Product details
Overview
AFBR-5813TQZ from Broadcom is a 125-Mbaud Fast Ethernet optical transceiver in a 1×9 package with ST duplex fiber connector, implementing IEEE 802.3u 100BASE-FX and FDDI physical layer interfaces using 1300-nm InGaP LED transmitter and InGaAs PIN photodiode receiver for multimode fiber links up to 2 km.
For engineers reviewing the AFBR-5813TQZ datasheet, pinout, applications, or equivalent options, this transceiver delivers LVPECL-compatible differential I/O, industrial temperature operation (–40°C to +85°C), single 3.3V supply, and RoHS-compliant wave-solderable packaging - critical for backbone and wiring-closet-to-desktop fiber media conversion.
Technical Context
The AFBR-5813TQZ integrates an AC-coupled, internally terminated LVPECL/LVDS differential input stage driving a 1300-nm InGaP LED, with optical output power ranging from –23.5 dBm (50/125-μm) to –17 dBm (62.5/125-μm), extinction ratio ≥10 dB, and spectral width ≤147 nm FWHM.
Its receiver uses an InGaAs PIN photodiode coupled to a transimpedance amplifier and quantizer, delivering LVPECL-compatible differential data output (RD+/RD–) and single-ended signal detect (SD), with sensitivity down to –31 dBm (BER < 1×10⁻¹⁰) and Rx_LOS hysteresis of 1.5 dB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 125 Mbaud - supports IEEE 802.3u 100BASE-FX and FDDI without autonegotiation pulses. |
| Optical Wavelength | 1270–1380 nm - centered at 1308 nm for optimal coupling into 50/125-μm and 62.5/125-μm multimode fiber. |
| Transmit Power | –23.5 to –13 dBm (50/125-μm); –20 to –13 dBm (62.5/125-μm) - ensures ≥2 km reach on standard MMF with margin. |
| Receiver Sensitivity | –31 dBm (avg., PRBS7, BER < 1×10⁻¹⁰) - enables robust link budget in noisy industrial environments. |
| Supply Voltage | 3.13–3.47 V - tight 3.3V tolerance allows direct connection to standard LDOs without external regulation. |
| Operating Temp | –40°C to +85°C - qualified for uncontrolled industrial enclosures and outdoor telecom cabinets. |
| Signal Detect Range | Asserts at ≥–33 dBm; deasserts at ≤–45 dBm - provides 1.5 dB hysteresis to prevent false LOS toggling. |
Pinout & Package
AFBR-5813TQZ uses a standard 1×9 SIP (Single In-line Package) with 9 signal pins and two mechanical solder posts (non-electrical). The package height complies with duplex ST connector clearance requirements and features a filled nonconductive plastic housing with threaded ST ports.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VEER | Receiver ground | Must connect directly to host PCB ground plane - no series impedance or filtering. |
| 2 RD+ | Receiver differential data output (+) | LVPECL-compatible; requires 50Ω termination to VCC–2V at receiving IC input. |
| 3 RD– | Receiver differential data output (–) | Paired with RD+; forms fully differential output path with <0.4 ns DCD. |
| 4 SD | Signal detect output | DCPECL logic "1" when valid optical input present; "0" otherwise - drives upstream SerDes LOS input. |
| 5 VCCR | Receiver power supply | +3.3V filtered locally; decoupling capacitor must be placed within 5 mm of pin. |
| 6 VCCT | Transmitter power supply | +3.3V filtered separately from VCCR; avoids noise coupling between Tx/Rx sections. |
| 7 TD– | Transmitter differential data input (–) | AC-coupled, internally terminated 100Ω differential input - accepts LVPECL/LVDS signals. |
| 8 TD+ | Transmitter differential data input (+) | Paired with TD–; no DC bias required - invalid DC input yields zero optical output. |
| 9 VEET | Transmitter ground | Separate ground return for Tx section; connects to same ground plane as VEER but via low-inductance path. |
Key Features
| Feature | Design Value |
|---|---|
| FDDI & 100BASE-FX compliance | Fully interoperable with IEEE 802.3u and ANSI X3.263 FDDI PHY layers - no protocol translation needed. |
| Integrated AC coupling & termination | Eliminates need for external AC coupling capacitors and 100Ω differential termination resistors on TD+/TD– inputs. |
| Industrial-grade thermal performance | Validated operation from –40°C to +85°C with no derating - supports deployment in factory automation and rail systems. |
| Wave-solder and aqueous-wash compatible | Withstands 260°C peak solder temperature for 10 s - enables high-yield automated assembly without rework. |
| Laser Class 1 safety | LED-based emission certified to EN 60825-1 Edition 3.0 - no user-accessible hazardous radiation under any condition. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar optical transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AFBR-5813QZ | Identical 1×9 form factor and electrical specs, but uses SC duplex connector instead of ST. | Requires SC-compatible patch panels and fiber cables; not mechanically interchangeable with ST infrastructure. | Select when existing cabling plant uses SC connectors or when higher mating cycle durability is required. |
| AFBR-5823TQZ | 2×9 package with SFF-8472 DMI interface (SDA/SCL pins), Tx_Disable control, and real-time monitoring of temperature, bias current, and optical power. | Supports digital diagnostics and remote fault isolation - adds complexity and cost not needed in basic link applications. | Choose only if host system implements SFF-8472 monitoring or requires software-controlled transmitter disable. |
Compared with AFBR-5813QZ, AFBR-5813TQZ offers identical performance in ST-connectorized environments; compared with AFBR-5823TQZ, it provides lower-cost, simpler integration where digital diagnostics are unnecessary - reducing BOM count and firmware overhead.

FAQ
What is the maximum supported fiber distance for AFBR-5813TQZ?
The AFBR-5813TQZ supports up to 2 km over standard 50/125-μm or 62.5/125-μm multimode fiber, based on its minimum transmit power (–23.5 dBm for 50/125-μm), receiver sensitivity (–31 dBm), and typical link budget margin. Actual reach depends on fiber quality, splice loss, and connector insertion loss - design margin should include ≥3 dB overhead.
Does AFBR-5813TQZ support digital diagnostics (DMI) like SFF-8472?
No, AFBR-5813TQZ does not support SFF-8472 digital diagnostics. It is a 1×9 device without SDA/SCL pins or EEPROM memory. Only the 2×9 variants (e.g., AFBR-5823TQZ) include the DMI interface. AFBR-5813TQZ provides only analog signal detect (SD) and LVPECL data I/O.
What is the recommended termination for the RD+ and RD– outputs of AFBR-5813TQZ?
The RD+ and RD– outputs of AFBR-5813TQZ are LVPECL-compatible and require split-load termination: each line should terminate to VCC–2V (typically achieved with 130Ω to VCC and 82Ω to ground). This matches the 50Ω differential impedance while maintaining proper common-mode voltage - per Figure 10 in the AFBR-58x3xxZ-DS102 datasheet.
Can AFBR-5813TQZ operate with a 2.5V supply instead of 3.3V?
No. AFBR-5813TQZ is specified only for 3.13–3.47 V operation. Supplying 2.5V violates the Absolute Maximum Ratings and will result in undefined behavior, including failure to drive the LED transmitter or produce valid LVPECL output levels. A dedicated 3.3V LDO with local decoupling is mandatory.
Is AFBR-5813TQZ compliant with RoHS and REACH regulations?
Yes, AFBR-5813TQZ is RoHS I and II compliant per Directive 2011/65/EU Annex II and (EU) 2015-863, and meets REACH SVHC requirements. Its housing material is UL-certified 94V-0 flame-retardant plastic, and all plating and solder finishes conform to lead-free assembly standards.
