Product Overview

LCm-STf is part of the hybrid adapter range built by Ever Expresslink Limited in Ningbo, China. It is built on the LC (Lucent Connector) interface. The adapter is supplied as LC male to ST female.

LC uses a 1.25 mm ferrule in an RJ-style latch body, giving roughly twice the port density of SC in the same panel width. The latch is small and breaks if the cord is pulled sideways out of a dense panel. Use a boot or a push-pull tab on panels packed to 48 ports and above.

On the other face it mates to ST (Straight Tip). ST mounts a 2.5 mm ferrule in a bayonet coupling that locks with a quarter turn against a spring.

Key Benefits

Supplied as LCm-STf, so the part you receive matches the designation you ordered against
One part bridges two standards instead of a purpose-built converter cord
Available as male-to-female and female-to-female combinations
Keeps a migration reversible, because nothing is cut
Compact enough to live permanently in a field test kit

Problems It Solves

Equipment ports and installed plant using different connector standards
Test sets that cannot reach the port they need to measure
Migration projects where old and new connector types have to coexist
Custom converter cords ordered for what is really a temporary connection

Application Scenarios

High-density ODF and patch panels
Bench testing a component with a connector the test set does not carry
Temporary cross-connects during a cutover window
Extending a cord's reach through a panel without a new assembly
Connecting an FC test set to an SC or LC patch field

Who It Is For

Maintenance crews carrying a universal patching kit
Field engineers testing across mixed connector estates
Contractors migrating legacy ST or FC plant to SC or LC
Data-center teams integrating acquired or inherited cabling

Manufacturing Process

Sleeve selection matched to the ferrule pair
Housing machining or molding per connector combination
Assembly and concentricity verification
Mating check against both parent connector standards
Capping and individual packing

Quality Control

Concentricity verified against both mating standards
Insertion loss measured with reference cords on both sides
Retention and mating force checks on samples
Visual inspection of both interfaces before capping
Combination and gender verified against the order line

Customization Options

Any mainstream connector pair on request
Male-to-female or female-to-female
Ceramic or bronze sleeve
Panel-mount or inline body
Kitted sets for field engineering bags

Compared With Other Options

SC	SC is more forgiving to handle; LC fits twice the ports per rack unit
MTRJ	MTRJ carries a duplex pair in one ferrule; LC keeps the two fibres separately serviceable

Use Guide

Handling LCm-STf

Before You Order

Confirm both connector types and their genders before ordering
Match fiber mode on both sides; a hybrid adapter does not convert core size
Clean both ferrules before mating, as with any adapter

In Service

Expect the loss of a normal mated pair, and budget for it in the link
Do not use a hybrid adapter to bridge UPC to APC
Cap unused sides when the adapter lives in a field kit

FAQ

Questions About LCm-STf

What do you need from us to quote LCm-STf?

The quantity, the destination and anything that has to match on your side: connector and polish at each end, fiber mode and core size, and length where the item is an assembly. If you are matching a part you already buy, send the sample and we will quote against it.

Can LCm-STf be supplied with a different connector interface?

Yes. LC (Lucent Connector) is what this designation carries, and the same family is stocked across the other mainstream connector standards. Tell us the port you have to mate with and we will confirm the equivalent part.

Can I mate UPC to APC through a hybrid adapter?

No. The end-face geometries do not touch correctly and both faces can be damaged. Cross polish types with a proper converter assembly, not an adapter.

Are these suitable for permanent installation?

Panel-mount versions are built for permanent use. Inline versions are more often used in test kits and during migrations, though nothing stops them staying in place if the enclosure supports them mechanically.

Does a hybrid adapter change the fiber mode?

No. It aligns two different connector housings onto one axis but does nothing to the fiber. Single-mode has to meet single-mode, and 50/125 has to meet 50/125, on both sides.
