FAQ for HYTOPTODEVICE  H3C SFP-XG-LR-SM1310  Compatible SFP+Transceivers

Q1: Can I use the SFP-10G-LR with Multimode Fiber (OM3/OM4)?A:No. The LR transceiver is designed for Single-Mode Fiber (9/125µm). While it may be possible to connect over short distances (e.g., 5 meters), it will suffer from significant signal loss and CRC check errors. Always use the OS2 SMF(yellow).

Q2:Is SFP-10G-LR hot-swappable?A:Yes. HYTOPTODEVICE fiber optical modules are hot-pluggable, hot Pluggable SFP+ MSA Compliant.you can plug or unplug the module while the switch is powered on without damaging the hardware.

Q3:The link is "Up" but I have high packet loss. Why? There could be many reasons, but these two are common: 1. Dirty connectors:  Even tiny dust can obstruct signal transmission. Please use a one-click fiber cleaner.2. Fiber optic cable bending: Ensure the fiber optic cable bending radius is not too small (avoid sharp 90-degree bends).

Q4:Why is my switch not recognizing the Module?A:There are many reasons, and each case needs to be analyzed individually. One reason is that the module itself is incompatible with the switch. Some brands, such as Cisco, Huawei, and HP, require that the module's EEPROM contain specific firmware code;  Another reason is that the switch port and the module are incompatible. Ensure that your port is an SFP+ (10G) port. A standard SFP (1G) port cannot run a 10GBase-LR module.

Q5:Can I connect an LR module to an SR module? A:No. LR and SR operate at different wavelengths (1310nm and 850nm) and use different types of optical fibers. They are not interoperable.

Q6: What is the Best price for SFP-10G-LR fiber optical module? A: Price is important, but not everything. More important than price are product quality and compatibility.As a core-material self-sufficient factory, HYTOPTODEVICE offer factory-direct pricing without middlemen. The best price depends on quantity and compatibility requirements.

Q7: How to install SFP-10G-LR module for 10G Ethernet? A:You can refer to the following steps:Power off the switch;Insert the module into the SFP+ slot firmly until it clicks into place;Connect the duplex LC single-mode fiber to the module port;Power on and check the link LED – green means the connection is successful.

Q8:How can I find the Reliable SFP-10G-LR transceiver for 10G Ethernet networks?A:Choose a factory-direct supplier like HYTOPTODEVICE for reliable, 100% tested SFP-10G-LR modules with self-sufficient core materials, broad compatibility, and fast delivery.

Q9: Is SFP-10G-LR compatible with Cisco/Juniper/Arista? A: Yes, HYTOPTODEVICE SFP-10G-LR modules are 100% compatible with Cisco, Juniper, Arista, and more – at HYTOPTODEVICE, we own hundreds of switches from all major brands and test every module on real equipment before shipping to guarantee flawless performance.

Q10: How can I find the SFP-10G-LR with fast shipping available?A:Choose HYTOPTODEVICE – as a core-material self-sufficient factory, we maintain massive stock of SFP-10G-LR modules and ship within 24 hours for most orders. Bulk orders ship in 3-5 days. No delays, no backorders.

Q11: ​What is the difference between 10gbase lr and 10gbase lw?A:While they use same 1310nm wavelength, transmit with SMF, The key difference between 10GBASE-LR and 10GBASE-LW is the networking environment and framing protocol. The date rate and Protocol of LR is 10.3125 Gbps and Ethernet framing. LW is 9.953 Gbps and SONET/SDH framing.they are designed for different networks.SR for LAN (Local Area Network),SW for WAN (Wide Area Network).

Q12:Is SFP-10G-LR-S single mode or multimode?A:SFP-10G-LR-S is a Single-Mode fiber (SMF) optical transceiver with 1310nm wavelength and transmission up to 10km.
