Panduit FZ2ERLNLNSNM008 Opti-Core OM4 Duplex LC Fiber Patch Cord

The Panduit FZ2ERLNLNSNM008 is an 8-meter OM4 multimode fiber patch cord engineered for 10/40/100 Gigabit Ethernet backbones in enterprise data centers, telecom rooms, and high-density fiber distribution systems. Built on Panduit's Opti-Core platform, this duplex LC jumper uses laser-optimized 50μm OM4 fiber with aqua jacketing for instant OM4 identification on crowded patch panels. The 1.6 mm riser-rated (OFNR) cable meets NEC requirements for vertical runs between floors, eliminating the need for conduit in most commercial risers. Field techs rely on this cord to interconnect preterminated cassettes, cross-connect OM4 trunks, or provide device connections in MDA/HDA/EDA zones without the insertion-loss budget penalties that kill 40GBASE-SR4 and 100GBASE-SR10 links.

Key Features

• OM4 50μm laser-optimized multimode fiber — 400 m reach at 10G, 150 m at 40G, 100 m at 100G per IEEE 802.3
• Duplex LC connectors on both ends — industry-standard small-form-factor interface for switches, transceivers, and cassette modules
• Aqua jacket color — instant OM4 visual identification per TIA-598-D fiber color code, prevents cross-patching with OM3/OM2
• Riser-rated OFNR jacket — NEC Article 770 compliant for vertical cable runs in non-plenum spaces without conduit
• 1.6 mm tight-buffered cable — flexible bend radius for high-density patch panel routing, 10× package quantity
• Factory-terminated and tested — guaranteed insertion loss ≤0.3 dB typical, eliminates field termination labor and test equipment cost
• TIA-568-C.3 and ISO/IEC 11801 compliant — meets structured cabling standards for commercial premises OM4 channels

OM4 fiber uses a laser-optimized graded-index core profile that reduces differential mode delay to ≤3 ps/m, the bottleneck that limits 10GBASE-SR and faster protocols over older OM2/OM3 cable plants. This cord supports 10 Gb/s over the full 400-meter OM4 distance spec when paired with 850 nm VCSELs, double the 150 m limit of OM2. For 40GBASE-SR4 (four-lane 10G over MPO trunks broken out to LC duplex at the device), OM4 delivers 150 m versus 100 m for OM3 — the difference between reaching a remote row in a two-story data hall and falling short. The duplex LC physical-contact connectors use ceramic ferrules polished to <50 nm surface finish; return loss exceeds 20 dB to prevent back-reflection from degrading BER on sensitive coherent optics. Panduit's Opti-Core manufacturing includes automated end-face inspection and IL testing at 850/1300 nm, rejecting any jumper above 0.35 dB insertion loss.

Install this cord in telecom rooms where 10G uplinks aggregate access-layer switches, in enterprise data centers running VMware vSAN or Nutanix HCI clusters over 25G NICs with QSFP28-to-4×SFP28 breakout DACs, or in broadcast facilities patching 12G-SDI routers through OM4 cassette infrastructure. The 8-meter length suits cross-connects between facing racks (2-post telecom frames up to 12 ft apart) or ladder-rack overhead routing in row-based cooling layouts without excess cable service loops that waste pathway fill and trap heat. Riser rating allows you to run this jumper vertically through cable tray risers or J-hooks between IDF floors in multi-tenant office buildings — no need to transition to plenum-rated cord at every floor boundary the way you would with CM-rated horizontal cable. The aqua jacket is the TIA-598-D mandated color for OM4; it prevents accidental cross-patching to green OM3 or orange OM2 infrastructure, a mistake that downgrades your channel to the lowest common denominator and silently chokes 40G links to 10G fallback mode.

This patch cord ships in cartons of ten and meets TIA-604-3 (FOCIS-3) LC connector geometry, TIA-604-10 (FOCIS-10) ferrule endface standards, and ISO/IEC 11801 Edition 2.2 OM4 channel requirements. UPC number 07498392288. Panduit Opti-Core jumpers carry the manufacturer's standard warranty and are backwards-compatible with OM3/OM2 fiber links when you need a physical replacement cord but don't require the full OM4 distance advantage — the aqua jacket remains the only visual distinction when patching into older MMF infrastructure.
