Juniper 10-Gigabit Ethernet Optical Transceivers – EX-SFP-10GE-SR and XFP-10G-L-OC192-SR1

From the emergence of 10G Ethernet, 10G optical transceivers have been developed along the way to meet the increasing requirement for high performance. From the old XENPAK to X2, XFP, SFP+, optical transceiver becomes smaller, more affordable and less power hungry, which might be a good news for 10G deployment. But with so many options available on the market, it is difficult for users to select a matching transceiver for their given application and hardware.
In fact, as the first 10G optical transceiver, XENPAK gradually exits the stage. Few people today would choose to use XENPAK and X2 for 10G connectivity. At the same time, XFP and SFP+ are offered by many vendors with different specifications. Of which Juniper XFP and SFP+ win a large market share. Today’s post will go on to talk about Juniper XFP and SFP+ transceiver module.
SFP+ Transceiver
The enhanced small form-factor pluggable (SFP+) is an upgraded version of the former SFP. SFP+, compared with the XENPAK and X2, possesses more compact size with data rates up to 10 Gbit/s. And it can also support 8Gbps/10Gbps/16Gbps Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. The SFP+ product family includes cages, connectors, and copper cable assemblies. In addition, they have the ability to connect to a variety of different types of optical fiber and are highly flexible. That’s why they are so desirable to designers.
Juniper EX-SFP-10GE-SR
Take Juniper EX-SFP-10GE-SR as an example, this SFP+ transceiver module is designed for use with Juniper network equipment and is fully compatible with Juniper switch and routers. This Juniper EX-SFP-10GE-SR is 10GBASE-SR SFP+ that operates over a wavelength of 850nm. It combines quality with low cost and gives you an ideal alternative except for the high price transceivers. Here are some key features of the optical transceiver.
  • Functionally identical to Juniper Networks EX-SFP-10GE-SR
  • LC ports designed for use with multimode fiber
  • Includes Digital Optical Monitoring (DOM)
  • 850nm wavelength signaling
  • Supports up to 300 meters of cabling
XFP Transceiver
XFP transceiver is a hot-pluggable and protocol-independent 10 Gbit/s optical transceiver designed to help drive cost and power consumption out of 10 Gbit/s optical networking applications. This particular XFP specification was developed by the XFP Multi-Source Agreement Group. XFP transceivers are capable of operating at wavelengths of 850 nm, 1310 nm, and 1550 nm at a single wavelength or through the use of dense wavelength-division multiplexing techniques. There are a variety of transceiver types available, but the most popular ones include: SR (850 nm and can transmit up to 300 m), LR, ER, and ZR. LR is 1310 nm and can transmit distances up to 10 km.
Juniper XFP-10G-L-OC192-SR1
XFP-10G-L-OC192-SR1 is Juniper 10GBASE-LR XFP transceiver. It operates at a wavelength of 1310nm with a link length of up to 10km links. ER is characterized by 1550 nm and can transmit distances of 40 km. ZR can transmit distances up to 80 km. Designers prefer to use XFP packaging because it has a smaller footprint than other devices. And this XFP-10G-L-OC192-SR1 is fully compatible with all Juniper series switches and modules which support XFP transceivers. The following are some detailed information about this product.
