Panduit FHCXN-12-03U HD Flex MPO to 6x SC Duplex OM3 Fiber Cassette

The Panduit FHCXN-12-03U delivers high-density fiber breakout in a single-slot HD Flex cassette, converting one 12-fiber MPO trunk to six duplex SC connections. Built for 10GbE and 40GbE architectures, this OM3 multimode cassette supports universal polarity configurations—eliminating field re-termination when integrating with multi-vendor structured cabling or bidirectional parallel optics. Factory-terminated 50/125 µm fiber ensures consistent insertion loss performance, while the modular design fits Panduit's HD Flex enclosure system for rack-space-efficient fiber management in enterprise networks, data centers, and AV distribution.

Key Features

1x MPO-12 male to 6x duplex SC breakout in single-slot HD Flex cassette form factor

OM3 multimode fiber (50/125 µm) — supports 10GBASE-SR to 300 m, 40GBASE-SR4 to 100 m per IEEE 802.3

Universal polarity adapts to Method A, B, or C without field re-termination or adapter flips

Standard insertion loss ~0.5 dB per mated pair, return loss >-20 dB per TIA-568-C.3

Black polycarbonate housing with individually labeled SC ports for circuit mapping

Factory fusion-splice termination for core alignment consistency and long-term reliability

This cassette fits Panduit's HD Flex enclosure system, which achieves up to 144 fibers in 1U by stacking twelve single-slot cassettes—essential when you're designing ToR switch fabrics, AV-over-IP distribution frames, or surveillance uplink aggregation in constrained rack environments. The rear MPO-12 male interface accepts pre-terminated trunk cable from backbone cross-connects or patch panels; the front six duplex SC ports connect directly to 10G SFP+ transceivers in switches, media converters, or fiber-to-copper gateways. OM3's 50 µm core diameter supports 10 Gigabit Ethernet out to 300 meters—adequate for intra-building horizontal runs—and 40GBASE-SR4 to 100 meters when all twelve fibers carry parallel lanes. Cassette-based breakout means you install MPO trunks once during initial buildout, then swap cassettes as network speeds scale without replacing backbone infrastructure.

Universal polarity is the feature that saves hours during moves, adds, and changes. Traditional fixed-polarity cassettes force you to match a specific Method (usually B); if your switch module or existing plant expects a different configuration, you're adding MPO key-up/key-down adapters or re-terminating connectors in the field. The FHCXN-12-03U auto-adjusts: internal fiber routing adapts to the connected trunk's polarity, so the SC ports always deliver correct transmit-to-receive continuity without tech intervention. Installation in an HD Flex enclosure takes under a minute—slide into chassis rails, snap retention clips, dress the MPO trunk through rear cable management. Each SC port uses push-pull latching (more durable than LC's fragile tabs under repeated insertions) and is labeled with fiber position for mapping back to DCIM records or label sheets. Polycarbonate construction tolerates the thermal cycling of equipment rooms and the mechanical stress of emergency service calls.

Factory termination delivers typical 0.5 dB insertion loss per mated pair—tight enough to keep 10G links in spec even when cascading through multiple patch points or running near the 300 m distance limit. Fusion-splice-grade core alignment eliminates the variability of field-polished connectors. Ships as a single cassette, packed ten per carton for multi-rack deployments. Backed by Panduit's manufacturer warranty covering defects in materials and workmanship. This cassette is the right choice when you're building a new 10G/40G network with modular density requirements, retrofitting LC-based infrastructure to higher port counts, or standardizing on a single platform across sites to simplify sparing and reduce training overhead.
