Fiber Optic & Network Cabling Products

Optical Passive Components

Optical passive components are the workhorses of every fiber network — they split, combine, filter, monitor, and isolate optical signals without consuming power. Optiunik supplies a complete portfolio of passive devices manufactured in our own facility and verified one-by-one before shipping. Our catalog covers PLC splitters in 1×N and 2×N variants for PON and FTTH access deployments, fused biconical-tapered (FBT) couplers with custom split ratios for monitor and tap applications, and the full WDM family — CWDM in 1U rackmount / ABS module / LGX cassette / standalone device form factors, compact CCWDM modules for ultra-low-loss free-space-optic deployments, DWDM mux/demux on the 100 GHz and 200 GHz ITU grids, FWDM triplexers for 1310 / 1490 / 1550 nm combining, and polarization-maintaining (PM) devices for coherent and quantum-grade optical links. Every device is tested for insertion loss, return loss, polarization-dependent loss, and channel isolation per Telcordia GR-1209 and GR-1221, ships with the matching test report, and is available with OEM-coded labels and private-label packaging on request.

Optical Transceivers

Optiunik manufactures the full ladder of pluggable optical transceivers from 10G SFP+ to 800G OSFP, all programmed with original-vendor compatibility codes — Cisco IOS XE, Juniper, Arista EOS, NVIDIA / Mellanox, Brocade, Huawei, H3C, Extreme, and others — and verified on real switch hardware before shipping. Common reaches we stock include SR / SR4 multimode (50–300 m), LR / LR4 / DR4 / FR4 single-mode 1310 nm (2–10 km), ER / ZR long-haul (40–80 km), plus tunable DWDM, BiDi, and CWDM variants for metro and access networks. Modules are DDM / DOM-enabled with full digital diagnostics over I²C, and every unit ships with an Optiunik-branded test report capturing optical Tx/Rx power, extinction ratio, and BER. For 200G / 400G / 800G modules we offer PAM4 DR / FR / LR / ZR variants and OSFP / QSFP-DD form factors suitable for AI clusters, spine-leaf fabrics, and HPC interconnects. Custom firmware coding, breakout labels, and printed compatibility lists are provided per OEM request.

High-Speed Cables

For in-rack and end-of-row cabling, direct attach copper (DAC) and active optical cable (AOC) assemblies remove the need for separate transceivers and patch cords — lowering BOM cost, simplifying inventory, and trimming insertion loss. Optiunik supplies passive DAC twinax cables (10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 400G QSFP-DD) in 0.5–3 m standard lengths and custom lengths to 7 m; active DAC and AOC variants extend reach to 30 m / 100 m respectively. Connector ends and breakout configurations (e.g., 100G QSFP28-to-4× 25G SFP28, 400G QSFP-DD-to-4× 100G QSFP28, 800G OSFP-to-2× 400G) are fully supported. Every cable is electrically pre-tested for BER, eye-pattern compliance, and Tx/Rx power across the full link budget, and programmed with the customer's switch vendor coding. Bulk pull-test and bend-radius certification ship with each shipment on request.

Fiber Patch Cords

Fiber patch cords are the last meter of every optical link. Optiunik supplies the full range of duplex, simplex, breakout, and MTP/MPO trunk patch cords, with every connector hand-polished and inspected on a digital interferometer before assembly. Connector options include LC, SC, FC, ST, MU, and E2000 in UPC and APC polish; fiber grades cover OS1 / OS2 single-mode and OM1 / OM2 / OM3 / OM4 / OM5 multi-mode (color-coded jacket per TIA standard). MTP®/MPO trunk and breakout cables are available in 8 / 12 / 16 / 24-fiber variants with Type A / B / C polarity and pinned or unpinned ends. Custom lengths are produced in 1 m steps without minimum charges (most orders ship within 3 days). Jacket options include PVC, LSZH, OFNP / OFNR, and armored for outdoor / harsh-environment deployments. All cables ship with individual IL / RL test reports.

Network Patch Cords

Network patch cords from Optiunik cover the complete copper Ethernet stack — Cat5e (100 MHz), Cat6 (250 MHz), Cat6A (500 MHz), and Cat8 (2000 MHz) — in both shielded (S/FTP, F/UTP) and unshielded (U/UTP) constructions. All copper conductors are 100% bare copper (CCA strictly forbidden), gold-flashed 50µ" 8P8C plugs, and individually tested for continuity, wire-map, attenuation, NEXT, and return loss before packaging. Jacket choices include flexible PVC for office runs, LSZH for plenum and riser installs, and outdoor PE for direct-bury applications. Custom lengths from 0.3 m to 30 m ship in 0.5 m increments, and bulk colors (blue, gray, black, white, green, yellow, red, orange) are stocked for color-coded installations. Each cable carries a permanent factory ID for traceability back to test data.
