Fiber Optic Communication

Multimode fiber has been highly favored by Ethernet users and gained the widest acceptance in network backbones where it has offered users the opportunity to extend link distances, increase network reliability, and lower costs by centralizing electronics. OM3 fiber emerges just at the right time. The predominance of OM3 fiber is that utilizes laser-optimized fiber, which is the highest-capacity medium for short-wave 10G optical transmission. OM4 fiber just joined multimode fiber family after OM3 fiber in order to meet the requirement of longer range applications. This passage would give a brief introduction to OM3 and OM4 fiber, give a further analysis on their differences and selection guide, as well as list their applications. Introduction to OM3 & OM4 Fiber Both OM3 and OM4 fiber meet the ISO 11801 standard. The standard specifies that OM3 fibers are capable of 10 Gb/s performance over distances of up to 300m. Like being mentioned, the laser optimized 50/125 mm multimode O...

As a worldwide leader in IT and fiber optical networking, Cisco switches play a leading role in manufacturing network switches and in providing switching solutions for data center and enterprise networks with large and medium-size forms. MikroTik, a Latvian company which was founded in 1996 to develop routers and wireless ISP systems. Their cloud switches are highly favored by many Ethernet users in recent years. And thus, people are entangled with Cisco and Mikrotik switches. This article would give brief introduction to Cisco and Mikrotik switches, and put emphasis on Mikrotik Switches Vs Cisco Switches. Cisco Switches According to different usage, Cisco divided their switches into the following categories: LAN Access Switches, LAN Digital Building Switches, LAN Core and Distribution Switches, Data Center Switches, Service Provider Switches, Industrial Ethernet Switches , Virtual Networking and Small Business Switches. And every category has its switching series. The Cisco Ca...

25G Ethernet and 40G Ethernet are two “transiting” approaches for upgrading network from 10G to 100G. Some analysts believe 25G could be the second highest Ethernet server connectivity technology sold and shipped in the next five years, behind 10G. Meanwhile, a number of comments from industry experts declaring that 40G Ethernet is dead. Is that true? And how to make a right decision? This passage would give a brief introduction on 25G switch and 40G switch and put emphasis on 25G switch Vs. 40G switch. 25G Switch 25G technology is the new standard that offer significant density, cost and power benefits for server to top of rack connections. Its single higher speed 25 Gb/s lanes maximize bandwidth and switch fabric utilization. A single lane per physical port maximizes the number of connected servers or uplinks per switch. Generally, 25G switch is a 48 port switch on the 25G switch market right now. Nowadays, many major brands of switch manufactures have launched their 25G swit...
