Introduction of the Fiber Loss Budget Standard

2023-08-25 T&S News

1. About the standard

The IEEE 802.3ba standard and its newer version, IEEE 802.1bm, introduced 100G Ethernet into the data center space more than a decade ago. The next IEEE Ethernet standard, 802.3cd, defines a support speed of 50/100/200Gb. Shortly thereafter, 802.3b defined the speeds of 200Gb and 400Gb Ethernet. In 2018, Fibre Channel evolved from the 6th generation to the 7th generation, with duplex connections at 64Gbps and parallel connections at 256Gbps, and the need to support higher speeds has arrived.

Table 1 Ethernet and Fibre Channel link loss budgets at different speeds


2. Connector loss and supported transmission distance
Starting with 10Gb Ethernet and 8Gb Fibre Channel, the loss budget is already very small, with a total link loss of 2.6dB, of which 2.2dB is related to interconnection loss.


As we move into 256Gb of Fibre Channel and 400Gb of Ethernet spectrum, these losses will drop to 1.9dB and connector losses to 1.5dB to 1.0dB. Higher transmission rates mean that we are left with a very small margin for loss error. Insertion loss is a key performance parameter in the cabling measurement of data center. For the high-speed transmission needs of Ethernet and Fibre Channels, the transmission distance supported on multi-mode fiber has been narrowed to between 100 and 150 meters. Fiber connections inside most data centers don't go much further than that.


According to the TIA-568 standard, the transmission attenuation of 850nm over OM4 fiber is 3.5 dB/km. Based on the distance of the link, we can calculate the standard loss of 0.4dB. If the actual link length is shorter than the maximum standard, this distance loss can be further adjusted to provide more loss room within the link loss budget.

How to Define the Three Value Standards of the End Face of the Patchcord?

The two end faces of the fiber must be precisely butted so that the light energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. The successful connection of optical fiber lines depends on the quality of the physical connection of the optical fibers.

Introduction to Fiber Optic Connectors

The main function of the optical fiber connector is to quickly connect two optical fibers so that the optical signal can be continuous to form an optical path. Optical fiber connectors are movable and reusable, and they are also the most indispensable and most used passive components in optical communication systems.
