Questions & Answers
What is the SFP-GE-LH40-SM1550-BIDI transceiver?
The SFP-GE-LH40-SM1550-BIDI is a hot-pluggable 1 Gbps SFP module that delivers bidirectional 1550 nm single-mode fiber transmission up to 40 km using LC connectors.
Which fiber type and connector does the SFP-GE-LH40-SM1550-BIDI support?
It supports single-mode fiber (SMF) with LC duplex connectors for bidirectional data transmission over a single fiber strand.
What is the maximum transmission distance of this module?
This module provides reliable data transmission over distances up to 40 km on standard single-mode fiber.
What operating wavelength does the SFP-GE-LH40-SM1550-BIDI use?
It uses a 1550 nm receiver wavelength for downstream signals and transmits upstream on a complementary wavelength for bidirectional operation.
How does bidirectional (BiDi) technology work in this SFP?
Bidirectional technology uses two different wavelengths on a single fiber—one for transmit and one for receive—halving fiber consumption and simplifying deployment.
What data rate and standards does this SFP module support?
It supports 1 Gbps (1000Base-BX) in full compliance with IEEE 802.3z and SFP MSA specifications.
Is the SFP-GE-LH40-SM1550-BIDI hot-swappable?
Yes, the module is fully hot-swappable, allowing installation or removal without powering down the host device.
Does this transceiver support Digital Diagnostics Monitoring (DDM)?
Yes, it features SFF-8472–compliant DDM for real-time monitoring of optical power, temperature, voltage, and transmit/receive bias.
What is the operating temperature range for this module?
It operates reliably from 0 °C to 70 °C (commercial range) and offers an extended range option to –40 °C to 85 °C if required.
What is the typical power consumption of the SFP-GE-LH40-SM1550-BIDI?
Typical power draw is below 1 W (maximum 1.0 W), ensuring low energy usage and minimal heat generation.
What is the MTBF (Mean Time Between Failures) of this SFP transceiver?
The module offers an MTBF of over 1,000,000 hours, providing high reliability for critical network links.
How do I install the SFP-GE-LH40-SM1550-BIDI in my switch or router?
Simply insert the module into an available SFP port until it clicks, connect the LC fiber cable, and verify link status via your device’s management interface.
What are common applications for the 1550 nm, 40 km BiDi SFP?
Typical uses include campus backbones, metro rings, ISP access links, and fiber-to-the-home (FTTH) networks requiring long reach with minimal fiber.
Is this SFP module compatible with leading networking vendors?
Yes, it’s guaranteed compatible with major OEMs (Cisco, Juniper, HP, Dell, Huawei) when operating in generic or third-party mode.
Does the SFP-GE-LH40-SM1550-BIDI require any special configuration?
No special configuration is needed; it auto-negotiates with the host device and is ready for plug-and-play operation.
What warranty and support are provided with this SFP transceiver?
The module includes a 1-year warranty and lifetime online technical support for fault diagnosis and replacement guidance.
How can I verify the module’s link performance after installation?
Use your switch or router’s diagnostic interface or DDM software to monitor real-time optical power levels and error statistics.
