Single-ended termination
Connector to splice point
The connectorised end connects to a matching adapter; the unterminated end is prepared for fusion splicing. Match the pigtail fibre to the installed cable, protect the splice and organise the tail in the splice tray without strain.
Protect the splice
Use the specified splice protection and tray routing. Maintain the required bend radius and identify each fibre.
Inspect the connector
Inspect and clean the connector end face before connecting it to the panel adapter.
Applications

Link planning
Fibre transmission distance comparison
Compare fibre grades and optical interfaces from 1G to 100G. These are link-planning references; cable length alone does not determine supported reach.

|---|---|---|---|---|
| 1G | 1000BASE-SX | OM1 / OM2 / OM3 / OM4 | 850 nm | OM1: up to 275 m; OM2/OM3/OM4: up to 550 m |
| 1G | 1000BASE-LX/LH | MMF / OS2 | 1310 nm | MMF: up to 550 m with the required launch conditions; 10 km-rated LX/LH module: 10 km on OS2 |
| 10G | 10GBASE-SR | OM1 / OM2 / OM3 / OM4 | 850 nm | OM1: 33 m; OM2: 82 m; OM3: 300 m; OM4: 400 m |

| 10G | ZR long-reach optics | OS2 | 1550 nm | 80–100 km, depending on the selected module and link budget |
| 40G | BiDi | OM3 / OM4 / OM5 | Module-specific paired wavelengths | OM3: 100 m; OM4: 150 m; OM5: up to 200 m with a compatible module |
| 40G | 40GBASE-SR4 | OM3 / OM4 / OM5 | 850 nm | OM3: 100 m; OM4/OM5: 150 m |
| 40G | SWDM4 | OM3 / OM4 / OM5 | 850–940 nm | OM3: 240 m; OM4: 350 m; OM5: 440 m for the specified SWDM4 module |

| 100G | 100GBASE-SR4 | OM3 / OM4 / OM5 | 850 nm | OM3: 70 m; OM4/OM5: 100 m |

Use the exact transceiver specification, fibre bandwidth, connector loss and installation conditions to confirm the link. BiDi, SWDM4 and extended-reach results depend on the selected module. Parallel optics also require the correct fibre count and polarity.
Product view
Identify the connector
Match the connector format and polish to the port or adapter. LC uniboot is a duplex housing option; the exact configuration is selected with the cable.
Connector care
Clean the connector before mating
Contamination at either end face can affect the optical link. Use the cleaner size that matches the connector ferrule.
Use a 1.25 mm one-push cleaner for LC ferrules. Inspect the end face, clean it and inspect again before mating.
Use a 2.5 mm one-push cleaner for SC, ST and FC ferrules. Keep protective caps fitted until the connector is ready to use.
Duplex connection
LC uniboot polarity reversal
These procedures apply to the reversible connector designs shown. They do not apply to every simplex connector, fixed duplex housing or pigtail.
Polarity reversal of LC uniboot
For a reversible uniboot housing, release the cover, exchange the two fibre positions and close the housing. Verify the end-to-end A/B mapping before reconnecting.
Polarity reversal of flat clip LC uniboot
Use the method appropriate to the selected connector housing. Release the flat clip or cover without pulling the fibres, reverse the channel orientation and secure the housing.
Repositioning the removable clip
For the removable-clip design shown, rotate the connector body 180°, reposition the clip and check that it is fully seated.
Installation
Connect LC, SC, ST and FC interfaces
Check that the optical port is inactive before inspection. Align the mechanical key, use the correct coupling and avoid twisting or straining the fibre.
Align the connector key with the module keyway and insert until the latch engages. Press the latch to release; do not pull the cable.
Insert the clean LC connector in the correct orientation. Confirm the latch is engaged and maintain a relaxed cable route.
Align the key and push the SC housing straight into the port. Hold the connector housing when removing it.
Align the ST key before engaging the bayonet coupling. For FC, align the key and secure the threaded coupling without twisting the fibre.
Product questions
Frequently asked questions
What information is needed for an order?
Specify LC, SC, ST or FC, UPC or APC where available, fibre grade, buffer diameter, length, colour and quantity.
Does the cable determine the maximum transmission distance?
Supported reach depends on the transceiver interface, fibre bandwidth, installed-link loss and application. Use the comparison table for initial selection, then check the exact transceiver specification.
Can every LC connector reverse polarity?
No. The illustrated reversal methods apply to the reversible uniboot designs shown. A fixed duplex connector, simplex lead or pigtail may require a different method or may not support field reversal.
Can I request inspection information?
Include the selected configuration and required inspection records in your enquiry. The applicable test scope and document format are confirmed for that assembly.
