2.5G SFP Transceiver Module 20km

Description

Description:

The 2.5G SFP-BIDI Transceiver Module is a high-performance, cost-effective solution for long-distance fiber optic communication. Supporting dual data rates of 2.5Gbps and 2.125Gbps, this module delivers reliable performance over single-mode fiber (SMF) with a 20km transmission distance. The transceiver includes a 1550nm DFB laser transmitter and a PIN photodiode, integrated with a transimpedance amplifier (TIA) and a MCU control unit to ensure excellent signal integrity.

Designed for simplicity and compatibility, this SFP-BIDI transceiver supports SFP Multi-Source Agreement (MSA) and SFF-8472 standards, featuring a BIDI SC/UPC optical interface. This makes it an ideal choice for expanding network capabilities while keeping costs low. It is RoHS compliant, lead-free, and powered by a single +3.3V power supply.

Whether you’re building a high-speed backbone or expanding your fiber optic network, the 2.5G SFP-BIDI Transceiver offers outstanding durability with an operating temperature range from 0°C to +70°C (commercial), -10°C to +80°C (extended), and -40°C to +85°C (industrial), ensuring stability in harsh environments.

2.5G SFP Transceiver FEATURES:

• Dual Data Rates: Supports both 2.5 Gbps and 2.125 Gbps transmission speeds, allowing flexible network performance.
• Bidirectional Connection: Equipped with Bi-Directional LC connectors for efficient data transfer in both directions.
• Long-Distance Communication: Capable of 40 km transmission distance over Single-Mode Fiber (SMF), ideal for long-range fiber optic networks.
• Low Power Consumption: Consumes less than 0.8W of power, ensuring energy efficiency.
• Digital Diagnostic Monitor Interface: Provides real-time monitoring and diagnostics for improved network management.
• Industry Standards Compliance: Fully compliant with SFP MSA and SFF-8472 standards for seamless interoperability.
• Enhanced Durability: Features excellent ESD protection and low EMI for reliable performance in various environments.
• Temperature Range: Available in both commercial (0°C to 70°C) and industrial (-40°C to 85°C) operating temperature options.

2.5G SFP Transceiver Notes:

1. Circuit ground is internally isolated from chassis ground.
2. Laser output disabled on TDIS >2.0V or open, enabled on TDIS <0.8V.
3. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0V and 3.6V. MOD_DEF(0) pulls line low to indicate module is plugged in.
4. BDTRP413L1SN-20transceivers operate between OC-3 and OC-48, 1x and 2x Fiber Channel, and Gigabit Ethernet data rates and respective protocols without active control. BDTRP413L1SN-20 transceivers operate at 1x and 2x Fiber Channel, and Gigabit Ethernet data rates and respective protocols without active control.
5. LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation; logic 1 indicates loss of signal.
6. Absolute Maximum Ratings

Ⅲ. Electrical Characteristics (TOP = -40 to 85 ℃, VCC = 3.00 to 3.60 Volts)

2.5G SFP Transceiver Notes:

1. Non condensing.
2. AC coupled.
3. Or open circuit.
4. Into 100 ohm differential termination.
5. 20 – 80 %
6. LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
7. All transceiver specifications are compliant with a power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value applied through the power supply filtering network shown on page 23 of the Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA), September 14, 2000.
8. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ andDDJ.
9. Optical Characteristics (TOP = 0 to70℃, VCC = 3.00 to 3.60 Volts)
