The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 16 Gbit/s. Since SFP+ is mostly used for 10G, we usually call it 10G SFP. It is a popular industry format supported by many network component vendors. In terms of the SFP+ transceivers, there are various major brands, such as Cisco, HP, Juniper etc. In the current market, the Cisco’s SFP+ transceivers are very popular with the customers, especially the Cisco SFP-10G-SR and SFP-10G-LR. However, these original transceiver modules are really expensive. To save cost, we usually use 3rd-party transceiver modules instead of the original brand. In this text, two kinds of compatible SFP+ modules that can severally replace the Cisco SFP-10G-SR and SFP-10G-LR will be introduced. These two kinds of compatible modules are all from the Fiberstore, the leading manufacturer and supplier of optical transceiver modules in China.
SFP+ is the Most Popular 10G Transceiver Module
Since there are many different 10GbE physical layer standards, many interfaces consist of a standard socket into which different PHY modules may be plugged. On the market, the common 10G transceiver modules are XENPAK, XPAK, X2, XFP and SFP+. XENPAK was the first MSA for 10GbE and had the largest form factor. X2 and XPAK were later competing standards with smaller form factors. XFP came after X2 and XPAK and it is also smaller. The newest module standard is SFP+. In comparison to earlier XENPAK or XFP modules, SFP+ modules leave more circuitry to be implemented on the host board instead of inside the module. Now SFP+ has become the most popular socket on 10GbE systems.
Common 10GbE Standards for SFP+
10 Gigabit Ethernet is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Some common 10GbE standards for SFP+ are shown in the table below:
Two Kinds of Compatible Cisco SFP+ Transceivers from Fiberstore
For 3rd-party transceiver modules are much cheaper than the original brand (Cisco. HP, etc), they are become more and more popular in the market. As a result, suppliers to offer these effective modules are also become more than before. But in my opinion, the Fiberstore does the best among them. They provide all kinds of compatible transceivers, especially the SFP-10G85-3M-CO and SFP-10G31-10-CO, which can entirely replace the Cisco SFP-10G-SR and SFP-10G-LR.
The SFP-10G85-3M-CO series multi-mode transceiver is a SFP+ module for duplex optical data communications such as 10GBASE-SR and 10GBASE-SW. This transceiver offers the same function with Cisco SFP-10G-SR and is fully compatible with Cisco devices. It is a hot-swappable input/output device, which means no need to power down if installing or replacing. Its transmission distance can up to 300m with duplex LC multi-mode Fiber cable.
The SFP-10G31-10-CO single mode transceiver is a small form factor pluggable module for serial optical data communications such as IEEE802.3ae 10GBASE-LR/LW. This transceiver offers the same function with Cisco SFP-10G-LR and is fully compatible with Cisco devices. This module is designed for single mode fiber and operates at a nominal wavelength of 1310 nm. Its transmission distance can up to 10km with duplex LC single-mode fiber.
All these products offered by Fiberstore are tested in-house prior to shipping to ensure that they will arrive in perfect physical and working condition. Fiberstore can guarantee these 10G SFP+ transceivers to work in your system and all of their 10G SFP+ transceivers come with a lifetime advance replacement warranty. Now they have many SFP-10G85-3M-CO and SFP-10G31-10-CO transceiver modules in stock. Therefore, Same-Day Delivery is available.
