• Juniper QFX Series Data Center Switches: Optimized for high-performance top-of-rack or spine/leaf fabrics using the QFX5100, QFX5110, and QFX5120 Series platforms.

• Juniper MX Series 3D Universal Edge Routers: Compatible with 10GbE SFP+ MIC/MPC line cards on the MX240, MX480, and MX960 routers.

• Juniper SRX Series Services Gateways: Fully compatible with security platforms equipped with 10GbE SFP+ ports, such as the SRX300, SRX1500, and SRX4000 series.

Main Application Scenarios of SFP 10G ER

• Long-Span Campus Aggregation: Links distribution layer edge switches to core switching fabric across large corporate or university campuses where building distances exceed standard 10km limits.

• Metropolitan Area Networks (MAN): Connects geographically dispersed company sites, municipal offices, or remote facilities directly into the primary network infrastructure.

• Disaster Recovery Backup Paths: Drives low-latency, high-bandwidth storage replication and data syncing between an enterprise data center and a remote backup facility up to 40km away.

  Technical Warning: When testing or deploying this 40km single mode fiber module over short distances (typically less than 20km), an optical attenuator (6dB to 9dB) must be used. Failure to attenuate the signal may cause permanent damage to the receiver due to optical overload.

FAQ FOR 10G 1550NM SFP+Transceiver Module
Q1: What is the maximum transmission distance of HYTOPTODEVICE Juniper EX-SFP-10GE-ER40? 
A1: Tested to reach up to 40km over standard single-mode fiber. Equipped with stable 1550nm laser, the transceiver effectively offsets fiber attenuation to realize certified long-distance transmission.
 
Q2: What is the difference between Juniper EX-SFP-10GE-LR and HYTOPTODEVICE EX-SFP-10GE-ER40?
A2: Core differences lie in working wavelength and supported transmission range:
- EX-SFP-10GE-LR: 1310nm wavelength, maximum 10km transmission;
- HYTOPTODEVICE EX-SFP-10GE-ER40: high-power 1550nm laser, engineered for long-haul links up to 40km.
 
Q3: Do I need an optical attenuator for short-distance testing of HYTOPTODEVICE EX-SFP-10GE-ER40?
A3: Yes. A 5dB~10dB inline optical attenuator is required when deployed on fiber shorter than 15km. Its high-output laser carries excessive optical power; direct connection with short patch cables without attenuation may permanently damage the built-in receiver photodiode.
 
Q4: How does HYTOPTODEVICE ensure full compatibility with Juniper switches?
A4: Every production batch gets real-machine verification on physical Juniper hardware running native Junos OS instead of virtual emulation. Our modules can be correctly identified via system CLI, and we supply test videos upon client request to prove stable compatibility.
 
Q5: What fiber patch cable matches HYTOPTODEVICE EX-SFP-10GE-ER40?
A5: Duplex LC-to-LC single-mode fiber cord is required. OS2 9/125µm single-mode cable is highly recommended to lower insertion loss and secure reliable full 40km link performance.
 
Q6: Can HYTOPTODEVICE EX-SFP-10GE-ER40 work at 1Gbps speed?
A6: No. It is fixed-rate 10Gbps SFP+ without rate downshift or 1G auto-negotiation. Select purpose-built 1G SFP modules if you need 40km long-haul 1G networking.
 
Q7: What latch color stands for Juniper 10GBASE-ER SFP+ module?
A7: Per global MSA rules, 10GBASE-ER adopts red bale clasp latch. Our EX-SFP-10GE-ER40 uses standard red latch for fast field identification as 1550nm extended-range optics.
 
Q8: Can HYTOPTODEVICE EX-SFP-10GE-ER40 run on multimode fiber?
A8: Not supported. This 1550nm high-power transceiver is exclusively designed for single-mode fiber. MMF deployment triggers heavy modal dispersion and prevents normal link activation.
 
Q9: Where can buyers purchase bulk HYTOPTODEVICE Juniper-compatible transceivers?
A9: Enterprise procurement teams can order bulk items through HYTOPTODEVICE website(Get a Quote) and Email. We provide tiered wholesale prices, customized enterprise solutions and efficient global shipment to support large-scale network construction.
