What does LR mean on SFP?
Long Reach
SR stands for Short Reach, and LR stands for Long Reach.
What is the difference between SFP-10G-LR and SFP-10G-LR S?
SFP-10G-LR-S and SFP-10G-LR transceivers have different temperature ranges. But the operating temperature range of SFP-10G-LR-S is smaller, so SFP-10G-LR-S is better for shorter transmission distance applications than SFP-10G-LR.
What is the range of an LR SFP?
400m 10km
Comparison: SFP-10G-SR vs SFP-10G-LR vs SFP-10G-LRM
| SFP-10G-SR | SFP-10G-LR | |
|---|---|---|
| Wavelength | 850nm | 1310nm |
| Max. Distance | 300m/400m | 10km |
| Interface | LC duplex | LC duplex |
| Laser Type | VCSEL 850nm | DFB 1310nm |
What is LR and ER in SFP?
SR means short range, LR means long range, LRM means long reach multimode , ER means extened range and ZR means ze best range. Here is the details of these five types of 10g modules. SFP-10G-SR. SFP-10G-SR(Short Range) is a very common sfp module, which can links up to 300 meters in multimode fiber.
What is an LR optic?
LR means Long Reach, these transceivers support distance up to 10km over single-mode fiber and use 1310nm lasers. There is no minimum distance for LR, either, so it is suitable for short connections over single-mode fiber as well.
What is Cisco SFP 10G LR S?
Cisco SFP-10G-LR-S Compatible 10GBASE-LR SFP+ Transceiver Module (SMF, 1310nm, 10km, LC, DOM) Cisco SFP-10G-LR-S compatible SFP+ transceiver supports up to 10km link lengths over LC duplex SMF fiber. This transceiver is compliant with SFF-8431, SFF-8432 and IEEE 802.3ae standards.
What is the difference between single mode and multimode SFP?
Single mode SFP module has a narrower laser wavelength, which works mainly in 1310nm and 1550nm wavelength. Whereas multimode SFP module works in 850nm wavelength due to the larger core size.
What is difference between SFP 10G SR S and SFP 10G SR?
SFP-10G-SR-S optics only have COM (Commercial temperature range: 0~70℃). However, the temperature range of SFP-10G-SR can be EXT (Extended temperature range: -5~85℃), IND (Industrial temperature range: -40~85℃) and Storage temperature range (-40~85℃).
What is 10G SFP?
10G SFP+ transceiver is an enhanced version of the SFP transceiver that supports data rates up to 16 Gbit/s. It supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. SFP+ optical transceiver’s connector is duplex LC, and it operates on LC fiber patch cables.
