SFPP-10G-SR-ET-C Juniper Compatible 10GBASE-SR SFP+ Extended Temp

EdgeOptic's SFPP-10G-SR-ET-C compatible is a Juniper-coded 10GBASE-SR SFP+ transceiver in the extended-temperature commercial grade. The -ET-C suffix marks it apart from the standard 0 to 70 degrees Celsius commercial part and from industrial-only (-I) variants. Case operating range is -40 to +85 degrees Celsius; the optical stage and line rate remain identical to the standard SR part. Typical host platforms include the Juniper EX4300 and EX4600 campus switches, the QFX5100 and QFX5110 data-center top-of-rack switches, the MX80 and MX104 edge routers, and the ACX access and aggregation series. These platforms often sit in outdoor cabinets and industrial enclosures where ambient temperatures exceed the 70 degree commercial ceiling.

The optical stage follows IEEE 802.3ae Clause 52: 10.3125 Gbps line rate, 850 nm VCSEL transmitter, 850 nm PIN photodiode receiver, and a 6.1 dB link budget covering 300 m over OM3 multimode fiber and 400 m over OM4, both on a duplex LC interface. OM2 reach is approximately 82 m and OM1 approximately 33 m for legacy multimode plants. Mechanical envelope is the SFP+ MSA (SFF-8432) with SFF-8472 digital diagnostics exposing TX power, RX power, laser bias current, supply voltage and case temperature. On Junos the diagnostic page is readable through 'show interfaces diagnostics optics' on the SFP+ interface, The extended-temp rating applies when the case sensor reports temperatures beyond the standard commercial window in outdoor cabinet builds.

EdgeOptic programs the EEPROM with Juniper identifiers so Junos registers the module as a native SFPP-10G-SR-ET-C on EX, QFX, MX and ACX platforms. This part is a temperature-graded variant on the standard 10GBASE-SR optical platform, not a separate industrial-root product line; it keeps the SR reach and budget and adds headroom on the case operating range. The module conforms to the SFP+ MSA and is CE/RoHS certified.
