The EX-SFP-10GE-ERD4931-C is a DWDM SFP+ transceiver operating at 1549.32 nm, supporting 10 GbE data rates over single-mode fiber up to 40 km, fully compatible with Juniper EX series.
This EX-SFP-10GE-ERD4931-C module is fully interoperable with Juniper EX2200, EX2300, EX3300, EX4200, EX4300, EX4550 and EX9200 platforms.
It uses a standard LC duplex connector designed for single-mode fiber, ensuring low insertion loss and reliable optical coupling.
The module supports optical transmission distances up to 40 km (25 mi) over ITU-G.652 single-mode fiber at 10 Gbps.
Yes, this SFP+ DWDM transceiver is hot-swappable, allowing you to install or replace it without powering down your Juniper EX switch.
The EX-SFP-10GE-ERD4931-C is tuned to ITU channel 31 at a central wavelength of 1549.32 nm for dense wavelength-division multiplexing.
No. DWDM modules like the 1549.32 nm SFP+ require a DWDM MUX/DEMUX and ITU-grid fiber; they are not compatible with CWDM wavelength plans.
It supports line speeds of 9.95 to 11.3 Gbps, optimized for 10 Gigabit Ethernet applications.
Yes, it is designed for multi-vendor interoperability and has been validated with common DWDM systems from Cisco, Arista, Ciena and others.
The module consumes less than 1.2 W in active operation, complying with SFF-8431 and SFF-8472 MSA specifications.
Operating temperature: 0 °C to 70 °C (32 °F to 158 °F); relative humidity: 5% to 85% non-condensing.
No calibration is needed. The module is factory-tuned to 1549.32 nm and auto-negotiates with Juniper EX hardware upon insertion.
Use the Juniper CLI show interface transceiver diagnostics command to view real-time temperature, voltage, TX/RX power and optical wavelength.
We offer a lifetime warranty against defects plus free lifetime technical support and advance replacement for Juniper EX compatible modules.
Place an online order via our website SKU EX-SFP-10GE-ERD4931-C or contact sales@yourcompany.com for bulk pricing and availability.
