2m LC/APC to SC/UPC Simplex Single Mode Fiber Patch Cable, OS2 9/125 Corning, LSZH/OFNR, Yellow

The CableLeader FB117-92XX is an OS2 simplex hybrid patch cable that crosses both connector format and polish in one factory assembly: a green LC/APC connector on one end, a blue SC/UPC connector on the other, on one Corning single mode fiber in a single 2.0 mm jacket. It exists for the border where angle-polished APC plant meets flat-polished UPC equipment — a junction that otherwise requires two cables and a hybrid coupler — and is offered from 1 m through 10 m.

Orientation is fixed by the polish, not by signal direction. The green LC/APC end plugs into green APC ports — GPON OLT line cards, APC distribution panels, and reflection-sensitive analog equipment — where the 8-degree angled endface holds return loss at 65 dB minimum. The blue SC/UPC end plugs into blue UPC ports — legacy media converters, SC-port ONTs, and SC-port switches — at the 55 dB UPC standard. Never reverse the ends: an APC connector in a UPC port, or the reverse, leaves an air gap at the mismatched interface and can permanently damage both ferrules.

Simplex construction carries exactly one optical path, matching single-fiber PON drops, monitoring taps, and one-way signal runs. The LC/APC end uses a short boot 19.5 mm body with a 1.25 mm ferrule for dense panels; the SC/UPC end uses the push-pull 31.8 mm SC body that seats positively in wall plates and older equipment bays. Both terminations are factory-tested to 0.30 dB maximum insertion loss at 1310/1550 nm.

The jacket is LSZH/OFNR rated under UL file E510298. Low-smoke zero-halogen material limits toxic emissions in enclosed equipment rooms and residential installs, while the OFNR riser rating permits vertical runs between floors. The yellow jacket is the industry marker for single mode cable, keeping OS2 runs visually distinct from aqua and orange multimode patching, and RoHS compliance covers restricted-substance procurement requirements.

The Corning G657A1 fiber grade is bend insensitive, tolerating the tight routing radii found in wall enclosures, cable managers, and FTTH outlets without the attenuation spikes standard G652D fiber shows under the same handling. It remains fully compatible with installed G652D single mode plant, so the cable drops into existing OS2 structured cabling, splice trays, and panels.

Compatibility & Ordering Information — FB117-92XX joins green LC/APC ports (GPON OLT cards, APC distribution panels) to blue SC/UPC ports (legacy media converters, SC-port ONTs and switches) in one run. Match each end to its port color before patching. The family is offered from 1 m through 10 m; select the variant covering the run plus a service loop. For all-APC simplex jumps see FB115-91XX and FB116-92XX; for the hybrid pair running LC/UPC to SC/APC see FB120-92XX.

Product Comparison: Hybrid APC-UPC vs Same-Polish Patch Cable

Both constructions use the same Corning OS2 9/125 G657A1 simplex fiber; the difference is the polish at each end, which must match the two ports being joined. The table summarizes when each is correct:

Select this hybrid cable when one port is green APC and the other is blue UPC — it is the single-cable replacement for a coupler workaround.
Select a same-polish cable when both ports match: all-APC (see the LC/APC and SC/APC simplex families) or all-UPC. Always match connector color to port color before patching.

FAQ

What is the difference between a hybrid APC-UPC cable and a same-polish cable?

A hybrid cable carries a different polish on each end — here, green 8-degree APC on the LC end and blue flat UPC on the SC end — so it can directly join an APC port to a UPC port. A same-polish cable has identical endfaces on both ends and only links matching ports. You need the hybrid exactly when APC plant must reach UPC equipment.

Is this cable compatible with my media converter and APC panel?

Yes — if the media converter or ONT has a blue SC/UPC port and the panel or OLT side is green LC/APC, which is precisely the pairing this cable is built for. Check both port colors first: green means APC, blue means UPC. If both of your ports are the same color, use a same-polish cable instead.

What loss ratings does this cable carry?

Each end is factory-tested to 0.30 dB maximum insertion loss at 1310/1550 nm. Return loss differs by polish: 65 dB minimum at the green LC/APC end and 55 dB minimum at the blue SC/UPC end. The single Corning 9/125 um G657A1 strand is OS2 grade across the 1 m to 10 m family.

How do I install a hybrid LC/APC to SC/UPC cable correctly?

Match colors before anything else: green LC/APC end into the green APC port, blue SC/UPC end into the blue UPC port. Push the SC end straight in until it seats; align the LC latch with the keyway and press until it clicks. Never force a green connector into a blue port or the reverse — mismatched endfaces damage ferrules.

Which patch cable is best when my two ports have different polish?

A hybrid cable like this one is the correct choice — it terminates each end in the polish its port expects, keeping the APC side at 65 dB return loss and the UPC side at 55 dB. Adapting a same-polish cable through couplers adds loss and a failure point. Match the connector format and colors of your two ports, then pick the length.
