Definition Of Fiber Patch Cords
Fiber patch cord, often called fiber patch cable, fiber jumper, or fiber patch lead, is a length of fiber cable that terminated with fiber optic connectors (LC, SC, MTRJ, ST and etc.) at each end. The connectors allow fiber optic patch cord to be rapidly connected to an optical switch or other telecommunications/computer device. Fiber jumper is a key player for indoor use, like in server rooms or in data centers. Featuring excellent reliability, superior adaptability, and improved security, fiber patch cord has ranked the best choice for applications where conventional copper cables fail to reach.
All Types Of Fiber Patch Cords
Fiber optic patch cords in the market now have various types. We mainly divide them into common fiber patch cord types and special patch cord types in this explanation.
Most Frequent Fiber Patch Cords
Based on different specifications and standards, the common fiber patch cords can be categorified from the perspective of fiber cable mode, transmission mode, jacket type, connector type, and polishing type.
- Fiber Cable Mode: Single Mode or Multimode
- Number of Fiber Strands: Simplex or Duplex
- Jacket Type: PVC or LSZH
- Connector Type: LC, SC, ST or Others
Choose The Best Fiber Patch Cords-NEXANS Series
- LANmark-OF Aggregation Assembly MTP/F-4XDLC
Performance
The MTP connector has a low loss performance. A typical value for the insertion loss for the low loss MTP-MTP connection is 0.125 dB. The limit value is 0.3 dB measured according to standard IEC 61300-3-45.
Consistent quality
- In order to produce high quality,
- reliable pre-terminated multi-fibre cables,
- there are a number of physical characteristics that must be addressed.
Therefore, all LANmark-OF Pre-Terms are fully terminated and tested in a quality assured factory environment. They are delivered with these test results.
Application
The assembly allows to aggregate 4X 10G channels from the front of a patch panel into 1x 40G port on a switch.
The female MTP-connector fits with the male MTP connector inside the 40G QSFP+ port of the switch.
2. LANmark-OF ENSPACE Patch Cord Duplex LC
Characteristics
- Patch cord cable is according to IEC 60794-2-50
- Maximum insertion loss according to IEC 61300-3-4: 0.25 dB
- Typical insertion loss: 0.125 dB
- GIGAliteFLEX bend insensitive fibre
- A label is added close to the uniboot connector for traceability of the measurement results
Guarantees
Nexans LANmark-OF optical fibre patch cords have been designed for indoor applications in support of high speed protocols
Design
Nexans LANmark-OF patch cords are delivered according to the “Cross-Over” wiring principle to improve field installation (A1-B2, B1-A2). This complies to the requirements of IEC 11801 and EN 50174-1:2009.
The polarity of the ENSPACE patch cord can be changed by opening the uniboot connector on one side and change the position of the 2 LC connectors. A black and yellow plastic square identify the fibre inside the patch cord. The patch cords are delivered with the black square on the left on side A and on the right on side B. This is required for cross-over or optical crossed patch cords. By changing the position of the black square on side A from the left to the right the patch cord becomes an optical straight patch cord. This straight patch cord can be used for some rare legacy applications that have a non-standard polarity.
