LINK-PP LS-BL332725-20E is a 25G SFP28 BiDi optical transceiver that streamlines long-reach data transmission by sending and receiving data over a single fiber strand up to 20km. This single-mode module combines a DFB laser and PIN receiver with a simplex LC/UPC interface to optimize infrastructure efficiency. Additionally, integrated DOM capabilities provide continuous diagnostic tracking to ensure stable network operations across varied temperature ranges.
This module integrates a premium 1330nm DFB laser and a highly sensitive 1270nm PIN receiver to optimize optical signal integrity. The combination of these internal components guarantees reliable, low-latency data conversion. It delivers consistent optical power output while maintaining excellent receiver sensitivity.
Providing a full 25Gbps data rate, this transceiver directly addresses the bandwidth demands of modern regional edge nodes. It allows network operators to easily scale upstream capacity without needing to upgrade existing switch hardware slots. This makes it an efficient choice for accelerating localized data distribution.
By transmitting at 1330nm and receiving at 1270nm, the module utilizes bidirectional technology to split downstream and upstream traffic smoothly. This specific wavelength pair prevents signal crosstalk and permits clean, simultaneous two-way transport. It is highly optimized for standard single-mode fiber infrastructure.
Designed for mid-haul spans, this module comfortably covers link distances up to 20km without requiring inline optical amplification. Its strong power budget ensures that signal attenuation remains well within safe operational margins over long runs. This makes it highly dependable for bridging remote enterprise locations.
Featuring a single-core simplex LC/UPC connector, this module cuts the required physical fiber cabling straight in half. By consolidating traffic onto one fiber strand, it helps operators save precious patch panel space and significantly reduces deployment expenses. The standardized UPC polish also ensures ultra-low insertion loss at the connection point.
Equipped with built-in Digital Optical Monitoring (DOM), the transceiver continuously tracks vital stats like temperature, supply voltage, and laser bias current. Network administrators can easily view these real-time metrics to spot potential faults before they cause actual system downtime. This integrated diagnostic tool greatly simplifies routine field maintenance.

Q: High-speed 25G modules tend to get very hot. What is the power consumption on this SFP28 module? By A***e on 2026-04-18
A: Power consumption is kept low (typically under1.5W per module) running on a standard +3.3V supply. This low thermal footprint prevents switch backplanes from overheating when populating high-density 48-port top-of-rack switches. By admin on 2026-04-19
Q: What type of fiber connector patch cord do I need to buy to connect to this module? By Z***s on 2025-10-02
A: You will need a simplex LC single-mode (9/125µm) patch cable. Make sure to use a simplex LC connector rather than a duplex LC cable. By admin on 2025-10-03
Q: Our cabinet in Arizona easily hits 50°C in summer. Can this module handle extreme thermal conditions? By H***l on 2025-07-07
A: Yes, this module is built with an extended operating temperature range of -20°C to +85°C. It handles heat buildup inside sealed outdoor cabinets far better than standard commercial-grade modules (0°C to 70°C). By admin on 2025-07-08
Q: This module uses 1330nm-TX and 1270nm-RX. Does that mean I can't connect two identical modules to each other? By C***t on 2025-06-04
A: Correct! BiDi optics work in complementary pairs. To establish a link, End A must use this module (1330nm TX / 1270nm RX), and End B must use its matching pair (1270nm TX / 1330nm RX). If you use 1330nm on both ends, they won't hear each other. By admin on 2025-06-05
Q: If our field technician hot-plugs this module into an active outdoor switch, will it damage the unit or drop adjacent ports? By B***e on 2025-05-29
A: Not at all. It is fully hot-pluggable. You can insert or remove the module without powering down the host switch or disturbing neighboring active optical links. By admin on 2025-05-30
