Cisco is considered to be the leading networking company around the world, which designs, manufactures and sells networking equipment. Cisco’s products and services mainly focus on three market segments, namely, enterprise and service provider, small and midsize business. Cisco deals with various SFP+ modules that offer 10 Gigabit Ethernet connectivity options optimized for diverse networking environments such as data center, enterprise wiring closet and service provider applications as well. Cisco SFP+ transceivers consist of SFP-10G-SR, SFP-10G-LR (LRM), SFP-10G-ER and SFP-10G-ZR, etc. This article mainly introduces the SFP-10G- SR transceiver module.
Before talking about Cisco SFP-10G-SR, let’s have a look at the Cisco 10G SFP+ modules. Cisco SFP+ modules contain the following features and benefits: It supports 10GBASE Ethernet with the smallest 10G form factor. With hot-swappable input/output device, it can be plugged into an Ethernet SFP+ port of a Cisco switch (no need to power down when installing or replacing). Besides, its digital optical monitoring capability ensures strong diagnostic capability. And it also provides much more flexibility and convenience for interface choices.
As a member of the Cisco 10G SFP+ module family, the Cisco 10GBASE-SR (SFP-10G-SR) module supports a link length of 26 meters on standard fiber distributed data interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF (OM3), it is possible to reach up to 300m link lengths. While using 4700 MHz*km MMF (OM4), up to 400m link lengths are possible.
The SFP-10G-SR is a Class 1 laser product. It fully complies with the multi-sourcing agreement (MSA) which enables it to work in all MSA compliant platforms. The SFP-10G-SR must be operated within the specified temperature and voltage limits. The optical ports of the module shall be terminated with an optical connector or with a dust plug.
The Datasheet of Cisco SFP-10G-SR
The Cisco SFP-10G-SR transceiver is hot-swappable input/output device which allows a 10 Gigabit Ethernet port to link with a fiber optic network. Because it is hot-swappable and MSA compliant, the Cisco SFP-10G-SR transceiver can be plugged directly into any Cisco SFP+ based transceiver port, without the need to power down the host network system. This capability makes moves, add-ons and exchanges quick and painless. The datasheet of SFP-10G-SR is as follows:
|Part Number ||SFP-10G-SR|
|Data Rate ||10.3 Gbps|
|Power Supply Voltage ||3.3V|
|Operating Temperature||0~70 °C|
|Application||10 Gigabit Ethernet|
|Digital Optical Mon. (DOM)||Yes|
The Cisco SFP-10G-SR series also consists of two other modules: the Cisco SFP-10G-SR-S Module and the Cisco SFP-10G-SR-X Module. The Cisco SFP-10G-SR-S module supports a link length of 26 meters on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF (OM3), its link lengths can reach up to 300-meter. While using 4700 MHz*km MMF (OM4), up to 400 meter link lengths are possible. The datasheet of SFP-10G-SR-S is as follows:
|Part Number ||SFP-10G-SR-X|
|Form Type ||SFP+|
|Cable Type ||MMF|
|Extended Temperature Range||-5 to 85°C (23 to 185°F)|
|Max Data Rate ||11.0957Gbps|
|Max Cable Distance|| 300m over OM3 MMF|
|Optical Components|| VCSEL 850nm|
|Digital Optical Mon. (DOM)|| Yes|
|Receiver Sensitivity ||< -11.1dBm|
The SFP-10G-SR Optical Transceiver
’s energy efficiency, small size, hot-pluggable capabilities and excellent compatibility make it an ideal choice for setting up a new fiber optic network or upgrading an existing one.
