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

The CableLeader FB118-91XX is an OS2 simplex hybrid patch cable that keeps one connector format and changes only the polish: a blue LC/UPC connector on one end, a green LC/APC connector on the other, on one Corning single mode fiber in a single 2.0 mm jacket. It is the direct bridge between flat-polished data equipment and angle-polished APC plant in all-LC installations, offered in a compact 1 m through 3 m family sized for in-rack and cross-panel patching.

Orientation is fixed by the polish. The blue LC/UPC end plugs into blue UPC ports — SFP transceivers, switches, media converters, and UPC patch panels — at the 55 dB minimum return loss standard for data links. The green LC/APC end plugs into green APC ports — APC distribution panels, GPON equipment, and reflection-sensitive analog gear — where the 8-degree angled endface holds return loss at 65 dB minimum. Never force an APC connector into a UPC port or the reverse: the mismatched endfaces leave an air gap and can permanently damage both ferrules.

Simplex construction carries exactly one optical path, the format for BiDi links, monitoring taps, and single-strand patching between panels. Both connectors use the short boot 19.5 mm LC body with a 1.25 mm ferrule, so the cable routes cleanly through high-density managers on both ends, and each termination is 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 — FB118-91XX joins blue LC/UPC ports (SFP transceivers, switches, media converters, UPC panels) to green LC/APC ports (APC distribution panels, GPON equipment). Match each end to its port color before patching. The family is offered from 1 m through 3 m for in-rack and cross-panel runs. For a two-fiber version of this polish pair see the FB112-91XX duplex family; for the hybrid jump toward SC/APC plant see FB120-92XX.

Product Comparison: Hybrid Simplex vs Hybrid Duplex LC/UPC to LC/APC

Both cables solve the same polish border — blue LC/UPC on one end, green LC/APC on the other, on Corning OS2 9/125 G657A1 fiber; the difference is the number of fibers, which must match how the link carries signal. The table summarizes the decision:

Select the simplex version (this product) when the link uses exactly one fiber across the polish border — BiDi optics or single-strand patching.
Select the duplex version when equipment transmits and receives on separate fibers. On both cables, always match the blue end to blue UPC ports and the green end to green APC ports.

FAQ

What is the difference between LC/UPC and LC/APC, and why one cable with both?

LC/UPC is blue with a flat/domed polish rated 55 dB minimum return loss; LC/APC is green with an 8-degree angled polish rated 65 dB. The two cannot mate directly — so this hybrid cable terminates one end in each polish, letting a UPC data port and an APC plant port share one link without couplers.

Is this cable compatible with my SFP transceiver and APC panel?

Yes — SFP transceivers and switch optics use blue LC/UPC ports, which take the blue end, while APC distribution panels and GPON equipment use green LC/APC ports, which take the green end. Confirm both port colors before ordering; if both ports are the same color, use a same-polish LC cable instead.

What loss ratings does this cable carry?

Each LC connector is factory-tested to 0.30 dB maximum insertion loss at 1310/1550 nm. Return loss follows the polish: 55 dB minimum at the blue LC/UPC end and 65 dB minimum at the green LC/APC end. The single Corning 9/125 um G657A1 strand is OS2 grade across the 1 m to 3 m family.

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

Match colors first: blue end into the blue UPC port, green end into the green APC port. Align each LC latch with its keyway and press until it clicks; press the latch to release. Never force a connector into a port of the other color — the mismatched endfaces damage both ferrules. Leave a small service loop at each end.

Which cable is best for linking a switch to APC plant — hybrid simplex or hybrid duplex?

Choose this hybrid simplex when the link runs on one fiber — BiDi optics, monitoring taps, or a single-strand panel jump. Choose the FB112-91XX hybrid duplex family when the equipment transmits and receives on separate fibers, the standard two-strand case. Count the fibers the two ports use; that decides.
