Defining the CAB-L600-30-N-N=

The ​​CAB-L600-30-N-N=​​ is a ​​30-meter single-mode fiber optic cable​​ designed by Cisco for high-capacity, long-distance data transmission. Equipped with ​​LC/UPC connectors​​, it caters to networks requiring minimal signal attenuation, such as metro backbones, large-scale data centers, and enterprise campuses.

Core Technical Specifications

• ​​Fiber Type:​​ ​​OS2 single-mode​​, optimized for distances up to ​​80 kilometers​​ (50 miles) with supported transceivers
• ​​Connectors:​​ ​​LC/UPC (Ultra Physical Contact)​​ for low insertion loss (55dB)
• ​​Jacket:​​ ​​Riser-rated (OFNR)​​ for safe deployment in vertical runs between building floors
• ​​Wavelength Support:​​ ​​1310nm and 1550nm​​, compatible with 100G/400G coherent optics and DWDM systems

Key Applications

​​Where does the CAB-L600-30-N-N= excel?​​

• ​​Metro Ethernet links​​ between Cisco NCS 5500 routers and core switches
• ​​Inter-building connectivity​​ in university or corporate campuses
• ​​Data center disaster recovery setups​​ requiring redundant, high-throughput links

Addressing Critical User Questions

​​Q: Is this cable compatible with QSFP28 transceivers?​​
Yes. The ​​OS2 fiber core​​ works with QSFP28-100G-LR4 and QSFP-DD-400G-ZR modules, provided the total link loss stays within transceiver budgets.

​​Q: Can it be used in underground conduits?​​
Yes, but only with ​​protective innerducts​​. The OFNR jacket resists fire but isn’t armored; for direct burial, select an armored variant or add conduit.

Practical Perspective

The CAB-L600-30-N-N= is a ​​cornerstone for scalable network architectures​​. While its 80km reach may seem excessive for small setups, enterprises planning growth or redundancy will find it a cost-saver. In an age where data velocity dictates competitiveness, skimping on fiber quality to save pennies per meter is a strategic misstep—one that amplifies costs exponentially during upgrades.
