SFP-10G-SR vs SFP-10G-LR vs SFP-10G-LRM, What’s the Difference?

SFP-10G-SR, SFP-10G-LR, SFP-10G-LRM are commonly used in today’s data center connection. They are popular 10G SFP+ optical transceiver in terms of quantity used. They have similar specifications, thus some people sometimes is confused and difficult to find the right SFP+ transceiver for their switch. What is the difference? How to choose the right SFP+ transceiver? Here, we mainly focus on the three SFP+ transceivers, SFP-10G-LR vs SFP-10G-SR vs SFP-10G-LRM.

What are SFP-10G-SR?

Cisco SFP-10G-SR SFP+ transceiver is compliant with the 10GBASE-SR trendy. It’s miles warm-swappable input/output tool which permits a 10 Gigabit Ethernet port to hyperlink 300m in a fiber optic network. The SFP-10G-SR offers clients a huge sort of 10 Gigabit Ethernet connectivity options for statistics middle, company wiring closet, and carrier issuer delivery programs.

Due to the fact it is hot-swappable and MSA compliant, the Cisco SFP-10G-SR transceiver may be plugged immediately into any Cisco SFP+ based transceiver port, without the need to power down the switch. This functionality makes actions, add-ons, and exchanges short and painless. these modules also characteristic virtual Optical tracking (DOM) functionality which allows for tracking of the sign electricity, the temperature of the SFP, and the transceiver voltage.

The SFP-10G-SR 10GBase-SR module supports link lengths up to 300 meters on multimode fiber. The SFP-10G-SR requires at least OM3 fiber.

What is SFP-10G-LR?

SFP-10G-LR is generally standard for a Cisco 10GBASE-LR SFP+ module. SFP-10G-LR supports popular single-mode fiber with a link distance of 10 kilometers. The SFP-10G-LR is compliant with the 10GBase-LR trendy and supports up to 10 km of single mode fiber with a 1310 nm laser. LR additionally has no minimum distance, so it is also suitable for short distances on single mode fiber. This 10GBASE-LR SFP+ transceiver module transmits data at speeds of up to 10 gigabits per second, making it ideal for connectivity needs in large data centers, enterprise wiring closets, large campus and metro area networks.

What is SFP-10G-LRM?

SFP-10G-LRM is generally standard for a Cisco 10GBASE-LRM SFP+ module. The SFP-10G-LRM SFP+ module supports link lengths up to 220m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fibers (MMF). To ensure compliance with specifications through FDDI, OM1, and OM2 fiber, the transmitter should be coupled through a mode conditioning patch cable. For applications that over OM3 fiber or OM4 fiber, no mode conditioning patch cable is required.
