish to keep insertion and return loss low during frequent moves or dense patching.

Key Features

• Short 0.2m length: Prevents cable clutter and is perfect for cross-connecting adjacent ports in high-density patch panels.
• OM4 multimode performance: Supports 10G, 40G and 100G optics with a high bandwidth rating for reliable short-reach links.
• LSZH jacket: Offers safer installation in enclosed spaces and reduces smoke and toxic gas in the event of fire.
• Low insertion and return loss: UPC polish and zirconia ceramic ferrules deliver precise alignment for stable signal integrity.
• Clear A/B labeling: Embossed duplex clips and jacket tags make Tx/Rx identification and troubleshooting faster.
• Factory tested: Each cable is measured for insertion loss to meet quality control standards before shipping.

Who It's For

This pack is best for technicians working in data centers, SAN cabinets or comms rooms that use QSFP+, SFP+ or similar transceivers and need tidy, short patch leads for 10G/40G/100G connections. It is also suitable for premise installations where space is limited and frequent repatching occurs.

Those who need very long runs, singlemode links for long-haul applications, or armoured outdoor cabling should look elsewhere, since these are short multimode OM4 patch cables intended for indoor high-density use.

Pros & Cons

Pros

• High-density 0.2m length reduces bundle bulk and simplifies cable management.
• OM4 fiber and 2000 MHzkm bandwidth support modern 10G/40G/100G use cases.
• LSZH jacket and factory testing give confidence for installation in enclosed racks.
• Clear A/B marking and quality ferrules help lower insertion loss and speed troubleshooting.

Cons

• At 0.2m these are too short for setups that require any distance between devices or patch panels.
• Multimode OM4 is not suitable where singlemode, long-reach links are required.

Frequently Asked Questions

Will these cables work with 40G and 100G transceivers?
Yes. The OM4 multimode specification and stated distances support common 40G and 100G short-reach transceivers at 850nm within the listed ranges.

Are the jackets safe for indoor rack use?
Yes. The cables use LSZH jackets which reduce smoke and toxic gas emissions and are suitable for enclosed data center environments.

How is Tx and Rx identified on the duplex cable?
Each duplex clip and jacket tag is embossed with A/B and numbered rings to indicate Tx and Rx for fast installation and troubleshooting.
