Questions & Answers
What is the transmission distance of the SFP-GE-LH40-SM1310-BIDI module?
The module supports a maximum link length of 40 km over standard single-mode fiber (SMF).
Which optical wavelength does the SFP-GE-LH40-SM1310-BIDI operate on?
It transmits data at 1310 nm using bidirectional (BiDi) optics on a single fiber strand.
What data rate is supported by this SFP BiDi transceiver?
The SFP-GE-LH40-SM1310-BIDI supports 1 Gbps (Gigabit Ethernet) data rates.
What fiber type is compatible with the SFP-GE-LH40-SM1310-BIDI?
It is designed for use with standard single-mode fiber (SMF, ITU-T G.652).
Which connector interface does this module use?
It utilizes a duplex LC connector for both transmit and receive optical ports.
Is the SFP-GE-LH40-SM1310-BIDI hot-swappable?
Yes, it conforms to the SFP multi-source agreement (MSA) and supports hot-plug insertion and removal.
What temperature range can this SFP module operate in?
It operates reliably from –5 °C to +70 °C (23 °F to 158 °F) ambient temperature.
Does the module support Digital Diagnostics Monitoring (DDM)?
Yes, it offers real-time DDM for monitoring optical power, temperature, voltage, and TX/RX bias.
What compliance standards does the SFP-GE-LH40-SM1310-BIDI meet?
It meets IEEE 802.3z, SFP MSA, and RoHS compliance standards for environmental and performance requirements.
How does the bidirectional (BiDi) feature work on a single fiber?
BiDi optics use two different wavelengths (one for TX, one for RX) on a single SMF strand, enabling duplex transmission without separate fibers.
What is the typical transmit power range of this module?
Its typical output power ranges from –5 dBm to +2 dBm to ensure reliable reception over 40 km.
What receive sensitivity does the SFP-GE-LH40-SM1310-BIDI offer?
It features a receive sensitivity better than –23 dBm for stable signal integrity at maximum distance.
Can this module be used in CWDM or DWDM networks?
No, this SFP is optimized for single-channel 1310 nm SMF links and is not DWDM/CWDM multiplexed.
What applications are ideal for the SFP-GE-LH40-SM1310-BIDI?
It is ideal for campus backbones, Metro Ethernet, and long-haul Gigabit links requiring minimal fiber count.
What form factor and footprint does this transceiver use?
It conforms to the SFP (Small Form-Factor Pluggable) footprint for compact high-density installations.
How does this module ensure network reliability?
With DDM monitoring, industrial temperature tolerance, and robust optical power margins, it delivers high network uptime.
Is the SFP-GE-LH40-SM1310-BIDI backward-compatible with 100 Mbps links?
No, this module is specifically designed for 1 Gbps Ethernet and does not support 100 Mbps Fast Ethernet.
