EX-SFP-GE10KT14R13-BCC | Juniper Compatible 1GB BiDi Transceiver - 10km (1000BASE-BX-D)

Q: Will this work in place of the Juniper EX-SFP-GE10KT14R13?
A: Yes. This transceiver is a direct replacement based on 1000BASE-BX10-D standard compliance, matching the SFP form factor, 1.25 Gbps data rate, and 1490nm TX / 1310nm RX wavelength specification. It is plug-and-play in any Juniper equipment that lists the EX-SFP-GE10KT14R13 as a supported transceiver.

Q: Which Juniper platforms support this transceiver?
A: This module is compatible with Juniper switches, routers, and security appliances that feature Gigabit Ethernet SFP ports and support 1000BASE-BX10 operation. This includes platforms across the EX, MX, SRX, QFX, and ACX families. Confirm compatibility by verifying your platform supports the EX-SFP-GE10KT14R13 in Juniper's Hardware Compatibility Tool.

Q: Why must this transceiver be paired with a specific complementary module?
A: BiDi transceivers use wavelength division multiplexing (WDM) to achieve bidirectional communication over a single fibre. This module transmits at 1490nm and receives at 1310nm (the -D or downlink side). The opposite end must use a transceiver that transmits at 1310nm and receives at 1490nm (the -U or uplink side, such as EX-SFP-GE10KT13R14). Mismatched wavelengths prevent link establishment.

Q: What is the actual reach over installed single-mode fibre?
A: The 10km specification assumes standard OS1 or OS2 single-mode fibre with typical attenuation of 0.35 to 0.5 dB/km at 1310nm and 1490nm, plus connector and splice losses. The module provides sufficient link budget (typically 15 to 18 dB) to support 10km under normal conditions. Actual reach depends on total path loss, which should be verified with an optical power meter or calculated from fibre plant records.

Q: Can this transceiver operate in CWDM or DWDM systems?
A: No. This is a fixed-wavelength BiDi transceiver designed for point-to-point links between matched pairs. It is not a tunable or CWDM/DWDM-compatible module. The 1490nm and 1310nm wavelengths fall outside standard CWDM ITU grid channels. For wavelength multiplexing applications, use dedicated CWDM or DWDM transceivers with the appropriate channel spacing and multiplexer equipment.
