Bcp 420B-33ST laser transmitter & 320A optical receiver
BCP (Broadband Communication Products), now JDS Uniphase 420B-33ST 2.5 Gb/s Ultra High Speed Laser Transmitter and 320A-33ST High Gain 3 GHz O/E Optical Receiver for 1550 nm Wavelength
Comes with what you see in the pictures. If you don't see it, you probably wont get it.
Specifications are from a BCP/JDS Uniphase and may vary slightly due to upgrades, options, or revisions this unit may or may not have.
The units are Intel surplus. They power up but we do not have the ability to formally test them. Guaranteed non DOA.

The receiver detects and converts optical signals into electrical signals for the purpose of transmitter waveform analysis and testing, including error rate testing. It is optimized for analysis of high-speed, low-level optical signals from single-mode fiber sources. The high bandwidth (3 GHz) and high gain (2500 V/W) enable detection and analysis up to 2.5 Gb/s signals at levels down to below -30 dBm. The receiver is also equipped with a high-level input port for direct connection of laser sources at power levels up to +3 dBm without overload. The Model 320A 3 GHz O/E Receiver is the one solution that provides users with a low-cost, high-quality instrument for optical eye pattern analysis and testing at low to high power levels.
The receiver consists of a 3 GHz bandwidth optical-to-electrical (O/E) converter (1100 to 1600 nm) and a 3 Gb/s limiting amplifier. The detector out port for the O/E converter is DC coupled and automatically nulled to < +/- 100 µV DC. The nulling is automatically performed when the receiver does not have an optical input.
420B Transceiver Description:
The Model 420B Laser Transmitter is a very high speed, optically isolated and thermally stabilized fiber optic signal source designed for general laboratory use. The bench top instrument is fully connectorized for both RF inputs and optical output, and is AC line powered for any line source from 100 to 240 VAC. The unit accepts digital or analog input signals for direct modulation to beyond 2.5 Gb/s, with analog bandwidth over 2.5 GHz. The 420B generates a fiber-coupled optical output which can be used for testing detectors, receives, or any other component requiring temperature controlled, stable and flexible DFB laser optical source.
The 420A meets all applicable SONET/SDH standards from 51.84 Mb/s to 2.488 Gb/s (Reference Bellcore GR-253-CORE and ITU G.957 specifications), making it ideal for production receiver or system compliance proof-of-performance testing. The transmitter will also find application as either an analog or digital optical source in critical fiber optic link applications.
In the digital mode, both DC and AC-coupled digital inputs are front panel selectable. The DC-coupled digital input permits the user to operate completely independent of data pattern effects. The DC-coupled digital input will accept any ECL-level input pulse pattern, ranging from a DC level to isolated sub-nanosecond pulses, including continuous or burst mode formats. The AC-coupled digital input enables the user to interface with alternative non-ECL digital signal sources with widely varying DC logic levels.
The AC-coupled digital input also provides a mode with the lowest possible source-generated jitter. The AC logic threshold on the 420B digital input is front panel adjustable in the AC-coupled digital input mode to enable the user to optimize output pulse width and jitter for specific applications. The DFB laser bias point is rear panel adjustable within a limited range for extinction ratio and waveform control.
In the analog mode, the laser output is set between -3 and 0 dBm, and the AC-coupled analog input signal is routed directly to the laser through a termination and surge protection circuit. The optical modulation index is settable by input level from 0% to 80% minimum. This operating mode is highly useful for testing the linear bandwidth of detectors and detector-receiver combinations to beyond 2.5 GHz.
A universal optical connector interface on the front panel permits the optical connector to be user-changeable. Simple screw-on connector adapters for all industry-standard connector types are available. This connector also allows easy optical cleaning without removing the instrument cover. When the instrument is not in use, the permanently attached dust cap simply snaps in place over any type of adapter.
