Juniper compatible EX-SFP-10GE-SR Description
EX-SFP-10GE-SR is a Juniper part number (also listed as 740-021308) for a 10GBASE-SR SFP+ transceiver designed for EX series switches. Juniper assigns separate SKUs to different product lines, so the same optical module appears as QFX-SFP-10GE-SR on QFX switches and SRX-SFP-10GE-SR on SRX firewalls. All three part numbers reference the same 850 nm multimode SR optic with identical electrical and optical parameters. EdgeOptic's compatible replacement matches the original specifications and programs the EEPROM with Juniper-recognized vendor data, so no CLI overrides or unsupported-transceiver commands are needed on EX, QFX, or SRX platforms.
The module uses an 850 nm VCSEL transmitter and PIN photodiode receiver, conforming to IEEE 802.3ae 10GBASE-SR. Optical budget is 6.1 dB minimum, supporting 300 m over OM3 multimode fiber and 400 m over OM4. Reach figures assume standard cable attenuation and splice losses; actual distance depends on the installed fiber plant condition. The LC duplex interface accepts standard multimode patch cords with no polarity adapters required. Operating temperature range covers 0°C to 70°C, suitable for standard network equipment rooms and wiring closets.
DDM (Digital Diagnostics Monitoring) reports transmit power, receive power, bias current, temperature, and supply voltage in real time. These parameters are accessible through Junos OS CLI commands and SNMP, enabling proactive link health monitoring across the EX, QFX, and SRX platforms.
Data rate support covers 1.25 Gbps to 10.3125 Gbps, making the module compatible with 10GbE and 1GbE ports that accept SFP+ optics. The transceiver conforms to SFF-8431 and SFF-8432 mechanical and electrical specifications. CE and RoHS certified.
EdgeOptic tests each EX-SFP-10GE-SR compatible module against current Juniper EX, QFX, and SRX firmware releases before shipment. Every unit passes optical power verification and EEPROM validation. For bulk pricing or platform-specific questions, contact our sales team.
Frequently Asked Questions
Can the same compatible module be used in EX, QFX, and SRX platforms?
Yes. EX-SFP-10GE-SR, QFX-SFP-10GE-SR, and SRX-SFP-10GE-SR are different part numbers for the same 10GBASE-SR optic. EdgeOptic's compatible module carries Juniper-recognized EEPROM coding that all three product lines accept without configuration changes.
What is the relationship between EX-SFP-10GE-SR and Juniper part number 740-021308?
740-021308 is Juniper's internal internal ordering code that maps to EX-SFP-10GE-SR. Both identifiers appear in Juniper price lists and hardware compatibility matrices. They refer to the same transceiver.
