Features of O-band Amplifier

Optical fiber communication has become an integral part of modern communication networks. Several transmission bands, from the original O-band amplifier to the U / XL band, are defined and standardized in fiber optic communication systems.  Optical amplifiers are also used at other places in a network, such as within an optical switching node to compensate for switch fabric losses.

A Semiconductor O-band Amplifier is a laser diode (LD) with no feedback from its input and output ports and is also known as a Traveling-Wave Amplifier. Semiconductor Optical Amplifiers, or SOAs, have shown to be capable and multi-purpose devices that serve as critical building blocks for optical networks.

As a result, several functions have been achieved by adjusting the optical signal purely in the optical region. Here we have summarized some of the critical features of O- band amplifiers.

What is O-band Amplifier?

The O-band Amplifier is used fiber doped with rare earth metals as the amplification medium. The fibers are very similar to the erbium-doped fiber used for amplification in the C and L bands. O-band transmission over SMF results in higher light attenuation than C-band, primarily due to higher Rayleigh scattering.

Creating in-house O-band amplifier networks is a long-term goal for optical communication advancement. Simple optical fiber networks, such as polymer optical fiber, would effectively deliver network services in homes or offices. The method for transmitting radio signals over polymer optical fiber has already been devised and tested.

Features of O-band Amplifier

• A limited number of optical amplifiers for the O-band are already on the market. O-band transceivers have seen widespread application in high-speed Ethernet. The fundamental reason is that dispersion adjustment in the O-band is significantly easier than in the C-band. This is also offered in L bands.

• In the 2010s, O-band Amplifier was one of the fastest-growing Ethernet interfaces. The o-band optical amplifier used four wavelengths known as DWDM or LAN-WDM wavelengths, and each of the four wavelength lanes transmits a 25 signal to the high-speed transmission. Thus an O-band amplifier can achieve data transfer speeds of up to 100 Gbps.

• O-band amplifier components provide signal re-boosting and appropriate optical power to monitoring ports, and they are available for all kinds of signals and protocols. 

• With an O-band amplifier, transmission systems based on the 1310 nm wavelength domain can be utilized in tandem with current transmission systems based on the 1550 nm wavelength domain. This will allow for more efficient use of the existing fiber infrastructure.

• O-band amplifier is fully compatible with a simple network management protocol (SNMP), It is a unified network management platform that provides a common mechanism in network devices such as routers, servers, firewalls, etc.

A variety of optical amplifiers for the O-band are available in the market. This blog has put together all the important information about O-Band amplifiers and their key features. To know how O-band Optical Amplifier is useful in 100G Ethernet Network Monitoring, check our blog.
