Jump to:

1. Data Center Interconnect

As hyperscale and colocation data centers transition from 100G/200G to 400G and 800G architectures, traditional copper cabling hits fundamental bandwidth-distance ceilings. High-density fiber panels demand ultra-low insertion loss and precise polarity management across hundreds of ports in limited rack space. Without a structured fiber approach, cable congestion, signal degradation, and prolonged commissioning timelines erode operational efficiency.

Product Category	Recommended Models	Key Advantage
MPO/MTP Multi-Fiber Patch Cords	OM4/OM5 MPO-12 / MPO-24 Trunk Cables	High-density 400G/800G parallel optic interconnect; typical insertion loss <0.35 dB per mated pair
DWDM MUX/DEMUX	AAWG 40CH / 48CH 100 GHz DWDM Modules	Passive wavelength multiplexing; doubles fiber capacity without additional dark fiber deployment
LC/SC Single-Mode Patch Cords	OS2 LC/UPC–LC/UPC; SC/APC–SC/APC Bend-Insensitive	G.657.A2 bend-insensitive fiber tolerates tight rack routing and high-density patching fields
Armored Breakout / Fan-out Assemblies	MPO–LC/SC Fan-out Cables; Ø2.0 mm / Ø3.0 mm options	Extra mechanical protection in raised-floor and overhead cable-tray environments
Fiber Patch Panels & Enclosures	1U / 2U / 4U Sliding-Tray LGX-Compatible Enclosures	Up to 144 LC duplex ports per 1U; integrated bend-radius guides and front-access cable management

Expected benefit: Deploy 400G-ready fiber infrastructure with validated polarity and <0.35 dB end-to-end channel loss, reducing commissioning time by up to 40% versus unstructured cabling.

2. 5G Fronthaul & Mobile Backhaul

5G fronthaul links between BBU/DU pools and remote radio units require deterministic sub-millisecond latency, high channel counts over limited fiber pairs, and the ability to withstand temperature swings from -40°C to +70°C. Conventional indoor-grade transceivers and patch cords fail prematurely under direct sunlight, condensation, and mechanical vibration at tower-top and pole-mount sites.

Product Category	Recommended Models	Key Advantage
CWDM/DWDM Transceiver Modules	CWDM SFP/SFP+ 10G/25G; DWDM SFP+ 10G Tunable	Industrial-temperature range (-40°C to +85°C); up to 18 CWDM channels on a single fiber pair
AAWG Multiplexer	AAWG 40CH / 48CH 100 GHz; Thermal-Stabilized (AAWG-T)	Colorless, directionless multiplexing with ±0.05 nm thermal drift for outdoor cabinet deployment
Outdoor Armored Fiber Cable	GYTA / GYFTY Single-Mode Armored; GYFTA53 Double-Jacket	Crush-resistant up to 3,000 N/100 mm; rodent-proof steel tape armor; UV-stabilized PE jacket
Industrial-Grade Optical Switch	1×2 / 1×4 / 2×2 MEMS Optical Switch; Latching Type	Sub-10 ms switching for protection-path rerouting; no continuous power required in latching mode

Expected benefit: Build a hardened fronthaul network that sustains carrier-grade availability across outdoor temperature extremes while consolidating 18+ wavelengths onto a single fiber pair.

3. FTTH Last Mile

Fiber-to-the-home deployments face intense cost-per-subscriber pressure, with installation labor often accounting for 60–70% of total rollout cost. Field splicing is slow and error-prone; pre-connectorized solutions that combine reliable optical splitting with tool-less field assembly can slash per-premises installation time while maintaining <0.3 dB connector loss budget.

Product Category	Recommended Models	Key Advantage
PLC Splitter	1×2 to 1×64 PLC Splitter; Bare-Fiber / LGX / ABS Box Types	Uniform splitting ratio; <0.3 dB insertion loss deviation across all output ports at 1,260–1,650 nm
FTTH Drop Cable	GJXFH / GJXH Bow-Type Drop Cable; 1-Core / 2-Core G.657.A2	Self-supporting design with steel messenger wire; UV-resistant LSZH jacket rated for direct-burial and aerial installation
SC/APC Fast Connector	SC/APC Pre-Polished Field-Assembly Connector; SM & MM Options	Tool-less assembly in under 60 seconds per connector; <0.3 dB typical insertion loss with index-matching gel
FTTH Termination Box	Wall-Mount / Pole-Mount FTTH Box; 1–4 Ports with Integrated Splice Tray	IP55-rated weatherproof enclosure; integrated bend-radius control for drop cable routing

Expected benefit: Reduce per-subscriber installation time to under 30 minutes with pre-connectorized drop assemblies, enabling service providers to scale from pilot to volume deployment without proportional OPEX growth.

4. Enterprise LAN & Campus Network

Enterprise campus networks face a multi-generational migration challenge: legacy OM3 backbone cabling cannot sustain 100G/400G over the distances required between buildings, yet a rip-and-replace approach is rarely budget-feasible. IT teams require a structured migration path that allows phased OM3→OM4→OM5 upgrades while maintaining backward compatibility with existing active equipment and minimizing operational downtime.

Product Category	Recommended Models	Key Advantage
OM4/OM5 Multi-Mode Patch Cords	OM4 LC–LC Duplex; OM5 LC–LC Duplex; OM5 MPO-12 Trunk	OM5 supports SWDM4 wavelengths (850–953 nm); 100G up to 150 m, 400G up to 100 m on existing duplex infrastructure
MPO–LC Breakout / Harness Cables	MPO-12(F) to 6×LC Duplex; MPO-24(F) to 12×LC Duplex	Seamless transition from parallel 40G/100G-SR4 ports to duplex 10G/25G switch interfaces
Indoor Distribution Cable	GJFJV / GJFJH Tight-Buffer Indoor Riser Cable; 2–24 Cores	OFNR/OFNP flame-rated jacket; color-coded tight-buffered fibers for quick field identification
Fiber Distribution Frame (ODF)	Wall-Mount ODF 12/24 Ports; Floor-Mount ODF 48/96 Ports	Front-access splice and patch zones within a single chassis; SC duplex or LC quad adapters

Expected benefit: Execute a phased campus fiber upgrade that leverages existing OM3/OM4 building trunks while adding OM5 capacity on bottleneck links—achieving 400G-ready inter-building backbone without full infrastructure replacement.

5. Smart City & IoT Infrastructure

Smart-city fiber networks span diverse topologies—traffic intersections, surveillance poles, environmental sensor clusters, and public Wi-Fi access points—often with aerial spans exceeding 100 meters between support structures. Cables must resist wind-induced vibration fatigue, rodent damage in underground ducts, and UV degradation over a 20+ year service life, all while maintaining a small bending radius for pole-mounted splice closures.

Product Category	Recommended Models	Key Advantage
ADSS (All-Dielectric Self-Supporting) Cable	ADSS 2–144 Cores; Span Lengths up to 200 m / 400 m / 600 m	Zero metallic components—immune to lightning and power-line induction; installed without messenger wire
Figure-8 Self-Supporting Cable	GYTC8S Integrated Figure-8 Cable; Steel Messenger + Single-Mode Fiber	Single-pass aerial installation; integrated messenger eliminates separate strand stringing; 2,500 N rated tensile strength
Armored Patch Cord	LC/SC Armored Single-Mode Patch Cord; Stainless Steel Interlocking Armor	Crush-resistant up to 500 N/cm; maintains <0.3 dB IL after 1,000 mating cycles for pole-top equipment connections
Outdoor Splice Closure	Dome-Type / Inline-Type Splice Closure; IP68 Rated; 12–96 Splice Capacity	Gel-sealed cable ports accommodate 3–8 drop cables (Ø5–20 mm); tool-less re-entry for maintenance access

Expected benefit: Deploy a 20-year outdoor fiber plant with all-dielectric aerial spans, IP68-rated splice protection, and armored last-meter connections that withstand corrosion, vibration, and temperature cycling without signal degradation.

6. Submarine & Long-Haul Transmission

Terrestrial long-haul and submarine cable systems span hundreds to thousands of kilometers, where every 0.01 dB/km of excess attenuation compounds into a system-level penalty measured in decibels. Standard outdoor cables lack the hydrogen-aging resistance, longitudinal water-blocking, and crush-armor layering required for direct-buried duct routes, river crossings, and shallow-water submarine segments.

Product Category	Recommended Models	Key Advantage
Ultra-Low-Attenuation Outdoor Cable	GYTA53 Double-Jacket Double-Armor; GYFTY53 Non-Metallic Armored	G.652.D / G.654.E fiber with ≤0.19 dB/km at 1,550 nm; dual steel-tape armor + longitudinal water-swellable tape
DWDM Long-Haul Transceivers	DWDM SFP+ 10G/25G 80 km; DWDM XFP 10G 120 km; Coherent CFP2 100G/200G	Dispersion-tolerant coherent detection for 2,000+ km unregenerated reach; tunable across full C-band 96-channel grid
Optical Amplifier (EDFA)	C-Band EDFA Booster / In-Line / Pre-Amplifier; Gain-Flattened 17–24 dBm Output	Flat gain ±0.5 dB across 1,529–1,562 nm; integrated OSC channel for remote management and span-loss monitoring
Custom Armored Strengthening	Single-Armor / Double-Armor Steel Wire; Submarine PE Outer Sheath; Hydrogen-Scavenging Gel	Engineered per trench depth and seabed terrain; anti-corrosion galvanized steel wires with bitumen compound flooding

Expected benefit: Commission long-haul links with ≤0.19 dB/km fiber attenuation and DWDM amplifier chains supporting 2,000+ km unregenerated reach—delivering carrier-grade availability for inter-city, cross-border, and submarine cable systems.
