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.

10G Connectivity – Comparing XFP With SFP+

Defined in 2002, XFP (10 Gigabit Small Form Factor Pluggable) is a hot-swappable and protocol-independent transceiver for 10G high-speed computer network and telecommunication links. Except for XFP, there are SFP and SFP+ transceivers available for 10G connectivity. These devices plug into a special port on a switch or other network device to convert to a copper or fiber interface. So what is the difference between them? The following passage will provide a satisfying solution to you.

What Is XFP?
XFP is 10 Gigabit transceiver operating at wavelengths of 850nm, 1310nm or 1550nm. This module combine transmitter and receiver functions in one compact, flexible, and cost-effective package. The physical dimensions of the XFP transceiver are slightly larger than the original small form-factor pluggable transceiver (SFP). XFP transceiver modules are available with a variety of transmitter and receiver types including the SR, LR, ER and ZR. The maximum working distance of XFP SR is 300 meters. 10GBASE-LR XFP transceivers have a wavelength of 1310nm and a transmission distance up to 10 km. For example, XFP-10G-L-OC192-SR1 covers a distance of 10km with LC connectors. XFP-10GLR-OC192SR is Cisco XFP 10GBASE-LR/-LW operating at wavelength of 1310nm over singlemode fiber with a links length of 10km. Both 10GBASE-ER XFP and 10GBASE-ZR XFP modules have a wavelength of 1550nm, and the maximum transmission distance of 40km and 80km, respectively.

What Is SFP/SFP+?
SFP is most often used for Fast Ethernet of Gigabit Ethernet applications and can support speed up to 4.25Gbps. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is specified by the SFP transceiver multi-source agreement. The standard SFP transceiver, SFP+ supports speeds of 10Gbps or higher over fiber. The SFP+ product family includes cages, connectors, and copper cable assemblies. It is also similar to the performance requirements of SFF-8431 and also supports 8G Fiber Channel and 10G Ethernet applications. Take 46C3447 as an example, it is 10GBASE-SR SFP+ that can support a distance of 300m over OM3 cable.

What’s the Difference Between XFP and SFP+?
First of all, both of them are 10G transceiver modules and can contact with other types of 10G modules. The primary difference between SFP+ and the slightly older XFP standard is that the SFP+ moves the chip for clock and data recovery into a line card on the host device. This makes SFP+ smaller than XFP, enabling greater port density. Because of the smaller volume, SFP+ transfer signal modulation function, serial/deserializer, the MAC, clock and data recovery (CDR) and electronic dispersion compensation (EDC) function from the module to the Lord on the card. In addition, SFP+ compared to XFP, is a more compact factor package. The cost of SFP+ is also less than that to the XFP, X2 and XENPAK. It can connect with the same type of XFP, X2 and XENPAK as well. Therefore, SFP+ is more popular than XFP for 10G network.

Summary
10G optical transceivers are designed for 10G or 10Gbit/s data transmission applications including 10 Gigabit Ethernet, 10Gbit/s Fibre Channel, Synchronous optical networking. After years of development, there has been various different form factors and optics types introduced including XENPAK, X2, XFP and SFP+. But up to now, SFP+ is the most commonly used 10G transceivers available on the market. Fiberstore provides a large selection of 10G transceivers with minimum price and high quality.
