At present, there are different types of optical fiber transceivers on the market, mainly divided into rack-type optical transceivers, desktop optical transceivers and card-type optical transceivers. Many friends are not familiar with gigabit single-mode fiber optic transceivers, let alone what kind of fiber optic transceivers to buy. The following ZR Fiber will introduce to you: How to choose the most suitable fiber optic transceiver?
Single Mode Single Core Fiber Transceiver
Optical fiber transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called photoelectric converter in many places and is used in optical communication equipment. Wider and wider. Optical fiber transmission equipment such as telephone optical transceivers and optical fiber access equipment can realize the transmission between devices through optical transceivers.
Generally, optical transceivers are divided into single-mode and multi-mode, single-fiber and dual-fiber. The interface type is SC by default, and FC, LC, etc. can also be configured according to customer needs. The transmission distance is generally 25 kilometers, 40 kilometers, 60 kilometers, 80 kilometers. , 100 km, 120 km, etc.
1. Gigabit single-mode optical fiber transceivers and multi-mode optical transceivers
Single-mode means that the optical signal propagates through a single channel, while dual-mode or multi-mode is roughly the same, propagating through dual-channel or multi-channel. When the user chooses whether to transmit through single-mode or multi-mode, the primary determining factor is the distance that the user needs to transmit. Single-mode transmission has less attenuation, but the transmission speed is also slower, which is suitable for long-distance transmission. Generally, the distance is greater than 5 miles, and single-mode fiber is the best choice; multi-mode transmission has larger attenuation, but faster transmission speed, suitable for For short-distance transmission, generally less than 5 miles, multimode fiber is the best choice.
Two, single-fiber and dual-fiber optical transceivers
Single-fiber refers to a single-core optical fiber, which is transmitted on one core; dual-fiber refers to a dual-core optical fiber, which is transmitted on two cores, one receiving and one sending. Under normal circumstances, users use dual-fiber more, because dual-fiber has an advantage in terms of price. Single fiber is generally used when the optical cable is relatively tight. For example, if the 12-core optical fiber is double-core, it can only transmit 6 networks; if all 12-core fibers are single-fiber, 50% of the wiring can be saved.
3. Optical transceivers of FC, SC, LC
FC, SC, and LC are a type of pigtail interface, and SC is the most commonly used pigtail interface. When purchasing the interface of the optical transceiver, pay attention to whether the interface matches the pigtail interface provided by you. Of course, there are also many types of optical cables on the market, such as one end is FC and the other end is SC. LC uses more SFP optical modules.
The transmission distance of the optical transceiver depends on the user's actual application selection, and the corresponding optical transceiver can be selected as long as the transmission distance between the two devices is long.
When purchasing optical fiber transceivers, special attention should be paid to the application of the corresponding port. If the wrong optical transceiver is selected, it may cause the office, remote telephone optical transceiver or other equipment to not work normally or the pigtail interface cannot be connected.
Application scenarios of single-mode single-core optical fiber transceivers
Through today's introduction, I believe that everyone has an understanding of how to choose a suitable gigabit single-mode fiber optic transceiver. If you want to know more about ZR optical fiber series products, welcome customers to come to consult.
