Product Description

Product Description

SUN-SFP28-25G-LR Optical Transceiver

Sun Telecom's SUN-SFP28-25G-LR SFP transceiver is designed to transmit and receive optical data over single mode optical fiber for link length 10km. The SFP28 LR module electrical interface is compliant to SFI electrical specifications.
The transmitter input and receiver output impedance is 100 Ohms differential. Data lines are internally AC coupled. The module provides differential termination and reduce differential to common mode conversion for quality signal termination and low EMI. SFI typically operates over 200 mm of improved FR4 material or up to about 150mmof standard FR4 with one connector.
The transmitter converts 25Gbit/s serial PECL or CML electrical data into serial optical data compliant with the 25GBASE-LR standard.

Features

1. 25Gb/s serial optical interface
2. 1310nm DFB transmitter, PIN photo-detector
3. 2-wire interface for management specifications compliant with SFF 8472
   digital diagnostic monitoring interface for optical transceivers
4. Advanced firmware allow customer system encryption information to be stored in transceiver
5. Cost effective SFP28 solution, enables higher port densities and greater bandwidth
6. Operating case temperature

Standard: 0~+70°C
Industrial: -40~+85°C

Applications

1. High-speed storage area networks
2. Computer cluster cross-connect
3. Custom high-speed data pipes
