1m SC/APC to SC/APC Single Mode Fiber Patch Cable, OS2 9/125 Duplex Corning, LSZH/OFNR, Yellow

The CableLeader FB114-96XX is an OS2 single mode duplex patch cable terminated with SC/APC connectors on both ends, identified by green housings. APC — angled physical contact — polishes each ferrule endface at an 8-degree angle, redirecting back-reflection into the cladding rather than straight back toward the source. The result is a minimum return loss of 65 dB, meaningfully higher than the 55 dB of a UPC connector, and the reason FTTH and GPON standards specify APC. Inside the yellow jacket run two Corning 9/125 um G657A1 fibers.

SC is the connector of the access network. Fiber wall plates, GPON splitter ports, and ONT uplinks overwhelmingly use the square-bodied push-pull SC format, whose keyed housing and 2.5 mm ferrule seat with a positive click that survives repeated household and field handling. With SC/APC on both ends, this cable patches outlet to ONT or splitter to panel directly, with no format change anywhere in the link.

Each connector uses a 31.8 mm boot and is factory-tested to 0.30 dB maximum insertion loss at 1310/1550 nm. The green housing is more than cosmetic: it is the standardized marker separating APC from blue UPC hardware, because the two polishes must never mate. Forcing an angled ferrule against a flat one damages both endfaces and produces high, permanent loss.

The jacket is LSZH/OFNR rated under UL file E510298. Low-smoke zero-halogen material limits toxic emissions in enclosed living spaces and equipment rooms, while the OFNR riser rating permits vertical runs between floors. The 2.0 mm x 4.1 mm duplex zipcord keeps each fiber in its own aramid-reinforced sub-unit, and RoHS compliance covers restricted-substance procurement requirements.

G657A1 bend insensitive glass tolerates the tight bends behind wall plates, inside ONT shelves, and around apartment cable routing without the attenuation spikes standard G652D fiber shows under the same handling, and it remains fully compatible with installed G652D plant. Typical deployments include the outlet-to-ONT patch in FTTH homes, splitter-to-panel links in MDU risers, and RF-over-glass video overlays.

Compatibility & Ordering Information — FB114-96XX mates only with SC/APC (green, angled) ports: fiber wall outlets, GPON splitters, ONT uplinks, and APC distribution panels. Never plug it into blue SC/UPC receptacles; the polish mismatch damages ferrules. The family is offered from 1 m through 3 m; select the variant covering the outlet-to-equipment distance plus a service loop. For a simplex single-fiber version see the FB121-96XX family; for SC/APC to LC/APC transitions see FB111-92XX; for links to blue LC/UPC equipment see FB113-92XX.

Product Comparison: SC/APC vs SC/UPC Single Mode Patch Cable

Both cables use the identical SC push-pull connector body over Corning OS2 9/125 G657A1 fiber; the difference is the endface polish, which sets back-reflection performance and which ports they may be plugged into. The table summarizes the decision:

Select the APC version (green, this product) for FTTH wall outlets, ONTs, GPON splitters, and RF video — the access-network standard.
Select the UPC version (blue) only when both ports are UPC data ports. APC and UPC are not interchangeable — mating them damages the angled ferrule and causes high loss.

FAQ

What is the difference between SC/APC and SC/UPC connectors?

The body is identical; the polish differs. SC/APC (green) has an 8-degree angled endface delivering 65 dB minimum return loss, while SC/UPC (blue) has a flat/domed endface at about 55 dB. FTTH and GPON standards specify APC because passive-optical and RF video signals are reflection-sensitive. The two are not interchangeable — mating them damages the ferrules.

Is this the right cable for my FTTH wall outlet and ONT?

Yes, if both ports are green SC/APC — the standard combination on fiber wall plates and ONT uplinks in FTTH homes. Push each connector straight in until it clicks. If one of your ports is a blue UPC or an LC format instead, use the matching CableLeader hybrid family rather than forcing a connector that does not fit.

What return loss does APC provide and why does it matter?

This cable is rated 65 dB minimum return loss, meaningfully higher than the 55 dB typical of UPC. Higher return loss means less light reflected back toward the source, which matters in GPON and RF-over-glass video where reflections degrade analog signal quality. The 8-degree angled endface is what achieves this performance.

How do I connect SC/APC connectors correctly?

Match green to green: SC/APC connectors mate only with APC (green) receptacles. Align the keyed housing, push straight in until it clicks, and pull the body — never the cable — to release. Avoid touching the angled ferrule endface, and leave a small service loop so the connection is never under tension.

Which fiber patch cable is best for FTTH internet service?

For the wall-outlet-to-ONT patch, choose this SC/APC to SC/APC cable — green angled connectors on both ends match standard FTTH plant. Choose an SC/APC to LC/APC cable (FB111 family) when the equipment side is LC/APC, or the LC/UPC hybrid (FB113 family) when it is a blue data port. The port format and color decide.
