Panduit FHC39N-08H-10U 4-Port OS2 LC to MPO-8 Cassette

Panduit FHC39N-08H-10U HD Flex™ OS2 Fiber Cassette

The Panduit FHC39N-08H-10U delivers 4-port LC duplex to MPO-8 male breakout in a compact HD Flex™ cassette, purpose-built for OS2 single-mode migration in live datacenter environments. IT teams inherit dense blade-server or SAN arrays deployed with duplex LC – this cassette converts those legacy connections to a single 8-fiber MPO trunk without re-terminating every drop. Standard insertion loss, universal polarity, and polycarbonate housing rated for 10.1" enclosure depth mean you can drop this into Panduit, Corning, or third-party chassis without surprises. When rack space costs more per RU than the optics, 4-to-1 consolidation is how you justify the next 10G or 40G spine upgrade without a forklift.

Key Features

• 4-port LC duplex to MPO-8 male conversion — consolidates eight single-mode fibers into one trunk connector
• OS2 single-mode rated for 9 µm fiber — supports 10G, 40G, and 100G over extended campus or metro distances
• Universal polarity compatibility — works with Method A, B, or C trunk cables without adapter manipulation
• Standard insertion loss spec — maintains link budget headroom for multi-hop aggregation or long-haul runs
• Polycarbonate housing with 10.1" installation depth — fits Panduit FAP, FMP, and competitive 1RU/2RU fiber enclosures
• Black cassette body — consistent with structured cabling color codes for single-mode infrastructure

Legacy datacenter builds deployed thousands of duplex LC connections to blade servers, storage arrays, and top-of-rack switches. When it's time to upgrade the spine to 40G or 100G, re-pulling every fiber pair is a three-week change window and a six-figure labor bill. The FHC39N-08H-10U cassette solves the problem by converting four duplex LC connections (eight fibers) into a single MPO-8 male trunk at the patch panel, letting you swap the backbone to high-density MPO trunks while preserving every existing LC drop to the equipment. Standard IL spec means you're not sacrificing 1-2 dB just to avoid a rip-and-replace – critical when your 10 km metro run is already sitting at -18 dBm received. Universal polarity support eliminates the Type-A-versus-Type-B trunk guessing game that turns routine adds into all-hands troubleshooting calls.

The polycarbonate housing ships in Panduit's modular HD Flex™ form factor, so it drops into FAP and FMP enclosures, Corning CCH housings, or any standards-compliant 1RU fiber panel with 10.1" depth clearance. Four duplex LC ports fan out from the front; the MPO-8 male connector lives on the cassette spine and mates to your backbone trunk when you slide the cassette home. Installation is tool-free after the enclosure is racked – no epoxy, no fusion splicing, no field polishing. Black housing follows TIA-598-C single-mode color convention, reducing the chance that a junior tech plugs a multimode cassette into your OS2 plant during a midnight emergency. Each cassette is individually bagged; the carton holds ten units for staging multi-floor or multi-building rollouts without mid-project reorders.

OS2 single-mode fiber at 9 µm core diameter pushes 10GBASE-LR to 10 km, 40GBASE-LR4 to 10 km, or 100GBASE-LR4 beyond 10 km with the right optics – the cassette itself is passive, so it scales with your transceiver choice. When your environment mixes 1G, 10G, and 40G uplinks in the same enclosure, universal polarity means you can order one SKU and let the trunk cable type (key-up versus key-down) dictate polarity instead of stocking Method A and Method B cassettes. Standard insertion loss keeps total channel loss below the IEEE 802.3 budget even after you've added bulkhead adapters, trunk jumpers, and equipment patch cords. Cassette-based architectures let you reserve half your enclosure for LC and half for MPO, then shift the ratio as your installed base evolves – no wasted panel real estate, no stranded dark fiber.

Panduit's HD Flex™ cassettes carry a limited lifetime warranty and are manufactured to TIA-568 and IEC 61754 standards for interoperability with third-party enclosures and trunk cables. The FHC39N-08H-10U is the single-mode OS2 variant; Panduit offers OM3 and OM4 multimode equivalents under different SKUs if your application is exclusively short-reach. When rack density, migration timelines, and link-budget discipline all matter, this cassette is how you avoid the duplex-to-MPO retrofit disaster that costs twice the hardware budget and three times the labor.
