Fiber Optic Adapters and Components by Role in the Link

Adapters

Fiber Optic Adapters

Panel-mount adapters that align two connector ferrules across SC, LC, FC, ST, MPO and MTP interfaces.

Specify:

Interface, polish, sleeve material, key orientation and mounting style.

SC interface

SC Fiber Optic Adapters

2.5 mm ferrule with square push-pull body for ODF frames, ONU and OLT ports.

Specify:

Simplex or duplex, polish, flange style and sleeve material.

LC interface

LC Fiber Optic Adapters

1.25 mm ferrule in a compact housing for high-density panels and SFP or QSFP ports.

Specify:

Simplex or duplex, key orientation, polish and mounting flange.

FC interface

FC Fiber Optic Adapters

Threaded metal body for test gear, instruments and vibration-prone racks.

Verify:

Thread type, sleeve material, polish and panel cut-out.

ST interface

ST Fiber Optic Adapters

Bayonet-fit adapters for legacy frames, industrial panels and field devices.

Verify:

Bayonet key, sleeve material, panel mounting and loss.

MPO interface

MPO Fiber Optic Adapters

8, 12 and 24-fiber arrays with key-up or key-down orientation for parallel optics.

Verify:

Fiber count, polarity, keying, gender and loss.

MTP interface

MTP Fiber Optic Adapters

Refined multi-fiber housing that holds tighter alignment for lower insertion loss.

Verify:

Fiber count, polarity, keying, gender and loss.

Couplers

Fiber Optic Couplers

Alignment couplers for in-line joining, feed-through panels and test bench set-ups.

Verify:

Interface type, sleeve material, alignment tolerance and housing.

Flanges

Fiber Optic Flanges

Panel-mount adapters with mounting plates, screw holes or rectangular cut-outs.

Verify:

Cut-out size, screw spacing, plate material and panel thickness.

Hybrid

Hybrid Fiber Optic Adapters

Mixed interfaces such as SC to LC or FC to SC for migration and test-lead conversion.

Verify:

Both interface types, polish on each side, keying and loss.

Metal housing

Metal Fiber Optic Adapters

Machined housings for heat, vibration and repeated mating cycles.

Verify:

Housing material, thread or flange type, sleeve and temperature range.

Waterproof

Waterproof Fiber Optic Adapters

Sealed bodies with gaskets for outdoor cabinets, towers and drop entry points.

Verify:

IP rating, gasket material, sealing method and panel mounting.

Passive distribution

PLC Splitters
