Data Centre & Equipment Room Patch Cords
LC duplex OS2, OM3 and OM4 assemblies — tested, labelled and cut to the lengths your racks actually need.
Inside a data hall the enemy is not weather, it is handling. Cords are installed by people working quickly in confined spaces, then dressed, re-dressed and moved as the rack changes. A cord that is 30 cm too long becomes a coil in front of an airflow path; one that is too short puts a bend radius under stress. Both problems are solved at the specification stage, which is why we care more about your rack plan than about selling you the nearest stocked length.
What this environment demands
The problems that actually bite here
Density and cable dressing
Hundreds of cords in one rack leave little margin for error. The right length is a specification, not an afterthought — wrong lengths create coils that block airflow and make every future change harder.
Tray edges and cabinet doors
Cords are dragged across tray edges, pinched by ties and closed into cabinet doors. Repeated crush loads are a slow failure that often only shows up as a link error months later.
Polarity and duplex orientation
A duplex assembly has an A side and a B side, plus a clip orientation. Getting it wrong at the panel costs a call-out and a re-dress, so the assembly should arrive built the way your port plan expects.
Labelling that matches the rack
Incoming inspection and moves-adds-changes both depend on the label matching the port plan — not on someone opening every bag to work out what is inside.
Recommended configuration
The configuration we recommend for this environment
| Specification | Recommendation |
|---|---|
| Connector | LC duplex (most common); SC simplex or duplex |
| Polish | UPC for equipment ports; APC where the run belongs to a PON |
| Fiber mode | OM3/OM4 multimode for short in-hall links; OS2 single mode beyond ~300 m |
| Structure | Duplex with clip; armored where routing is exposed |
| Jacket | LSZH, 2.0 mm or 3.0 mm |
| Insertion loss | ≤0.3 dB per cord |
| Return loss | ≥50 dB (UPC) / ≥60 dB (APC) |
| Testing | 100% IL/RL measured; test report shipped with the order |
| Length | 0.5 m to 30 m typical, custom on request |
Send the rack or port plan and we will quote the assembly that fits it — no drawing is required for a patch cord, only the technical parameters.
Why buy from us
Five things that do not change between projects
Factory-direct supply
You order from the plant, not a trading desk. Our Jiangsu base produces roughly 20 million patch cords a year.
100% IL/RL tested
Every cord is measured for insertion and return loss before packing, with a test report per order.
7-day prototyping
New or custom builds are sampled in about seven days so your schedule is not held hostage.
Custom lengths
Made to order with a tolerance agreed in writing — not the nearest stocked length.
OEM packaging
Your label, your part number and your artwork, so the goods arrive ready for your warehouse.
FAQ
Four questions buyers ask us most
- Single mode or multimode for a data hall?
- As a rule of thumb: short high-speed links inside a hall are usually OM3 or OM4 multimode, while anything running beyond roughly 300 m — or leaving the building — is single mode OS2. If you tell us the distance and the equipment, we will confirm the mode rather than leave it to chance.
- Can you supply duplex assemblies with the polarity and clip we need?
- Yes. Duplex assemblies are built to the A/B orientation you specify, with or without the clip, and we can mark the ends so the orientation is obvious at the panel.
- Do you label and pack to our part numbers?
- Yes — OEM branding, your part number and your artwork. Cords are bagged individually with a specification label, so incoming inspection does not have to open every bag.
- What is the lead time?
- Pre-production samples are typically 3–7 working days and mass production 7–15 working days, depending on quantity and configuration. Dates are confirmed in the quotation.
