Three Popular 10GBASE-SR SFP+ Modules Introduction

Time has witnessed the history and development of optical transceivers over the years. As we can see, the modern transceiver modules are moving in the direction of hot-pluggable design, smaller size, lower cost, lower consumption and higher speed. To cater for the above needs, 10GBASE-SR SFP+ transceivers have been frequently used in data centers. So what’s the options for 10GBASE-SR SFP+ modules? This tutorial will introduce three popular types for you: E10GSFPSR, 455883 b21 and J9150A.

10GBASE-SR SFP+ Module

10GBASE-SR is a 10 Gigabit Ethernet port standard specified in IEEE 802.3 Clause 49 for multimode fiber. It adopts 850nm lasers, which have the advantages of low cost, low power consumption, small size, and high density. The letters “sr” refer to “short reach”, but the exact reach distance depends on the fiber types matched with transceivers. For instance, when used over OM1 fiber, the 10GBASE-SR has a maximum transmission length of 33 meters. However, nowadays 10GBASE-SR SFP+ is commonly connected with OM3 or OM4 fibers to reach up to respectively 300 or 400 meters. E10GSFPSR, 455883 b21 and J9150A are three popular 10GBASE-SR 300m SFP+ modules.

This table shows the detail information of the three popular 10GBASE-SR SFP+ modules.

455883 B21

455883 b21 stands for HPE Blade System c-class 10GBASE-SR SFP+ module, which supports the 10 Gigabit SR standard. 455883 b21 10GBASE-SR transceiver module is in SFP+ form-factor specially for HPE blade switches and severs. It has the feature of low power consumption, under 0.8W. “HPE” refers to the brand name of Hewlett Packard Enterprise, which is the original equipment manufacture (OEM). The well-known brand superiority attracts customers to buy their expensive SFP+. However, FS.COM is a third-party vendor who can provide the exact same specifications and functions as the original 455883 b21 while offering a cost-effective price.

J9150A is a SKU code compatible for HPE X132 10G SFP + LC SR transceiver module, which is consistent with the 10 Gigabit SR standard in SFP+ form-factor. It is typically applied to some HPE Aruba switch series rather than HPE blade servers. However, the high compatible option of J9150A allows it to be used on blade switches too. HPE J9150A compatible 10GBASE-SR SFP+ is a compatible transceiver module produced by FS.COM under strict quality system verification. Meanwhile, it is supported on a wide range of HPE equipment and commonly used in data and optical networks.

Then explained each one respectively. People choose what to use according to exact matched equipment and their personal requirements.

The Principle of Buying Fiber Optic Transceiver

In the actual purchase, the enterprise considered an important factor is the price, especially small and medium-sized enterprises and SOHO office. We believe that a few hundred dollars, sufficient to meet the general needs of enterprises, except for special industries, such as telecommunications, military. Of course, in addition to price, but also must consider the compatibility of the product with the surrounding environment in line with and the product itself, stability, reliability, otherwise the low price and then bought useless. In order to be able to pick a good fiber optic transceiver to purchase points listed below:

1. Take a look at itself whether to support full-duplex and half-duplex, because some chips on the market, only to use full-duplex environment, can not support half-duplex, if then switch to other brands (N-Way Switch) or HUB, using a half-duplex mode, will cause a serious colision and packet loos.

2. Take a look at the connection test whether it be done with other fiber optic connectors, fiber transceiver currently on the market is more and more, such as the mutual compatibility of different brands transceiver test did not do it in advance will also have packet loss, transmission time is too long, unsteadiness.

3. Take a look at whether it is to prevent the loos of safety devices, because many manufacturers in the production of fiber optic transceivers, in order to reduce costs, often using the data transfer mode register, the biggest drawback of this way, the data transfer will be unstable, resulting in the loss, and the best way is to use a buffer circuit design, safe to avoid data loss.

4. To see whether the product has to do temperature tests because fiber optic transceivers will produce high fever, coupled with its installation environment usually outdoors, so the temperature is too high (can not be greater than 50°C), fiber optic transceivers whether normal operation, the user is very important factor to consider! The maximum allowable working temperature is how much? Equipment for one to need long-term running this very worthy of our attention!

5. To see whether the product in accordance with IEEE802.3 standard? The fiber-optic transceivers, such as to comply with the IEEE802.3 standard, if you do not meet the standards, then certainly there is a compatibility problem.

6. Weigh the manufacturer’s service Imagine, if your equipment is broken, the factory a few days did not solve the problem, your loss is much ah? Therefore, in order to make the after-sales service timely early response, suggest that you select when the region with superb strong technical force, reputable professional company. Only rich experience in troubleshooting professional technical engineers, more advanced tools of detection failure!

7. The purchase carefully observe the appearance of the product, and the fiber module housing has old, whether shiny or has signs of wear. In today’s market, many vendors in order to reap huge profits, used in fiber optic transceiver, optical switches and other equipment used or old fiber module used fiber optic module, caused a great deal of hidden network transmission, such as: optical fiber the optical path of the module to be contaminated on the signal transmission must be affected by a decline in the quality of transmission. The transmission quality drops, on the reception sensitivity also cause reduced, can also cause data loss phenomenon. Plus the fiber module used in the service life will be compromised at any time parts failure.

Fiber Optic Transceiver Notes

Fiber optic transceivers have a variety of different classification, while most of the actual use note the distinction between the categories according to different fiber optic connectors: SC connector fiber optic transceivers and FC / ST connector fiber optic transceiver.

Connect different devices using fiber optic transceivers, must pay attention to the use of the port.

1. Fiber optic transceiver connection to 100BASE-TX devices (switches, hubs):

Verify that the maximum length of twisted pair does not exceed 100 meters;

To the fiber-optic transceiver connected to one end of the twisted pair RJ-45 port (Uplink port), the other end of the RJ-45 port 100BASE-TX set (switches, hubs) (general population).

2. Fiber optic transceiver connection to 100BASE-TX device (NIC):

Verify that the maximum length of twisted pair does not exceed 100 meters;

Connect one end of the twisted pair to fiber optic transceiver RJ-45 port (100BASE-TX port), and the other end to the RJ-45 port of the network card.

3. Fiber optic transceiver connected to 100BASE-FX:

Recognized that the fiber does not exceed the length of the distance range of the equipment can provide;

SC / ST connector 100BASE-FX fiber connect one end of the fiber optic transceivers SC / FC / ST connector, connect the other end equipment.

Also need to add a lot of users in the use of optical transceivers that: as long as the length of the optical fiber in the single-mode fiber or multimode fiber can support a maximum distance you can normally use. In fact, this is a wrong perception, this understanding is correct only when connected devices are full-duplex devices, when there are half-duplex devices, optical fiber transmission distance there is a certain limit.
