EX-SFP-10GE-ZR-BCC | Juniper Compatible 10GB Single-Mode ZR - 80km (10GBASE-ZR)

Q: Will this work in place of the Juniper EX-SFP-10GE-ZR?
A: Yes. The EX-SFP-10GE-ZR-BCC is electrically and optically equivalent to the Juniper EX-SFP-10GE-ZR and operates as a plug-and-play replacement. It complies with the same IEEE 802.3ae 10GBASE-ZR standard, uses the SFP+ form factor per SFF-8431/8432, and delivers the same 10.3125 Gbps data rate at 1550nm over single-mode fibre. Host platforms recognise it via SFF-8472 DDM and it integrates without configuration changes.

Q: Which Juniper platforms support this transceiver?
A: This transceiver is designed for Juniper switches and routers with SFP+ ports that support 10GBASE-ZR optics, including EX-series Ethernet switches (EX2300, EX3200, EX3300, EX3400, EX4200), QFX-series data centre switches, and SRX-series security platforms. Compatibility is determined by the SFP+ port type and JUNOS software support for 10GBASE-ZR. Consult the Juniper Hardware Compatibility Tool for your specific platform and software version.

Q: What fibre type and quality is required to achieve 80km reach?
A: This transceiver requires OS2 single-mode fibre (G.652 standard) to support 80km transmission. Actual reach depends on cumulative link budget: fibre attenuation (typically 0.25 dB/km at 1550nm for OS2), splice and connector losses, and any inline components. The module's optical budget is designed for 80km over clean, low-loss OS2 fibre. For marginal links or longer distances, verify total link loss against the transceiver's transmit power and receiver sensitivity specifications.

Q: Can I monitor link health and optical power levels in real time?
A: Yes. This transceiver implements SFF-8472 DDM (Digital Diagnostics Monitoring), exposing transmit optical power, receive optical power, module temperature, laser bias current, and supply voltage via the I2C management interface. These parameters are accessible through Juniper CLI commands (e.g., 'show interfaces diagnostics optics') or SNMP polling. DDM allows proactive detection of link degradation, such as rising attenuation or transmitter aging, before hard failures occur.

Q: What is the power consumption and thermal profile of this module?
A: This 10GBASE-ZR transceiver typically consumes less than 1.5W during operation. The cooled EML laser and APD receiver require active thermal management, so power draw is higher than shorter-reach optics like SR or LR. The module is rated for 0 to 70°C ambient and dissipates heat through the SFP+ cage and host chassis airflow. Ensure adequate ventilation in densely populated SFP+ line cards or switches to maintain thermal performance and longevity.
