The way to Select SFP Module When Deploying the Community?
As will be seen from the desk above, these three kinds of 10G SFP+ optical modules have many similarities, however on the identical time there are variations in wavelength, fiber kind and transmission distance. So, how to decide on when deploying the community? When there are greater than two optical modules that may meet the wants, will it make an enormous distinction to decide on one in all them? The next will examine the SFP-10G-LRM optical module and the SFP-10G-SR optical module, in addition to with the SFP-10G-LRM optical module and the SFP-10G-LR optical module.
Comparability Between SFP-10G-LRM and SFP-10G-SR
Each SFP-10G-SR optical module and SFP-10G-LRM optical module assist multi-mode transmission. Amongst them, when the SFP-10G-SR optical module is used with OM3 optical fiber jumper, the utmost transmission distance is 300 meters; when used with OM4 optical fiber jumper, the transmission distance can attain 400 meters. When the SFP-10G-LRM optical module is used with OM3 and OM4 fiber optic patch cords, the utmost transmission distance is 200 meters. So how to decide on between the 2?
Typically, when the transmission distance is lower than 300 meters, it is suggested to decide on the SFP-10G-SR optical module. Nonetheless, if there are different particular necessities for transmission, equivalent to a transmission distance of 200 meters when the modal bandwidth is 500 MHz·km, it is suggested to decide on SFP-10G-LRM. optical module.
Moreover, is SFP-10G-SR appropriate with 1GB? The SFP-10G-SR optical module is just not sometimes backward appropriate with 1GB speeds, so it’s important to contemplate the precise wants of your community infrastructure.
Detailed Comparability
A extra detailed comparability of the 2 fashions is as follows:
| Mannequin | Wavelength（nm） | Fiber Sort | Core Diameter（μm） | Modal Bandwidth（MHz km) | Distance(m) |
| SFP-10G-SR/ | 850 | multi-mode | 62.5 | 160(FDDI) | 26 m |
| 62.5 | 200(OM1) | 33 m | |||
| 50.0 | 400 | 66 m | |||
| 50.0 | 500(OM2) | 82 m | |||
| 50.0 | 2000(OM3) | 300 m | |||
| 50.0 | 4700(OM4) | 400 m | |||
| SFP-10G-LRM | 1310 | multi-mode | 62.5 | 500 | 220 m |
| 50.0 | 400 | 100 m | |||
| 50.0 | 500 | 220 m |
Since many customers are nonetheless utilizing OM1 and OM2 optical fiber jumpers, the SFP-10G-SR optical module can solely transmit 33 meters when used with OM1/OM2 optical fiber jumpers. The SFP-10G-LRM optical module is used with OM1/OM2 optical fiber. When the jumper is used, it could possibly transmit as much as 220 meters, so the SFP-10G-LRM optical module has a wider utility vary than the SFP-10G-SR optical module.
It ought to be famous that as a way to make sure that the SFP-10G-LRM optical module passes the FDDI (Fiber Distributed Information Interface) degree, the OM1 and OM2 optical fibers meet the specs, and the transmitter (converts the output sign of the sensor right into a sign that may be acknowledged by the controller, or a converter that converts the non-electricity enter from the sensor into {an electrical} sign and amplifies it for distant measurement and management.) ought to be coupled by means of a mode conversion jumper (i.e., a multi-mode conversion fiber jumper), for OM3 or OM4 optical fiber.
The applying of jumpers doesn’t require mode adjustment jumpers. It is suggested to measure the optical energy earlier than inserting the optical fiber into the optical module. When the obtained optical energy is bigger than 0.5dBm, a 5dB optical fiber attenuator ought to be inserted on the transmitting finish of the optical module on each side of the hyperlink.
Moreover, what number of watts fiber optic modem use a day can influence the general vitality consumption, so it’s important to consider energy utilization when planning your community.
Comparability Between SFP-10G-LRM and SFP-10G-LR
The SFP-10G-LR optical module is appropriate for long-distance communications as much as 10 kilometers, equivalent to interconnecting every constructing in a big campus and the creation of a metropolitan space community (MAN).
Along with the multi-mode transmission talked about above, the SFP-10G-LRM optical module may assist single-mode transmission. Single-mode is not going to undergo from gentle saturation. The transmission distance of the SFP-10G-LRM optical module can attain 300 meters.
Subsequently, for transmission inside 300 meters, selecting the SFP-10G-LRM optical module is a extra economical and efficient resolution; for transmission between 300 meters and a pair of kilometers, the SFP-10G-LRM2 optical module It’s extra appropriate than SFP-10G-LR optical module as a result of the value of SFP-10G-LRM2 optical module is decrease throughout the identical transmission vary; for transmission of two~10 kilometers, SFP-10G-LR optical module is The one choice.
Word: The utmost transmission distance of the SFP-10G-LRM2 optical module on single-mode fiber is 2 kilometers, which is appropriate for short-distance LAN connections.
