The classification methods of optical cables
Optical fiber cable is a communication line that uses optical fibers meeting optical performance requirements as the transmission medium to achieve optical signal transmission. It consists of components such as the cable core, reinforcement elements, and sheath, and may also include additional elements like waterproof layers, buffer layers, insulation layers, and armor layers as needed.
The classification methods of optical cables mainly include the following:
By transmission medium: categorized into single-mode fiber optic cables and multimode fiber optic cables.
According to the cable core structure: it is divided into stranded optical cable, skeletal optical cable, central tube optical cable, ribbon optical cable, and flat optical cable.
Reinforced components: categorized into non-metallic optical cables, standard optical cables, and reinforced component optical cables.
By installation method: divided into duct optical cable, overhead optical cable, direct-buried optical cable, and submarine optical cable.
Based on the usage environment, they are categorized into indoor optical cables and outdoor optical cables.
Applications
OM3 LC fiber jumpers with 50/125 micron core are engineered for short-reach 10 Gigabit Ethernet runs inside server rooms. The aqua-jacketed multimode duplex cable supports effective modal bandwidth of 2000 MHz·km at 850nm, enabling reliable rack-to-rack connectivity for hyperscale deployments.
This 10Gb-rated LC multimode patch cord delivers consistent throughput for Fibre Channel storage area networks. Network engineers selecting OM3 fiber patch cables for SAN infrastructure benefit from the 300-meter reach at 10GbE, reducing the need for signal regeneration in mid-sized facilities.
Facilities requiring multimode backbone cabling between floors rely on bend-insensitive LC-to-LC OM3 cables to navigate tight conduit pathways. The LSZH outer sheath meets fire safety codes for plenum and riser installations in commercial buildings.
Video production environments transmitting uncompressed 3G-SDI or 12G-SDI over fiber benefit from the low insertion loss of this duplex LC OM3 jumper. Broadcast engineers often bulk-order aqua multimode cables for patching between SDI routers and camera control units.
Healthcare IT teams deploying PACS systems and diagnostic imaging equipment choose OM3 LC duplex fiber for its EMI immunity and bandwidth headroom. The factory-tested optical performance of each cable ensures compliance with stringent hospital network uptime requirements.
FAQ
Q1: What transmission distance does an LC to LC OM3 multimode cable support at 10GbE?
A: The OM3 50/125 duplex fiber cable supports 10 Gigabit Ethernet up to 300 meters. For longer runs within the same building, consider upgrading to OM4 or singlemode fiber alternatives.
Q2: Can I use this aqua multimode patch cord with 40GbE QSFP+ transceivers?
A: Yes. When paired with 40GBASE-SR4 QSFP+ modules, the OM3 LC fiber jumper supports parallel transmission up to 100 meters. Ensure your breakout cable or MTP-to-LC harness matches the polarity configuration.
Q3: Is the LSZH jacket on this cable suitable for plenum spaces?
A: LSZH (Low Smoke Zero Halogen) cable jackets reduce toxic fume emission during combustion. For air-handling plenum installations governed by strict fire codes, confirm local regulations accept LSZH-rated OM3 multimode fiber patch cables.
Q4: How does the 10mm minimum bend radius protect my network?
A: The bend-insensitive G657A1 fiber core tolerates tighter routing without signal degradation. Installers working with high-density LC patch panels in confined server racks rely on this flexibility to maintain link integrity.
Q5: What is the typical insertion loss specification for this duplex LC OM3 cable?
A: Each connector end is tested to ≤0.3dB insertion loss. Lower loss translates to greater optical power budget, which is critical when cascading multiple patch points in a structured cabling system.
Q6: Are custom lengths available for bulk data center orders?
A: Yes. OEM fiber patch cord services include custom cable lengths, labeling, and packaging. Contact the sales team for wholesale multimode LC-to-LC cable pricing on orders exceeding 100 pieces.
Q7: What color code identifies OM3 multimode fiber?
A: Industry convention uses an aqua (light blue-green) jacket for OM3 50/125 fiber cables. This color coding helps technicians distinguish multimode links from yellow singlemode or orange OM1/OM2 cabling during installation.
Q8: Does this patch cable support 25GbE applications?
A: OM3 fiber is rated for 25GBASE-SR up to approximately 70 meters. For full 100-meter 25GbE reach, OM4 multimode duplex LC cables offer additional modal bandwidth margin.
