Hybrid Adapter

FCm-LCf (Ref 289) is part of the hybrid adapter range built by Ever Expresslink Limited in Ningbo, China. It is built on the FC (Ferrule Connector) interface. The adapter is supplied as FC male to LC female.

Product Overview

FC uses a 2.5 mm zirconia ceramic ferrule inside a threaded metal coupling nut, so the mated pair is locked mechanically rather than held by a spring latch. The screw coupling keeps end-face contact stable when the rack is vibrating or when technicians work on neighboring ports, which is why FC stayed the default on test sets, monitoring gear and older carrier equipment.

On the other face it mates to LC (Lucent Connector). 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.

Key Benefits

Supplied as FCm-LCf (Ref 289), so the part you receive matches the designation you ordered against
Keeps a migration reversible, because nothing is cut
Compact enough to live permanently in a field test kit
Wide combination matrix across FC, SC, LC, ST, MU, DIN and E2000
One part bridges two standards instead of a purpose-built converter cord

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

Single-mode monitoring taps
Phasing an ST multimode backbone into new LC equipment
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

Who It Is For

Data-center teams integrating acquired or inherited cabling
Laboratories and test benches with multiple equipment standards
Maintenance crews carrying a universal patching kit
Field engineers testing across mixed connector estates

Technical Features

FC (Ferrule Connector) interface
FC needs the alignment key to seat in the adapter slot before the nut is tightened. Cross-threading a keyed FC is the single most common cause of high loss on an FC link.
Metal or thermoplastic housing depending on the pair
Panel-mount and inline versions
Dust caps on both interfaces
Precision alignment sleeve sized for the smaller of the two ferrules

Materials

Zirconia ceramic or phosphor bronze alignment sleeve
Metal or thermoplastic housing
Stainless retention hardware
Thermoplastic dust caps

Values shown are those carried by the product designation. Dimensional and optical values for a specific order are confirmed on the quotation.

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 seats faster with a push-pull motion; FC holds up better where the cabinet vibrates or ports get bumped
ST	ST twists on with a bayonet in a quarter turn; FC's threaded nut takes longer but resists loosening

Use Guide

Handling FCm-LCf (Ref 289)

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 FCm-LCf (Ref 289)

What do you need from us to quote FCm-LCf (Ref 289)?

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 FCm-LCf (Ref 289) be supplied with a different connector interface?

Yes. FC (Ferrule 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.

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.

Which connector combinations can you supply?

We stock a wide matrix across FC, SC, LC, ST, MU, DIN and E2000, in both male-to-female and female-to-female forms. If your combination is not in the list, send us the two connector types and we will quote it.
