The Huawei 10G 1270TX/1330RX 10km SM eSFP BBU Module, part number 34060544 001, is a high performance optical transceiver module designed for 10 Gigabit Ethernet applications. It is specifically engineered to support long distance transmission over single mode fiber, with a reach of up to 10 kilometers. Here are the key specifications and characteristics of this module:

Basic Information:

1. Type: 10 Gigabit Ethernet SFP+ (Small Form factor Pluggable Plus) transceiver.

2. Wavelength: The transmitter operates at two wavelengths, 1270 nm and 1330 nm, which are common for long haul communications.

3. Interface: SFP+ interface, which is backward compatible with SFP interfaces.

4. Compliance: The module adheres to industry standards such as SFF 8431, SFF 8432, and IEEE 802.3ae.

5. Power Supply: It operates with a power supply of 3.3V.

6. Dimensions: The module is compact, measuring 50.75 mm x 13.00 mm x 71.00 mm (L x W x H).

7. Operating Temperature: It functions effectively in a wide temperature range from  5°C to +85°C.

Transmitter Receiver Characteristics:

1. Transmitter:

  Type: 10Gbps DFB (Distributed Feedback) Laser.

  Wavelength: 1270 nm and 1330 nm.

  Output Power: The module provides a high output power to ensure signal integrity over long distances.

  Modulation: The transmitter uses a modulation format suitable for 10Gbps data rates.

2. Receiver:

  Type: High sensitivity PIN (Positive Intrinsic Negative) photodiode.

  Sensitivity: The receiver is designed for high sensitivity to ensure reliable detection of the incoming signal.

  Wavelength: It is optimized for the same wavelengths as the transmitter (1270 nm and 1330 nm).

3. Optical Budget:

  The module offers a generous optical budget, which is the difference between the received power and the sensitivity of the receiver, allowing for additional loss in the system without compromising performance.

4. Connector:

  Type: LC (Lucent Connector) for easy and secure connection to the fiber.

5. Coding:

  Forward Error Correction (FEC): The module may support FEC to improve the signal to noise ratio and reduce bit error rates.

6. Data Rates:

  The module supports data rates up to 10.3125 Gbps, which is the standard rate for 10 Gigabit Ethernet.

7. Distance:

  Reach: The module is designed to support distances up to 10 kilometers over single mode fiber.

8. Environmental:

  Storage Temperature:  40°C to +70°C.

  Humidity: 5% to 95% non condensing.

9. Safety:

  The module meets safety standards such as CE, FCC, and RoHS.

This module is typically used in telecommunications, data centers, and other high speed networking environments where long distance, high capacity data transmission is required. Its robust design ensures reliable operation in various environmental conditions.
